Starlight has been the key to finding thousands of exoplanets over the past decade, but researchers have found a new way to ...

Scientists have discovered a 'super–Earth' planet less than 20 light–years away, and it could have the right conditions for alien life. The exoplanet, dubbed GJ 251 c, is at least four times larger ...

Astronomers have discovered 41 new alien planets in one sweep by analyzing how each world gravitationally yanks on its neighbors. The newly confirmed exoplanets were spotted by NASA's prolific Kepler ...

This not-so-little piece of equipment could change astronomy forever. And it could be about to find alien life. Maybe in a ...

Kepler-62f (also known by its Kepler Object of Interest designation KOI-701.04) is a super-Earth exoplanet orbiting within the habitable zone of the star Kepler-62, the outermost of five such planets ...

Planets orbiting stars beyond the solar system come in all shapes and sizes but mostly fit into a few categories: large and hot gas giants, super-Earths that are slightly larger than our planet, ...

Alien solar systems that are home to so-called "hot Jupiters" — gas giants circling sizzlingly close to their stars — are unlikely homes for Earth-like planets, researchers say. Hot Jupiters get their ...

Astronomers have discovered a remarkable planetary system where three very different objects orbit a distant star—and their ...

Searching for alien life by looking for specific signals from individual planets may overlook a larger pattern, new research ...
