Its orbit around the host star is at a similar distance to Earth's orbit around our Sun, so it receives a similar amount of energy from the star as the Earth receives from the Sun - increasing the probability of it being habitable. (astronomy.com)
The longer orbit of the new planet means that its climate and atmosphere may be just right to support life," said Hugh Jones from the University of Hertfordshire. (astronomy.com)

This work contributes to our understanding of how the atmospheres of rocky planets orbiting low-mass stars can withstand their strong stellar winds and intense ultraviolett radiation. (mpg.de)
The nearby Trappist-1 planetary system is currently the best candidate to study the atmospheres of rocky, Earth-like planets orbiting a red dwarf star," says Sebastian Zieba, a student at the Max Planck Institute for Astronomy. (mpg.de)
Although relatively cool on the outside, many such stars exhibit strong stellar winds and intense ultraviolett radiation over an extended period of their lifetime, potentially damaging and eroding their planets' atmospheres. (mpg.de)
However, the task of characterizing the atmospheres of rocky, Earth-sized planets is a challenging endeavour, even for the James Webb Space Telescope. (mpg.de)
Set to launch in 2018, JWST will have unprecedented power to detect the atmospheres of faraway planets for biosignature gases that would suggest they host living, breathing organisms. (newscientist.com)

The middle planet, Wolf 1061c, sits within the 'Goldilocks' zone where it might be possible for liquid water - and maybe even life - to exist,' Dr Wright said. (smh.com.au)
A Goldilocks zone is a planet that falls within a star's habitable zone, and the name is often specifically used for planets close to the size of Earth. (crystalinks.com)
Likewise, a planet following this Goldilocks Principle is one that is neither too close nor too far from a star to rule out liquid water on its surface and thus life (as humans understand it) on the planet. (crystalinks.com)
However, planets within a habitable zone that are unlikely to host life (e.g., gas giants) may also be called Goldilocks planets. (crystalinks.com)
The best example of a Goldilocks planet is the Earth itself. (crystalinks.com)
The discovery of extrasolar Goldilocks planets helps to refine estimates for this figure. (crystalinks.com)
High estimates would reinforce the Copernican mediocrity principle, in that large numbers of Goldilocks planets would imply that Earth is not especially exceptional. (crystalinks.com)
Three of Trappist-1's seven planets are in the Goldilocks "habitable zone," neither too close nor too far from their star, permitting the right temperatures for liquid water to exist on their surface. (crystalinks.com)
The planets in the image are in the 'habitable' or 'Goldilocks' zone, which is a belt around a star where temperatures are ideal for liquid water to pool on a planet's surface - and support life. (dailymail.co.uk)
If they're in the Goldilocks zone, Earth-like planets receive the right amount of energy to keep water in the liquid state on the surface (or in our extension, below the surface). (yahoo.com)
It's a very useful tool for picking out planets where life might potentially survive.We are absolutely not dismissing the traditional idea of Goldilocks zones, as some have reported. (yahoo.com)

Gliese 581d "is probably too massive to be made only of rocky material, but we can speculate that it is an icy planet that has migrated closer to the star," according to Stephane Udry , an astronomer with the University of Geneva 's Geneva Observatory and a member of the research team.

Stéphane Udry of the Geneva Observatory in Switzerland and his colleagues spotted the planet by detecting wobbles in the parent star, caused by the orbiting planet's gravity. (bioedonline.org)
The technique used by Udry's team can only put a lower limit on the planet's likely mass, and its size can therefore only be guessed at: if the planet is rocky and Earth-like, its radius should be around 1.5 that of Earth. (bioedonline.org)

The system was previously thought to contain three planets in orbits too close to the star to support liquid water. (astronomy.com)
This significantly increased our sensitivity and enabled us to reveal three new super-Earth planets around the star known as HD 40307, making it into a six-planet system. (astronomy.com)
The star HD 40307 is a perfectly quiet old dwarf star, so there is no reason why such a planet could not sustain an Earth-like climate," said Guillem Angla-Escude from the University of Goettingen, Germany. (astronomy.com)

At 130 trillion kilometres it might sound impossibly distant, but Wolf 1061 in the constellation Ophiucus is the 35th closest star to Earth. (smh.com.au)
The University of NSW team, led by Duncan Wright, said three planets are orbiting Wolf 1061, a red dwarf 'M-type' star. (smh.com.au)
Of the three planets, one is too close to the star and hence too hot for life, and the other is too far out, and hence too cold. (smh.com.au)
Given how close the planet is to the star it is likely to be 'tidally locked',' Dr Wright told Fairfax Media. (smh.com.au)
These small movements create a doppler shift in the light reaching Earth depending on whether the star is moving towards or away from us. (smh.com.au)
They are able to tell the number of objects, their distance from the star, as well as their estimated mass and orbital period. (smh.com.au)
The next step will be for telescopes to look at Wolf 1061 and search for 'transits' of the planets in front of the star. (smh.com.au)
The small dip in light caused by the planets passing in front of the star will allow scientists to find out more about this planetary system. (smh.com.au)
The close proximity of the planets around Wolf 1061 means there is a good chance these planets may pass across the face of the star. (smh.com.au)

The planet is tidally locked to the star, meaning that one side is always facing the star and basking in perpetual daylight, while the side facing away from the star is in perpetual darkness. (scienceblog.com)
These planets are generally hotter than Earth, although some could be of a similar temperature (and therefore habitable) if they're orbiting a cool star called a red dwarf. (scitechdaily.com)
Dr Yock explains that this reflects the difficulty of detecting from a distance a tiny non-luminous object like Earth orbiting a bright object like the Sun. The planet is lost in the glare of the star, so indirect methods of detection must be used. (scitechdaily.com)
A planet is also influenced by the star it orbits. (syfy.com)

However, Hill-stable planetary systems may eventually manifest Lagrange instability when the outer planet escapes or the inner planet collides with the star. (lu.se)
We show empirically that for two nearly coplanar Hill-stable planets with eccentricities less than about 0.3, instability can manifest itself only after a time corresponding to x initial orbits of the inner planet, where log10 x ~ 5.2[μ/(MJupiter/M☉)]-0.18 and μ is the planet-star mass ratio.

Observations taken with Hubble's Cosmic Origins Spectrograph (COS) suggest powerful stellar winds are sweeping the cast-off atmospheric material behind the scorched planet and shaping it into a comet-like tail. (space.com)
