UV irradiation of polycyclic aromatic hydrocarbons in ices: production of alcohols, quinones, and ethers. (1/70)

Polycyclic aromatic hydrocarbons (PAHs) in water ice were exposed to ultraviolet (UV) radiation under astrophysical conditions, and the products were analyzed by infrared spectroscopy and mass spectrometry. Peripheral carbon atoms were oxidized, producing aromatic alcohols, ketones, and ethers, and reduced, producing partially hydrogenated aromatic hydrocarbons, molecules that account for the interstellar 3.4-micrometer emission feature. These classes of compounds are all present in carbonaceous meteorites. Hydrogen and deuterium atoms exchange readily between the PAHs and the ice, which may explain the deuterium enrichments found in certain meteoritic molecules. This work has important implications for extraterrestrial organics in biogenesis.  (+info)

Condensation of carbon in radioactive supernova gas. (2/70)

Chemistry resulting in the formation of large carbon-bearing molecules and dust in the interior of an expanding supernova was explored, and the equations governing their abundances were solved numerically. Carbon dust condenses from initially gaseous carbon and oxygen atoms because energetic electrons produced by radioactivity in the supernova cause dissociation of the carbon monoxide molecules, which would otherwise form and limit the supply of carbon atoms. The resulting free carbon atoms enable carbon dust to grow faster by carbon association than the rate at which the dust can be destroyed by oxidation. The origin of presolar micrometer-sized carbon solids that are found in meteorites is thereby altered.  (+info)

In search of planets and life around other stars. (3/70)

The discovery of over a dozen low-mass companions to nearby stars has intensified scientific and public interest in a longer term search for habitable planets like our own. However, the nature of the detected companions, and in particular whether they resemble Jupiter in properties and origin, remains undetermined.  (+info)

Black holes in the milky way galaxy. (4/70)

Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4-16 times the mass of the sun, whereas the latter are "supermassive black holes" with millions to billions of solar masses. The evidence for a supermassive black hole in the center of our galaxy is especially strong.  (+info)

Is redshift-dependent evolution of galaxies a theoretical artifact? (5/70)

The physical validity of the hypothesis of (redshift-dependent) luminosity evolution in galaxies is tested by statistical analysis of an intensively studied complete high-redshift sample of normal galaxies. The necessity of the evolution hypothesis in the frame of big-bang cosmology is confirmed at a high level of statistical significance; however, this evolution is quantitatively just as predicted by chronometric cosmology, in which there is no such evolution. Since there is no direct observational means to establish the evolution postulated in big-bang studies of higher-redshift galaxies, and the chronometric predictions involve no adjustable parameters (in contrast to the two in big-bang cosmology), the hypothesized evolution appears from the standpoint of conservative scientific methodology as a possible theoretical artifact.  (+info)

Neutrinos. (6/70)

Neutrinos represent a new "window" to the Universe, spanning a large range of energy. We discuss the science of neutrino astrophysics and focus on two energy regimes. At "lower" energies ( approximately 1 MeV), studies of neutrinos born inside the sun, or produced in interactions of cosmic rays with the atmosphere, have allowed the first incontrovertible evidence that neutrinos have mass. At energies typically one thousand to one million times higher, sources further than the sun (both within the Milky Way and beyond) are expected to produce a flux of particles that can be detected only through neutrinos.  (+info)

Nebular and auroral emission lines of [Cl III] in the optical spectra of planetary nebulae. (7/70)

Electron impact excitation rates in Cl III, recently determined with the R-matrix code, are used to calculate electron temperature (T(e)) and density (N(e)) emission line ratios involving both the nebular (5517.7, 5537.9 A) and auroral (8433.9, 8480.9, 8500.0 A) transitions. A comparison of these results with observational data for a sample of planetary nebulae, obtained with the Hamilton Echelle Spectrograph on the 3-m Shane Telescope, reveals that the R(1) = I(5518 A)/I(5538 A) intensity ratio provides estimates of N(e) in excellent agreement with the values derived from other line ratios in the echelle spectra. This agreement indicates that R(1) is a reliable density diagnostic for planetary nebulae, and it also provides observational support for the accuracy of the atomic data adopted in the line ratio calculations. However the [Cl iii] 8433.9 A line is found to be frequently blended with a weak telluric emission feature, although in those instances when the [Cl iii] intensity may be reliably measured, it provides accurate determinations of T(e) when ratioed against the sum of the 5518 and 5538 A line fluxes. Similarly, the 8500.0 A line, previously believed to be free of contamination by the Earth's atmosphere, is also shown to be generally blended with a weak telluric emission feature. The [Cl iii] transition at 8480.9 A is found to be blended with the He i 8480.7 A line, except in planetary nebulae that show a relatively weak He i spectrum, where it also provides reliable estimates of T(e) when ratioed against the nebular lines. Finally, the diagnostic potential of the near-UV [Cl iii] lines at 3344 and 3354 A is briefly discussed.  (+info)

Titanium carbide nanocrystals in circumstellar environments. (8/70)

Meteorites contain micrometer-sized graphite grains with embedded titanium carbide grains. Although isotopic analysis identifies asymptotic giant branch stars as the birth sites of these grains, there is no direct observational identification of these grains in astronomical sources. We report that infrared wavelength spectra of gas-phase titanium carbide nanocrystals derived in the laboratory show a prominent feature at a wavelength of 20.1 micrometers, which compares well to a similar feature in observed spectra of postasymptotic giant branch stars. It is concluded that titanium carbide forms during a short (approximately 100 years) phase of catastrophic mass loss (>0.001 solar masses per year) in dying, low-mass stars.  (+info)

Now that you have some feeling for the scales of time and space that astronomy encompasses and some of the difficulties caused by being Earth-bound (well, okay: solar-system bound!), lets take a look at what is up there in the sky beyond the clouds. In this chapter, you will learn where to find the key points on the night sky, how to use the coordinate system that astronomers use, how the Suns position among the stars changes and how that affects the temperature throughout the year, and about the phases of the Moon and eclipses. At the end of chapter, you will learn about the motions of the planets among the stars. All of the things in this chapter, you can observe without a telescope---naked eye astronomy (note to Jesse Helms and Sen. Exon: that means astronomy without the use of a telescope). You just need to observe the objects carefully and notice how things change over time. The vocabulary terms are in boldface. ...
The History and Practice of Ancient Astronomy combines new scholarship with hands-on science to bring readers into direct contact with the work of ancient astronomers. While tracing ideas from ancient Babylon to sixteenth-century Europe, the book places its greatest emphasis on the Greek period, when astronomers developed the geometric and philosophical ideas that have determined the subsequent character of Western astronomy. The author approaches this history through the concrete details of ancient astronomical practice. Carefully organized and generously illustrated, the book can teach readers how to do real astronomy using the methods of ancient astronomers. For example, readers will learn to predict the next retrograde motion of Jupiter using either the arithmetical methods of the Babylonians or the geometric methods of Ptolemy. They will learn how to use an astrolabe and how to design sundials using Greek and Roman techniques. The book also contains supplementary exercises and patterns for making

Ahmed Zewali, winner of the Nobel Prize in Chemistry (1999).. Although we live in a world faced with the many immediate problems of hunger, poverty, energy and global warming, we argue that astronomy has long term benefits that are equally as important to a civilized society. Several studies (see below) have told us that investing in science education, research and technology provides a great return - not only economically, but culturally and indirectly for the population in general - and has helped countries to face and overcome crises. The scientific and technological development of a country or region is closely linked to its human development index - a statistic that is a measure of life expectancy, education and income (Truman, 1949).. There are other works that have contributed to answering the question Why is astronomy important? Dr. Robert Aitken, director of Lick Observatory, shows us that even in 1933 there was a need to justify our science, in his paper entitled The Use of Astronomy ...

My name is Fraser Cain, Im the publisher of Universe Today, and with me is Dr. Pamela Gay, a professor at Southern Illinois University Edwardsville. Hi Pamela, howre you doing?. Pamela: Im doing well. How are you doing?. Fraser: Excellent, as usual. Alright, so everything in the universe is spinning. In fact, without this rotation, life on Earth wouldnt even exist. We need the conservation of angular momentum to flatten out galaxies and solar systems, and to make planets possible. Lets find out about the physics involved in everything that spins and finally figure out the difference between centripetal and centrifugal force. Man, there is nothing that makes physics geeks madder than to misuse centrifugal and centripetal force. Honestly, I ...

Radio frequency interference (RFI) is the long-time period nemesis of radio astronomers. Jodrell Financial institution - the earliest radio astronomy observatory in the environment still in existence - was developed because of RFI. Sir Bernard Lovell, 1 of the pioneers of radio astronomy, discovered his perform at Manchester hampered by RFI from passing trams in the city, and he persuaded the universitys botany division to enable him transfer to their fields in Cheshire for two months (he in no way left).. Since then, radio telescopes have been developed additional and much more remotely in an try to avoid RFI, with the impending Sq. Kilometre Array (SKA) telescope currently being constructed across remote places of South Africa and Australia. This can help to minimize out many widespread sources for RFI, which includes cell telephones and microwave ovens. Having said that, ground-based mostly radio telescopes are unable to wholly keep away from space-based resources of RFI this sort of as ...

I had already been working on the SOFIA project for some years, when back in 1998, a consortium of German research institutes (Max-Planck Institute of Radio Astronomy in Bonn, University of Cologne, Max-Planck Institute of Solar System Research and the DLR Institute of Planetary Research) decided to develop the German Receiver for Astronomy at Terahertz Frequencies (GREAT) as the Principal Investigator-class Science Instrument for the first generation at the SOFIA Observatory. At this time, the aim was for the observatory to be operational by the end of 2001. It was not only the optimists who were expecting the GREAT spectrometer to soon enter operational service. Back then, who could have thought that it would take 13 years for GREAT to fly on SOFIA for the first time?

As in many other sciences, the balance between theoretical and instrumental radio astronomy has tended to evolve in cycles. The previous great instrumental revolution, prompted by the invention of the selfcal algorithm in the early 1980s, led to a blossoming of techniques, and the emergence of popular data reduction packages such as AIPS and Miriad. These have proven to be so capable that radio astronomy has lived off that success for the next two decades, with further practical advances being incremental rather than revolutionary.. Over the past several years, the demand for radical new techniques has grown sharply, with a glut of new-generation radio telescopes (ALMA, LOFAR, MeerKAT, PAPER, MWA, ASKAP) being built with a few years of one another, coupled with significant upgrades to older observatories (EVLA, e-MERLIN, Apertif), and with the SKA itself looming large on the horizon. Novel telescopes present new instrumental problems, which the techniques of the 80s can no longer address. ...
Solar astronomy suffers from the same kind of atmospheric distortions that night time astronomy suffers from. To make allowances and correct for the distortions, adaptive optics is used which use computers to take into account the distortions and make telescopic corrections, giving an image as close as possible to the diffraction limit.

In early times, astronomy was related with the observation of the motions of objects visible to the naked eye. All ancient cultures such Chinese Egyptian and Greek civilization had myths and stories about universe creation.The Greeks was not the first culture with universe predictions and observations but their philosophers was widely distributed by the Romans ans consequently for hundreds of years. Eratosthenes of Cyrene ( c.276BC-c.195BC) measured the circumference of the earth to within 3000 Km and Aristarchus of Samos (310BCE-ca.230BCE) first stated that earth revolves around the sun. There were also some cultures which used some structures like ancient calendars but we know little about this. Modern astronomy dates in Europe in about 1300 AD ...

We studied 14 presolar SiC mainstream grains for C-, Si-, and S-isotopic compositions and S elemental abundances. Ten grains have low levels of S contamination and CI chondrite-normalized S/Si ratios between 2 × 10−5 and 2 × 10−4. All grains have S-isotopic compositions compatible within 2σ of solar values. Their mean S isotope composition deviates from solar by at most a few percent, and is consistent with values observed for the carbon star IRC+10216, believed to be a representative source star of the grains, and the interstellar medium. The isotopic data are also consistent with stellar model predictions of low-mass asymptotic giant branch (AGB) stars. In a δ33S versus δ34S plot the data fit along a line with a slope of 1.8 ± 0.7, suggesting imprints from galactic chemical evolution. The observed S abundances are lower than expected from equilibrium condensation of CaS in solid solution with SiC under pressure and temperature conditions inferred from the abundances of more ...
Neutrino astronomy is the branch of astronomy that observes astronomical objects with neutrino detectors in special observatories. Neutrinos are created as a result of certain types of radioactive decay, or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. Due to their weak interactions with matter, neutrinos offer a unique opportunity to observe processes that are inaccessible to optical telescopes. Neutrinos were first recorded in 1956 by Clyde Cowan and Frederick Reines from a nuclear reactor. Their discovery was acknowledged with a Nobel Prize for physics in 1995. In 1968, Raymond Davis, Jr. and John N. Bahcall successfully detected the first solar neutrinos in the Homestake experiment. Davis, along with Japanese physicist Masatoshi Koshiba were jointly awarded half of the 2002 Nobel Prize in Physics for pioneering contributions to astrophysics, in particular for the detection of cosmic neutrinos (the other half went to Riccardo ...

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 ...

N2 - Millimeter-wave observations of PN, CP, and HCP have been carried out toward circumstellar envelopes of evolved stars using the Arizona Radio Observatory (ARO). HCP and PN have been identified in the carbon-rich source CRL 2688 via observations at 1 mm using the Submillimeter Telescope (SMT) and 2-3 mm with the Kitt Peak 12 m. An identical set of measurements were carried out toward IRC +10216, as well as observations of CP at 1 mm. PN was also observed toward VY Canis Majoris (VY CMa), an oxygen-rich supergiant star. The PN and HCP line profiles in CRL 2688 and IRC +10216 are roughly flat topped, indicating unresolved, optically thin emission; CP, in contrast, has a distinct U shape in IRC +10216. ...
In the interstellar medium - the space between the stars in galaxies - new stars are born from material that is replenished by the debris ejected by stars when they die. This book is a comprehensive manual for studying the collisional and radiative processes observed in the interstellar medium. This second edition has been thoroughly updated and extended to cover related topics in radiation theory. It considers the chemistry of the interstellar medium both at the present epoch and in the early Universe, and discusses the physics and chemistry of shock waves. The methods of calculation of the rates of collisional excitation of interstellar molecules and atoms are explained, emphasising the quantum mechanical method. This book will be ideal for researchers involved in the interstellar medium and star formation, and physical chemists specialising in collision theory or in the measurement of the rates of collision processes.. • Comprehensive manual for studying collisional and radiative processes ...

The interplay between inflows and outflows of gas around galaxies has wide-ranging implications for galaxy evolution. We present results for a serendipitous background / foreground galaxy pair based on HST/WFC3 imaging, Keck/HIRES spectroscopy, and GALEX--Spitzer/IRAC photometry. The background galaxy is a massive (stellar mass 1011 solar masses) post-starburst galaxy at z=0.71 with an extremely compact morphology (effective radius 0.15 kpc) and an extreme outflow (velocity -2500 km/s) traced by Mg I, Mg II, Fe II, and Mn II absorption lines. The depth of the Mg II absorption lines show that the outflowing gas covers the entire galaxy at v -2500 km/s with additional optically thick, smaller covering factor gas extending to -3000 km/s. These results suggest a picture where a recent, highly dissipative merger event formed a compact starburst that launched an energetic, galaxy-wide outflow. The foreground object is an L* disk galaxy at z=0.41 for which we detect Mg II and Fe II absorption lines at ...

ADC_Keywords: Stars, S ; Mass loss ; Masers ; Photometry, infrared Keywords: stars: mass-loss - stars: AGB - stars: late-type - infrared: stars - radio lines: stars Abstract: It is the purpose of this paper to rediscuss the circumstellar properties of S stars and to put these properties in perspective with our current understanding of the evolutionary status of S stars, in particular the intrinsic/extrinsic dichotomy. This dichotomy states that only Tc-rich (intrinsic) S stars are genuine thermally-pulsing asymptotic giant branch stars, possibly involved in the M-S-C evolutionary sequence. Tc-poor S stars are referred to as extrinsic S stars, because they are the cooler analogs of barium stars, and like them, owe their chemical peculiarities to mass transfer across their binary system. Accordingly, an extensive data set probing the circumstellar environment of S stars (IRAS flux densities, maser emission, CO rotational lines) has been collected and critically evaluated. This data set ...
A team of astronomers has used the High Dispersion Spectrograph on the Subaru Telescope to conduct spectroscopic observations of Sun-like superflare stars first observed and cataloged by the Kepler Space Telescope. The investigations focused on the detailed properties of these stars and confirmed that Sun-like stars with large starspots can experience superflares. The team, made up of astronomers from Kyoto University, University of Hyogo, the National Astronomical Observatory of Japan (NAOJ), and Nagoya University, targeted a set of solar-type stars emitting very large flares that release total energies 10-10000 times greater than the biggest solar flares. Solar flares are energetic explosions in the solar atmosphere and are thought to occur by intense releases of magnetic energy around the sunspots. Large flares often cause massive bursts of high-speed plasma called coronal mass ejections (CMEs), can lead to geomagnetic storms on Earth. Such storms can have severe impacts on our daily life by

NASA has released the first image from the Juno spacecraft since its arrival at Jupiter last week. This colour view of the gas giant and its moons was taken by the JunoCam imaging camera after the spacecraft entered orbit on 5 July (UTC). It confirms that JunoCam survived its first pass through Jupiters extreme radiation environment, and is ready to collect further images.. The image was taken on 10 July 2016 at 0530 UTC, when the spacecraft was 4.3 million kilometres (2.7 million miles) from Jupiter on the outbound leg of its initial 53.5-day capture orbit. The image shows atmospheric features on Jupiter, including the Great Red Spot, and three of Jupiters four largest moons which have been labeled here.. JunoCam will continue to image Jupiter during Junos capture orbits. The first high-resolution images of the planet will be taken on 27 August when the Juno spacecraft makes its next close pass to Jupiter.. ...
Recent discoveries by the Kepler space telescope and others indicate exoplanets are commonplace across the Milky Way and, by extension, the universe. With uncounted billions of planets presumed to exist, physicist Enrico Fermis famous question regarding the existence of aliens is more glaring than ever: Where are they?. That is, I think, one of the amazing discoveries of the last century or so - that planets are common, said Philip Lubin, an experimental cosmologist and professor of physics at the University of California at Santa Barbara.. If planets are commonplace, and if many of those worlds orbit in their stars habitable zones where water - and life - can, in theory exist, statistics alone would indicate life on other worlds is at least possible if not likely.. Given the lack of any such evidence to date, Lubin is heading up a mostly student-run survey to look for signs of continuous-wave laser transmissions - directed energy signatures - originating in the Andromeda galaxy. The ...

An intermediate-mass black hole (IMBH) is a hypothetical class of black hole with mass in the range 100 to one million[citation needed] solar masses: significantly more than stellar black holes but less than supermassive black holes. There is as yet no unambiguous detection of an IMBH, but the indirect evidence from various directions is promising. The strongest evidence for IMBHs comes from a few low-luminosity active galactic nuclei. Due to their activity, these galaxies almost certainly contain accreting black holes, and in some case the black hole masses can be estimated using the technique of reverberation mapping. For instance, the spiral galaxy NGC 4395 at a distance of about 4 Mpc appears to contain a black hole with mass of about 3.6×105 solar masses.[relevant? - discuss] Some ultra-luminous X ray sources (ULXs) in nearby galaxies are suspected to be IMBHs, with masses of a hundred to a thousand solar masses. The ULXs are observed in star-forming regions (e.g., in starburst galaxy ...
Effective collecting area, angular resolution, field of view and energy response are fundamental attributes of X-ray telescopes. The performance of state-of-the-art telescopes is currently restricted by Wolter optics, especially for hard X-rays. Here we report the development of a stacked prism lens (SPL), which is lightweight and modular and has the potential for a significant improvement in effective area, while retaining high angular resolution. The proposed optics are built by stacking disks embedded with prismatic rings, created with photoresist by focused ultraviolet lithography. We demonstrate the SPL approach using a prototype lens that was manufactured and characterized at a synchrotron radiation facility. The design of a potential satellite-borne X-ray telescope is outlined and the performance is compared with contemporary missions. A stacked series of lithographed polymer disks could provide a lightweight and modular optics system for a future hard X-ray telescope, retaining the angular
Planetary magnetic fields are ubiquitous in the Solar System and extrasolar planets are common in the galaxy. However, no extrasolar planetary magnetic field (or exodynamo) has yet been directly detected. Magnetic fields offer a unique window into the internal structure and dynamics of planets, can be remotely detected by electron cyclotron emission at radio wavelengths, and are commonly assumed to be important for surface habitability. In this talk we describe the conditions necessary for the generation of magnetic fields in the cores of terrestrial exoplanets, how they might evolve over time, and the important role of internal heat sources. We demonstrate that eccentric Earth-mass planets in the habitable zone around M dwarfs are likely to be within the tidal zone, where gravitational tidal dissipation can be extreme, prolonging the magma ocean phase and inhibiting dynamo action. ...

A moon was discovered orbiting the asteroid, Eugenia. This is only the second time in history that a satellite has been seen circling an asteroid. A special mirror allowed scientists to find the moon from a telescope on Earth. The mirror corrects for the blurring caused by Earths atmosphere. This effect is called adaptive optics. The Hubble Telescope was originally launched so scientists could see objects without looking through the atmosphere. Now, they can study objects from Earth as well. Making this discovery with the newly developed adaptive optics moves ground-based astronomy to the forefront in exploring neighboring objects in our solar system, said Vernon Pankonin, manager of NSFs planetary astronomy program. Asteroid satellites are very difficult to find. The first one, called Dactyl, was discovered by the Galileo spacecraft in 1993. It orbits the asteroid Ida. Eugenias moon was even harder to find, because the asteroid is much brighter than its moon. Its like looking for a ...

If something cant be detected, can we actually say it exists? This was the conundrum facing Wolfgang Pauli when he proposed that a neutral particle (i.e. the neutrino) is emitted in the beta decay of a nucleus.. While it solved some profound mysteries, it was soon suggested that such a particle would be impossible to detect. Nearly a century later, we not only have detected neutrinos, but understand that they come in three species, have antimatter counterparts, and that they play a crucial role as fundamental building blocks of the Universe and in determining its structure. I will discuss how neutrino oscillations, the discovery of which was awarded this years Nobel Prize have uncovered some of its fundamental properties (such as the fact that it has a tiny but non-zero mass). Befitting its history, these studies have answered some questions about neutrinos but the answers are bizarre and raise new questions. In the near future, we hope to understand the relationship between the neutrino and ...
Supernova Sonata by Alex Parker From April, 2003 until August, 2006, the Canada-France-Hawaii Telescope watched four parts of the sky as often as possible. Armed with the largest digital camera in the known universe, CFHT monitored these four fields for a special type of supernova (called Type Ia) which are created by the thermonuclear detonation of one or more white-dwarf stars. Each supernova is assigned a note to be played: The volume of the note is determined by the distance to the supernova, with more distant supernova being quieter and fainter. The pitch of the note was determined by the supernovas stretch, a property of how the supernova brightens and fades. Higher stretch values played higher notes. The pitches were drawn from a Phrygian dominant scale. The instrument the note was played on was determined by the properties of the galaxy which hosted each supernova. Supernovae hosted by massive galaxies are played with a stand-up bass, while supernovae hosted by less massive galaxies ...

This movie [at right] records an eruptive event in the southern hemisphere of Jupiter over a period of 8 Jupiter days. Prior to the event, an undistinguished oval cloud mass cruised through the turbulent atmosphere. The eruption occurs over a very short time at the very center of the cloud. The white eruptive material is swirled about by the internal wind patterns of the cloud. As a result of the eruption, the cloud then becomes a type of feature seen elsewhere on Jupiter known as spaghetti bowls.[49]. As Voyager 2 approached Jupiter in 1979, it took images of the planet at regular intervals. This sequence is made from 8 images taken once every Jupiter rotation period (about 10 hours). These images were acquired in the Violet filter around May 6, 1979. The spacecraft was about 50 million kilometers from Jupiter at that time.[49]. At left is a Voyager 1 image showing Jupiter with its satellite Io visible at lower left. Jupiter is 140,000 km in diameter and Io is 3600 km across. This image ...

One of the main scientific objectives of the recent Fermi mission is unveiling the nature of the unidentified gamma-ray sources (UGSs). Despite the large improvements of Fermi in the gamma-ray source localization with respect to the past gamma-ray missions, about 1/3 of the Fermi detected objects still do not have yet a low energy counterpart associated. Recently, we discovered that blazars, the rarest and the most gamma-ray detected class of Active Galactic Nuclei, can be recognized and separated from other extragalactic sources using the IR colors. This discovery has been found thanks to the all-sky survey of the recent NASA mission: Wide-field Infrared Survey Explorer (WISE). Consequently, we built an association method for the gamma-ray sources able to recognize if there is a blazar candidate within the positional error region of a generic gamma-ray source. With this new IR diagnostic tool, we searched for blazar candidates within the UGS sample of the second Fermi gamma-ray catalog (2FGL). ...
