Still, scientists have yet to see an extrasolar planet directly or even take a picture of one. Thus far, their presence has only been inferred from either their effect on the orbit of their host stars or by measuring the amount of infrared light they emit. The Spitzer Space Telescope is the only instrument that has successfully used the latter strategy. (To learn more about the Spitzer Space telescope, read Seeing the Invisible.). The job of finding and imaging extrasolar planets is extraordinarily difficult. The biggest challenge is the planets feeble luminosity. A star, fueled by nuclear reactions, is typically a billion times brighter than any orbiting planet, whose light is primarily reflected from the host star. This overwhelming brightness renders nearby extrasolar planets invisible to astronomers. Invisible does not mean undetectable, however.. The Telltale Wobble. One technique scientists use to detect extrasolar planets is to look for a slight wobble in the motion of the host stars. ...
Then he found the ratio of terrestrial planets to all the planets seen. Again, remember, this ratio was found for planets somewhat close in to their stars.. Then he plotted all the planets versus distance from their parent stars. For example, you see very few planets very close to the star (probably because its hard to form or get a planet to orbit that close in), then more as you get farther out, then fewer at some large distance (which may, once again, simply be due to the fact that planets with long orbital periods cant be seen in the short duration of the data). He then found an equation (called a mathematical fit) that did a good job predicting the shape of the plot. Once he had that, its easy enough to extrapolate it out to the distance of the habitable zones of the stars.. That gave him an estimate of all planets orbiting there, including gas and ice giants. Multiply by the ratio of terrestrial planets, and boom! 34% of stars like the Sun should have planets that are Earth-sized ...
Together with Paul Butler, Marcy quickly confirmed the reality of the 51 Pegasi planet using the method of precise Doppler measurement that he had developed for the purpose of extrasolar planet detection over many years. Seventy of the next 100 extrasolar planets discovered were found by his team. Many of these planets had distinctly non-circular orbits, in contrast with the orbits of known planets in our own Solar System. Several reside in systems where there is more than one giant planet, with multiple planets in a given system often having orbital periods that bear integer relationships to one another. As the observational sensitivity and the understanding of systematic errors steadily improve, planets with masses more like Saturn and Neptune are being found, instead of only the Jupiter-like bodies that characterized the initial discoveries. Significantly, there are no bodies that have masses appreciably in excess of 10 Jupiter masses. In a few cases, the orbital plane lies sufficiently ...
Most of the exoplanets we know of were found by the Kepler mission. While Kepler did find a few exoplanets with orbital periods longer than 100 days, they are more difficult to confirm. Also, since the transit method only tells us the size of a planet relative to its star, the Kepler data doesnt let us determine a planets mass. This is particularly troublesome for Jupiter-sized planets. Because the weight of a large planet causes it to compress more, a Jupiter-mass planet and a brown dwarf 30 times more massive can have roughly the same size. Determining the mass of these exoplanets is the goal of the Giant Outer Transiting Exoplanet Mass Survey, or the GOTEM Survey for short.. In this latest work, the team used a different way to study exoplanets known as the radial-velocity method. As a planet orbits its star, it tugs on the star gravitationally, causing the star to wobble slightly. When a star wobbles toward and away from us, the light of the star is shifted a bit to the blue and red in a ...
The more eccentric giant planet orbits result in drier terrestrial planets, Raymond said. Conversely, more circular giant planet orbits mean wetter terrestrial planets. In the case of our solar system, Jupiter s orbit is slightly elliptical, which could explain why Earth is 80 percent covered by oceans rather than being bone dry or completely covered in water miles deep. The findings are significant because of the discovery in recent years of a large number of giant planets such as Jupiter and Saturn orbiting other suns. The presence, and orbits, of those planets can be inferred from their gravitational interaction with their parent stars and their affect on light from those stars as seen from Earth. It currently is impossible to detect Earthlike planets around other stars. However, if results from the models are correct, there could be planets such as ours around a number of other suns relatively close to our solar system. A significant number of those planets are likely to be in the ...

Chemical kinetics plays an important role in controlling the atmospheric composition of all planetary atmospheres, including those of extrasolar planets. For the hottest exoplanets, the composition can closely follow thermochemical-equilibrium predictions, at least in the visible and infrared photosphere at dayside (eclipse) conditions. However, for atmospheric temperatures < ~2000 K, and in the uppermost atmosphere at any temperature, chemical kinetics matters. The two key mechanisms by which kinetic processes drive an exoplanet atmosphere out of equilibrium are photochemistry and transport-induced quenching. We review these disequilibrium processes in detail, discuss observational consequences, and examine some of the current evidence for kinetic processes on extrasolar planets.. Julianne I.

Abstract. It is well accepted that ;hot Jupiters and other short-period planets did not form in situ, as the temperature in the protoplanetary disc at the radius at which they now orbit would have been too high for planet formation to have occurred. These planets, instead, form at larger radii and then move into the region in which they now orbit. The exact process that leads to the formation of these close-in planets is, however, unclear and it seems that there may be more than one mechanism that can produce these short-period systems. Dynamical interactions in multiple-planet systems can scatter planets into highly eccentric orbits which, if the pericentre is sufficiently close to the parent star, can be tidally circularized by tidal interactions between the planet and star. Furthermore, systems with distant planetary or stellar companions can undergo Kozai cycles which can result in a planet orbiting very close to its parent star. However, the most developed model for the origin of short ...
Abstract: We embark on a detailed study of the lightcurves of Keplers most Earth-like exoplanet host stars using the full length of Kepler data. We derive rotation periods, photometric activity indices, flaring energies, mass loss rates, gyrochronological ages, X-ray luminosities and consider implications for the planetary magnetospheres and habitability. Furthermore, we present the detection of superflares in the lightcurve of Kepler-438, the exoplanet with the highest Earth Similarity Index to date. Kepler-438b orbits at a distance of 0.166AU to its host star, and hence may be susceptible to atmospheric stripping. Our sample is taken from the Habitable Exoplanet Catalogue, and consists of the stars Kepler-22, Kepler-61, Kepler-62, Kepler-174, Kepler-186, Kepler-283, Kepler-296, Kepler-298, Kepler-438, Kepler-440, Kepler-442, Kepler-443 and KOI-4427, between them hosting 15 of the most habitable transiting planets known to date from Kepler ...
No, Pluto did NOT have it coming, and no, this is not about feelings.. Ceres is a planet, and our solar system does not have only 8 planets, at least according to the equally legitimate geophysical planet definition. 19th century astronomers did not know that Ceres is in hydrostatic equilibrium and therefore a complex world that doesnt belong in the category of asteroids and comets. It makes little sense to lump objects that structurally and compositionally are much more akin to the larger planets than to asteroids and comets with the latter category. It also makes little sense to require an object to clear its orbit to be a planet. We cannot look only at where an item is; we have to look at the individual item and what it is. These small spherical worlds are planets that have most of the same features the rocky planets have; the only difference is they are smaller.. The notion that we have to limit the number of planets in the solar system because we cannot have too many makes absolutely ...
TY - JOUR. T1 - Thermochemical and photochemical kinetics in cooler hydrogen-dominated extrasolar planets. T2 - A methane-poor GJ436b?. AU - Line, Michael R.. AU - Vasisht, Gautam. AU - Chen, Pin. AU - Angerhausen, D.. AU - Yung, Yuk L.. PY - 2011/9/1. Y1 - 2011/9/1. N2 - We introduce a thermochemical kinetics and photochemical model. We use high-temperature bidirectional reaction rates for important H, C, O, and N reactions (most importantly for CH4 to CO interconversion), allowing us to attain thermochemical equilibrium, deep in an atmosphere, purely kinetically. This allows the chemical modeling of an entire atmosphere, from deep-atmosphere thermochemical equilibrium to the photochemically dominated regime. We use our model to explore the atmospheric chemistry of cooler (T eff , 103K) extrasolar giant planets. In particular, we choose to model the nearby hot-Neptune GJ436b, the only planet in this temperature regime for which spectroscopic measurements and estimates of chemical abundances now ...
Kepler 22-b: Earth-like planet confirmed Astronomers have confirmed the existence of an Earth-like planet in the habitable zone around a star not unlike our own. The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and has a temperature of about 22C. It is the closest confirmed…

N2 - Tidal dissipation in the satellites of a giant planet may provide sufficient heating to maintain an environment favorable to life on the satellite surface or just below a thin ice layer. In our own solar system, Europa, one of the Galilean satellites of Jupiter, could have a liquid ocean which may occasionally receive sunlight through cracks in the overlying ice shell. In such a case, sufficient solar energy could reach liquid water that organisms similar to those found under Antarctic ice could grow. In other solar systems, larger satellites with more significant heat flow could represent environments that are stable over an order of Aeons and in which life could perhaps evolve. We define a zone around a giant planet in which such satellites could exist as a tidally-heated habitable zone. This zone can ...
NASAs Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planets unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.. The oddball exoplanet, called WASP-12b, is one of a class of so-called hot Jupiters, gigantic, gaseous planets that orbit very close to their host star and are heated to extreme temperatures. The planets atmosphere is so hot that most molecules are unable to survive on the blistering day side of the planet, where the temperature is 4,600 degrees Fahrenheit. Therefore, clouds probably cannot form to reflect light back into space. Instead, incoming light penetrates deep into the planets atmosphere where it is absorbed by hydrogen atoms and converted to heat energy.. We did not expect to find such a dark exoplanet, said Taylor Bell of McGill University and the Institute ...
Abstract: The Doppler wobble induced by the extra-solar planet HD 134987b was first detected by data from the Keck Telescope nearly a decade ago, and was subsequently confirmed by data from the Anglo-Australian Telescope. However, as more data have been acquired for this star over the years since, the quality of a single Keplerian fit to that data has been getting steadily worse. The best fit single Keplerian to the 138 Keck and AAT observations now in hand has an root-mean-square (RMS) scatter of 6.6 m/s. This is significantly in excess of both the instrumental precision achieved by both the Keck and Anglo-Australian Planet Searches for stars of this magnitude, and of the jitter expected for a star with the properties of HD134987. However, a double Keplerian (i.e. dual planet) fit delivers a significantly reduced RMS of 3.3 m/s. The best-fit double planet solution has minimum planet masses of 1.59 and 0.82Mjup, orbital periods of 258 and 5000d, and eccentricities of 0.23 and 0.12 respectively. ...
By analyzing planets orbiting a star called Kepler-32, astronomers at Caltech estimate that there are at least 100 billion planets in our galaxy.. Pasadena, California -Look up at the night sky and youll see stars, sure. But youre also seeing planets-billions and billions of them. At least.. Thats the conclusion of a new study by astronomers at the California Institute of Technology (Caltech) that provides yet more evidence that planetary systems are the cosmic norm. The team made their estimate while analyzing planets orbiting a star called Kepler-32-planets that are representative, they say, of the vast majority in the galaxy and thus serve as a perfect case study for understanding how most planets form.. Theres at least 100 billion planets in the galaxy-just our galaxy, says John Johnson, assistant professor of planetary astronomy at Caltech and coauthor of the study, which was recently accepted for publication in the Astrophysical Journal. Thats mind-boggling.. Its a staggering ...
The team used the K2 data to further characterize the orbits of the other six planets, help rule out the presence of additional transiting planets, and determine the rotation period and activity level of the star. They also discovered that TRAPPIST-1s seven planets appear linked in a complex dance known as an orbital resonance where their respective orbital periods are mathematically related and slightly influence each other. Resonances can be tricky to understand, especially between three bodies. But there are simpler cases that are easier to explain, Luger said. For instance, closer to home, Jupiters moons Io, Eu-ropa and Ganymede are set in a 1:2:4 resonance, meaning that Europas orbital period is exactly twice that of Io, and Ganymedes is exactly twice that of Europa.. These relationships, Luger said, suggested that by studying the orbital velocities of its neighbor planets they could predict the exact orbital velocity, and hence also orbital period, of TRAP-PIST-1h even before the K2 ...
The main advantage of the transit method is that the size of the planet can be determined from the lightcurve. When combined with the radial-velocity method (which determines the planets mass) one can determine the density of the planet, and hence learn something about the planets physical structure. The planets that have been studied by both methods are by far the best-characterized of all known exoplanets.[11]. The transit method also makes it possible to study the atmosphere of the transiting planet. When the planet transits the star, light from the star passes through the upper atmosphere of the planet. By studying the high-resolution stellar spectrum carefully, one can detect elements present in the planets atmosphere. A planetary atmosphere (and planet for that matter) could also be detected by measuring the polarisation of the starlight as it passed through or is reflected off the planets atmosphere.. Additionally, the secondary eclipse (when the planet is blocked by its star) allows ...
We present the detection of five planets-Kepler-62b, c, d, e, and f-of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii (R[subscript ⊕]), orbiting a K2V star at periods of 5.7, 12.4, 18.2, 122.4, and 267.3 days, respectively. The outermost planets, Kepler-62e and -62f, are super-Earth-size (1.25 R[subscript ⊕] , planet radius ≤ 2.0 R[subscript ⊕]) planets in the habitable zone of their host star, respectively receiving 1.2 ± 0.2 times and 0.41 ± 0.05 times the solar flux at Earths orbit. Theoretical models of Kepler-62e and -62f for a stellar age of ~7 billion years suggest that both planets could be solid, either with a rocky composition or composed of mostly solid water in their bulk ...
Planets in astrology have a meaning different from the modern astronomical understanding of what a planet is. Before the age of telescopes, the night sky was thought to consist of two very similar components: fixed stars, which remained motionless in relation to each other, and wandering stars (Ancient Greek: ἀστέρες πλανῆται asteres planetai), which moved relative to the fixed stars over the course of the year. To the Greeks and the other earliest astronomers, this group consisted of the five planets visible to the naked eye and excluded Earth. Although strictly, the term planet applied only to those five objects, the term was latterly broadened, particularly in the Middle Ages, to include the Sun and the Moon (sometimes referred to as Lights[1]), making a total of seven planets. Astrologers retain this definition today. To ancient astrologers, the planets represented the will of the gods and their direct influence upon human affairs. To modern astrologers, the planets ...
In the search for planets similar to our own, an important point of comparison is the planets density. A low density tells scientists that a planet is more likely to be gaseous like Jupiter, and a high density is associated with rocky planets like Earth. But a new study suggests some are less dense than previously thought because of a second, hidden star in their systems.. As telescopes stare at particular patches of sky, they cant always differentiate between one star and two. A system of two closely orbiting stars may appear in images as a single point of light, even from sophisticated observatories such as NASAs Kepler space telescope. This can have significant consequences for determining the sizes of planets that orbit just one of these stars, says a forthcoming study in the Astronomical Journal by Elise Furlan of Caltech/IPAC-NExScI in Pasadena, California, and Steve Howell at NASAs Ames Research Center in Californias Silicon Valley.. Our understanding of how many planets are small ...
At the center of the Solar System is the Sun. It is a star, like the billions of other stars in the sky. The other stars are very, very far away, so they look tiny. The Sun is important to us because it gives us heat and energy that allows life. None of the life on Earth could exist without the Sun.[3]. The rest of the things in the Solar System orbit (travel around) the Sun. The planets are the largest of these. Each planet is a little like the Earth. But the planets are also very different from each other.. Many of the planets have moons. A moon orbits a planet. Mercury has no moons[4] and nor does Venus. Earth has one. Jupiter has 63![5]. The planets closest to the Sun are called the inner planets. These are Mercury, Venus, Earth, and Mars. Then comes a big ring of asteroids, chunks of rock much smaller than planets. This ring is called the asteroid belt. Within the asteroid belt, there is a dwarf planet (smaller than a normal planet) named Ceres. Then come the outer planets: Jupiter, Saturn, ...
This puts Gliese 832c in the habitable or Goldilocks zone in its solar system - a sweet spot where it is neither too hot nor too cold for liquid water to exist upon the planets surface.. With an outer giant planet and an interior potentially rocky planet, this planetary system can be thought of as a miniature version of our Solar System, said professor Chris Tinney of the University of New South Wales where the super-Earth was discovered.. If the planet has a similar atmosphere to Earth it may be possible for life to survive, although seasonal shifts would be extreme, he added.. ...

In the past 15 years, astronomers have revealed that a significant fraction of the stars should harbour planets and that it is likely that terrestrial planets are abundant in our galaxy. Among these planets, how many are habitable, i.e. suitable for life and its evolution? These questions have been discussed for years and we are slowly making progress. Liquid water remains the key criterion for habitability. It can exist in the interior of a variety of planetary bodies, but it is usually assumed that liquid water at the surface interacting with rocks and light is necessary for emergence of a life able to modify its environment and evolve. The first key issue is thus to understand the climatic conditions allowing surface liquid water assuming a suitable atmosphere. These have been studied with global mean one-dimensional (1D) models which have defined the `classical habitable zone, the range of orbital distances within which worlds can maintain liquid water on their surfaces (Kasting et al. 1993).

The analysis was undertaken as if we were aliens looking at Earth with the tools we might have in 10 years and did not already know Earths composition, Cowan said. You sum up the brightness into a single pixel in the telescopes camera, so it truly is a pale blue dot.. Since Earths colors changed throughout the 24-hour-long observations, the scientists made maps of the planet in the dominant red and blue colors and then compared their interpretations with the actual location of the planets continents and oceans.. You could tell that there were liquid oceans on the planet, Cowan said. The idea is that to have liquid water the planet would have to be in its systems habitable zone, but being in the habitable zone doesnt guarantee having liquid water.. The observations on March 18 and June 4, 2008 were made when the spacecraft was between 17 million and 33 million miles from Earth, and while it was directly above the equator. Observations from above a polar region likely would show up ...
Potentially habitable planets can orbit close enough to their host star that the differential gravity across their diameters can produce an elongated shape. Frictional forces inside the planet prevent the bulges from aligning perfectly with the host star and result in torques that alter the planets rotational angular momentum. Eventually the tidal torques fix the rotation rate at a specific frequency, a process called tidal locking. Tidally locked planets on circular orbits will rotate synchronously, but those on eccentric orbits will either librate or rotate super-synchronously. Although these features of tidal theory are well known, a systematic survey of the rotational evolution of potentially habitable exoplanets using classic equilibrium tide theories has not been undertaken. I calculate how habitable planets evolve under two commonly used models and find, for example, that one model predicts that the Earths rotation rate would have synchronized after 4.5 Gyr if its initial rotation period was 3

Hot Jupiters are thought to form far from their stars (about where our Jupiter is within the solar system) and then migrate inward due to forces from other planets. The Northwestern researchers modeled a system in which a Jovian-sized planet is joined with another planet even farther out. Over long periods of time, the Jovian planet is nudged closer to its star. In some cases, the tidal effects of the second planet can cause the Jupiter-like planet to first achieve a highly elongated eccentric orbit, and then to flip and start rotating in the opposite direction ...
Standish agreed that the tidal effects of the planets upon the Earth will be negligible. If all the planets were in a straight line, it would raise the tide only 1/600 hundreds of an inch, so the planets have virtually no effect, he said. A baseball held at arms length would have a tidal effect millions of times stronger on a person than the planet Mars at its closest, Yeomans and Edberg said.. The planetary alignment wont provide much of a visual spectacle, either. The Earth and moon will be on the opposite side of the sun from the other aligned planets. The suns glare will hide the other planets, making the event as much of a no-show for skywatchers as it is for doomwatchers.. It will be like trying to look at a search light with little fireflies around it, Standish said.. Only the moon, Mars and Venus may be far enough from the sun and bright enough to be seen, with Venus appearing in the eastern dawn sky and the moon and Mars in the western sky just after sunset.. ...
Gaia could also play a role in the search for habitable worlds, not by directly detecting terrestrial planets, but by finding systems with a giant planet orbiting far from a solar-type star, a condition that would increase the possibility of finding an inner terrestrial planet harbouring life.. Increasingly more powerful computers will allow numerical simulations of planetary formation and evolution to develop rapidly, providing an invaluable tool for theoretical studies in this field.. Planetary Detection Methods. There are a number of different methods through which planets are being searched for:. ...
NASAs Kepler mission has verified 1,284 new planets - the single largest finding of planets to date. And its possible for life to exist on nine of them. In the newly-validated batch of planets, nearly 550 could be rocky planets like Earth, based on their size. Nine of them orbit in their suns habitable zone, which is the distance from a star where orbiting planets can have surface temperatures that allow liquid water to pool, NASA said. With the addition of these nine, 21 exoplanets now are known to be members of this exclusive group. Posted By PSmooth

Warm Neptunes are thought to have either rocky or liquid cores, surrounded by gas. If helium is indeed the dominant component in their atmospheres, the planets would appear white or gray. By contrast, the Neptune of our own solar system is a brilliant azure blue. The methane in its atmosphere absorbs the color red, giving Neptune its blue hue.. A lack of methane in one particular warm Neptune, called GJ 436b, is in fact what led Hu and his team to develop their helium planet theory. Spitzer had previously observed GJ 436b, located 33 light-years away, and found evidence for carbon but not methane. This was puzzling to scientists, because methane molecules are made of one carbon and four hydrogen atoms, and planets like this are expected to have a lot of hydrogen. Why wasnt the hydrogen linking up with carbon to produce methane?. According to the new study, the hydrogen might have been slow-cooked off the planet by radiation from the host stars. With less hydrogen around, the carbon would pair ...
Even in ancient times, people observed the planets that orbit our Sun. Nowadays we know that there are many trillions of other stars in the Universe. It seems likely that planets orbit many of these stars too. The evidence that extrasolar planets exist was obtained for the first time in the 1990s. However, these planets are small, non-luminous bodies that are light years away - how are we able to prove that they exist?
Tidally-locked planets - planets with one side perpetually facing their star while the other remains shrouded in darkness - tend to be warmer on one side than the other. The presence of an atmosphere can help distribute the heat across the planet, equalizing the temperatures. But tidal locking could result in wide climate variations, a result that could threaten the evolution of life on the surface of these planets.
The recent detection of Earth-sized planets in the habitable zone of Proxima Centauri, Trappist-1 and many other nearby M-type stars has led to speculations, whether liquid water and life actually exist on these planets. To a large extent, the answer depends on their yet unknown atmospheres, which may though be within observational reach in the near future by JWST, ELT and other planned telescopes. We consider the habitability of planets of M-type stars in the context of their atmospheric properties, heat transport and irradiation. Instead of the traditional definition of the habitable zone, we define the bio-habitable zone, where liquid water and complex organic molecules can survive on at least part of the planetary surface. The atmospheric impact on the temperature is quantified in terms of the heating factor (a combination of greenhouse heating, stellar irradiation, albedo etc.) and heat redistribution (horizontal energy transport).. We investigate the bio-habitable domain (where planets can ...
2009 is the year dedicated to astronomy. Five planets were already found in 55 Cancri the system that looks like our solar system. According to Nasa: This artists concept illustrates two planetary systems - 55 Cancri and our own. Blue lines show the orbits of planets, including the dwarf planet Pluto in our solar system. The 55 Cancri system is currently the closest known analogue to our solar system, yet there are some fundamental differences. The similarities begin with the stars themselves, which are about the same mass and age. Both stars also host big families of planets. Our solar system has eight planets, while 55 Cancri has five, making it the record-holder for having the most known exoplanets. In fact, 55 Cancri could have additional planets, possibly even rocky ones that are too small to be seen with current technologies. All of the planets in the two systems have nearly circular orbits. In addition, both planetary systems have giant planets in their outer regions. The giant ...
Dalpeangee eui byeol (Planet of Snail). A love story like no other, Planet of Snail is a mesmerizing documentary by Korean director Seung-Jun Yi, about an accomplished young poet who can no longer hear or see and his relationship to the world around him.. Young-Chan comes from the Planet of Snail. Dwellers of this tiny planet are deaf and blind, and call themselves snails because they rely only on their tactile senses, and communicating by touch. Young-Chan was not happy with the lethargic life on the planet. When Young-Chan came to Earth, there was nothing Earth offered him. Worse was that nobody understood his language. When he was desperate, an angel walked into his life.. Young-Chan meets Soon-Ho who becomes his wife and soul mate, an inseparable part of his life, and a window to the outside world. Young-Chan and Soon-Ho communicate through finger braille, a unique form of touch-based sign language in which words are tapped out on each others hands. They rely on one another completely. ...
Habitability. Finding nitrogen has an interesting implication for Earth-sized exoplanets. The definition of habitability is the presence of stable liquid water. We usually define a stars habitable zone, for example, as the region around the star where liquid water could exist on a rocky planets surface given a thick enough atmosphere. This is usually based on the amount of sunlight the planet receives from the star.. To get a clearer sense of habitability, Schwieterman pointed out, nitrogen could serve as an indicator for an atmosphere thick enough to maintain stable surface water. If you dont have a thick enough atmosphere, then the water isnt stable on the surface. It evaporates into the atmosphere. If we can confirm other planets have a similar amount of nitrogen as the Earth, we can rule that possibility out. If other habitable terrestrial exoplanets are like the Earth, their atmospheres would be nitrogen-dominated.. An example of this is in our own solar system - on Mars. Billions ...
Artists concept of an exoplanet and its moon transiting a sun-like star. Such a system could be used to directly weigh the star. Credit: David A. Aguilar (CfA). David Kipping, an astronomer at University College London has devised a new way to accurately measure stars. All it takes is a transiting planet with its own moon, and Keplers laws of motion.. Many exoplanets (planets that orbit stars other than our sun) have been found by using the transit method. Briefly, the planet is directly observed passing in front of its star. If that planet also has a moon, astronomers have the three data points they need to figure out the mass of the star. They can directly measure the orbital periods (time it takes to complete an orbit) of the moon and planet, the size of those orbits relative to the star, and the size of the moon and planet themselves relative to the star. Taken together, these data can be used to determine the size of the star. You need all three objects (star, planet and moon) for this ...
Although Uranus is not the farthest planet from the Sun, it is the coldest planet in the Solar System. Like its neighbor, Neptune, Uranus is an ice giant, meaning it does not have a solid surface and what is called its surface is actually a layer of clouds that lies above what may be a layer of liquid water and a core of rock at the center of the planet. Uranus is 14.5 times bigger than Earth, making it the third largest planet in the Solar System after Jupiter and Saturn; Uranuss core alone is as large as our planet. The atmosphere of Uranus is composed of 83% helium, 15% methane and 2% methane plus trace amounts of other gases such as ethane.. The average temperature of the surface of Uranus is 49° Kelvin or -224° Celsius. What makes the planet so cold is that it has a low internal temperature. At its core, Uranus is only 5000° K, compared to Jupiter, which as a core temperature of 30000° K. The reason for Uranuss lack of internal warmth is unclear, although scientists speculate that ...

Pluto was recently stripped of its planet status by the IAU 9International Astronomical Union), going from a mighty planet to a lowly dwarf planet. The new definition of planet states that not only must it orbit the sun and be large enough to assume a nearly round shape due to gravity, but it also must clear the neighborhood around its orbit. Pluto was disqualified by the last restriction, as its oblong orbit overlaps Neptunes. Many scientist were not happy about the decision though, as many of the other eight planets, including our own, do not pass the three tests with flying colors. The presence of near-Earth objects floating around means that Earth itself has not entirely cleared its orbit neighborhood. It appears that textbook writers and school teachers may make the final decision though, as what they write and teach will be what Americas children learn.. [Scientific American].

Certainly such a picture is a misapprehension of Gaia theory, which though fancifully named is a serious branch of science. Every scientist rankles at undeserved censure from anti-science detractors, but worse is to be mistakenly applauded as a champion of their cause, as Gaia theory sometimes has been. More intriguing to read, however, would be a development of the fascinating ideas Margulis presents in the preceding chapter of Symbiotic Planet, detailing the manner in which symbiosis allowed life to extend its range to dry shores, beyond the nutrient-filled sea where it originated. By gradual collaborations and fusions, life became more and more adapted for carrying its necessary elements to new frontiers. Ever more creative instances of symbiosis went hand in hand with the expansion of ecosystems to cover the whole Earth, resulting in the Gaia phenomenon of a self-regulating, living globe. A symbiotic planet is a homeostatic planet ...

There is an excess of slow rotators among smaller minor planets. The rotation rates were determined mostly by the analysis of lightcurves, which are plots of magnitude versus time. Mathematical (e.g., Fourier) analysis of those data points leads to the determination of the period. It can also show that a minor planet is binary or in non-principal axis rotation (tumbling). In some cases, a carefule review of the rotation period for a given minor planet over the years can show that the minor planets period is changing, getting slower or faster over time.. The formation of binary minor planets, tumbling action, and period change are most likely due to the YORP effect, which is a thermal process where absorbed sunlight, re-radiated as heat, can affect the minor planets rotation period and even spin axis orientation. Another effect, the Yarkovsky (the Y in YORP), can cause the minor planets semi-major axis to increase or decrease.. The shape and spin axis orientation of a minor planet can be ...
Ill tell you what I see: I see a beautiful blue/green planet with a sentient race who selfishly, greedily, does not care for the most part. It is through religion, perhaps (real religion, not whatever you are accusing climate change advocates of), that humans feel they have dominion over the planet and can cut, hack, pollute, contaminate, deplete, make war, drain, re-engineer, the precious land and water all they want. Hey, it is capitalism and that is God, isnt it? So the God of Capitalism and the God of Religion go hand in hand, and the planet is hurt. ...

New radio wave technique could detect alien planets, receive interstellar tunes and because exoplanets often have decades-long orbits, meaning you could spend a lot of lonely nights fruitlessly searching the skies.Scientists at the University of Leicester in England developed a new approach,, they are looking for radio waves emitted when ultraviolet flares light up the atmospheres of planets like Saturn and Jupiter................
The origin of water on our planet is not only of interest for our understanding of the evolution of our own planet and life thereon, but even more so for the increasing exploration of other planets within our solar system and the discovery of potential planetary systems in other galaxies. Having spent half a lifetime teaching his students the accepted versions of the origin of our planetary water, which increasingly did not fit the available evidence, Dr Mike Drake at the University of Arizona suggested an alternative hypothesis: that water was already present at the surfaces of interstellar dust grains when they accreted to form our planet. Although this hypothesis fitted with all available evidence, it would only be feasible if the adhesion of water to the dust grains was sufficiently strong to survive the harsh conditions in the interstellar dust clouds where planets form. Computer simulations by myself and colleagues in UCL, Arizona and Muenster on the adhesion of water to a mineral commonly ...

After the formation of the Solar System, the orbits of all the giant planets continued to change slowly, influenced by their interaction with the large number of remaining planetesimals. After 500-600 million years (about 4 billion years ago) Jupiter and Saturn fell into a 2:1 orbital resonance; Saturn orbited the Sun once for every two Jupiter orbits.[3] This resonance created a gravitational push against the outer planets, causing Neptune to surge past Uranus and plough into the dense planetesimal belt. The planets scattered the majority of the small icy bodies inwards, while themselves moving outwards. These planetesimals then scattered off the next planet they encountered in a similar manner, moving the planets orbits outwards while they moved inwards.[5] This process continued until the planetesimals interacted with Jupiter, whose immense gravity sent them into highly elliptical orbits or even ejected them outright from the Solar System. This caused Jupiter to move slightly inward. This ...

Exactly. Take, for instance, the question about Pluto no longer being considered a planet. I was at the conference where Pluto was demoted, and I still cringe a little when I think of people equating this sort of trivium with scientific literacy. Pluto didnt change, of course: what did was our knowledge of how many objects there are like it, and how those differ from the other planets in our solar system. Those discoveries were interesting, to those of us who care about this sort of thing, partly because of the debate they stirred about how planets are formed, how common different types of planets are, and what ultimately defines a planet as something other than a star or an asteroid or whatever. But the decision to name Pluto a dwarf planet instead of a planet -- what? is dwarf just an adjective? or is dwarf planet its own noun, like planetino or something? -- is, independent of all that context, just not a big deal. And if people get the idea that meaningless labeling is ...
The solar system is made up of the Sun, the planets and dwarf planets and their known moons, asteroids, comets, dust and gas. The planets, asteroids, and comets travel around the Sun, the center of our solar system.. Most of the bodies in the solar system travel around the Sun along nearly circular paths or orbits, and all the planets travel about the Sun in the anticlockwise direction (when viewed from above).. Solar system formation began billions of years ago, when gases and dust began to come together to form the Sun, planets, and other bodies of the solar system.. ...
The Tiny Moon Phobos Is Photographed During Its Quick Trip Around Mars. While photographing Mars, NASAs Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Discovered in 1877, the diminutive, potato-shaped moon is so small that it appears star-like in the Hubble pictures. Phobos orbits Mars in just 7 hours and 39 minutes, which is faster than Mars rotates. The moons orbit is very slowly shrinking, meaning it will eventually shatter under Mars gravitational pull, or crash into the planet. Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the moons orbital path.. ...

Sampling of ocean life is hindered by the extreme cost, limited logistical flexibility, and high carbon footprint of classical oceanographic research vessels. Developing a working understanding of the dynamics and evolution of global plankton will require a far greater sampling effort, increasing coverage across both space and time in the rapidly changing ocean. The new Plankton Planet (P2) program represents a low-cost, eco-friendly, and society engaging Oceanography 2.0, through providing the tools to connect oceanographers to the thousands of blue citizens (seatizens!) who sail across the oceans at any given time. The aim is to undertake a holistic worldwide sampling of plankton life at an unprecedented level of sensitivity, ultimately allowing robust mathematical modeling toward a predictable ocean. We will present our general approach and newly developed imaging tools for bringing citizen sailors closer to enable scientific sampling and engage in the microscopic beauty of the ...
There is the possibility of Liquid Breathing, however it is unlikely that the liquid would be haemoglobin and still be breathable, as haemoglobin is quite viscous (this is why it is contained within red blood cells).. On the other hand, in the unlikely event that a planet was completely covered by an ocean of some largely colourless oxygen saturated liquid such as a flurocarbon at ~37°C, then, yes, humans could in theory breathe this liquid. It is probable that if such a planet existed, it would have been manufactured by some powerful civilisation.. However, free-breathing fluorocarbons is exhausting due to the mass of fluid involved and the amount of oxygen that could be saturated in it. Were humans to spend any length of time in such an environment, it is likely that they would need some sort of mechanical breathing assistance to prevent exhaustion.. Finally, fluorocarbons are up to twice as dense as water. This means that a human would float on the surface of a fluorocarbon sea to a greater ...
Based on the French comic series that inspired Star Wars and other films in the genre, Valerian and the City of a Thousand Planets is a visually rich sci-fi adventure that doesnt have the story or characters to support its excellent world building. The movie is all over the place, jumping from one CG-fueled set piece to the next with a seemingly endless supply of cool creatures and production design - almost too much to cram into one film. Unfortunately, the plot is as dull as dishwater, and though Dane DeHaan and Cara Delevingne fare just fine as the secret agents at the center of the story, their bickering couple shtick isnt as charming as director Luc Besson seems to think. Valerian and the City of a Thousand Planets has some great moments, especially early on, but despite Bessons attempts to deliver the same pulpy fun as his 1997 cult classic The Fifth Element, it falls short.. Extras include a five-part documentary about making the film, a collection of supplemental featurettes ...
