Gliese 581g, the First Exoplanet Found That May Have Been Able to Host Life, Doesn’t Actually Exist

So long Gliese 581g, the potentially habitable exoplanet that never was

This image was taken while exploring a 1300m lava cave in Iceland. In some areas the roof has caved in, so snow piles up in the winter time and creates these snow peaks. The aurora at its peak gleams through the roof of the cave and despite only taking up a small portion of the photo, it remains the focal point.

These Amazing Pictures Made the Shortlist For Astronomy Photographer of the Year

The competition, now in it's sixth year highlights beautiful images of the sky from around the world

The newly discovered "mega-Earth" Kepler-10c dominates the foreground in this artist's conception. Its sibling, the lava world Kepler-10b, is in the background. Both orbit a sunlike star. Kepler-10c has a diameter of about 18,000 miles, 2.3 times as large as Earth, and weighs 17 times as much. Therefore it is all solids, although it may possess a thin atmosphere shown here as wispy clouds.

This Rocky Exoplanet is Really, Really Big—Too Big
