Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, since […]

New NASA NExSS Coalition to Lead Search for Life on Distant Exoplanets

Along with Jupiter’s infamous moon Europa, Saturn’s moon Enceladus is one of the most fascinating places in the Solar System, with its huge geysers of water vapor erupting from cracks […]

Kepler Confirms Over 1,000 Exoplanets, Finds More Potentially Habitable Worlds
