In a distant solar system, water-soaked chunks of rock that contain two of the key elements of a habitable planet have been spotted for the first time.
The space agency is giving up on restoring its planet-hunting spacecraft to full operational capability, but that doesn't mean the mission is over just yet.
European astronomers discover the closest-known exoplanet found so far, and it comes with a few surprises. Like, it's a little warmer than our planet.
In a long-awaited milestone, astronomers using a NASA space telescope have found a roughly Earth-size world, Kepler-22b, orbiting around a sun-like star where conditions may be favorable for life.
How close are we to finding alien life? CNET contributor Boonsri Dickinson visits Geoff Marcy's lab at the University of California at Berkeley to hunt for Earth-like planets. Using the Keck telescope in Hawaii and data from the Kepler telescope, Marcy can detect planets millions of miles away.
A Friday evening launch will send the Kepler spacecraft out into the Milky Way on a mission to discover places that might support life as we know it.
Some suns gobble up the planets revolving around them, creating unique chemical signatures that could help astronomers in their planetary hunt.
New Kurzgesagt video tells us everything we need to know about Earth, from how it survived colliding with an object as big as Mars to how it came to support life.
Researchers believe they've found the first rocky, Earth-like exoplanet to orbit a distant binary star system. That's good news for the search for habitable worlds, not to mention real-life analogs to the "Star Wars" universe.
Kepler-186f orbits an M dwarf star in the constellation Cygnus. More importantly, it's the first confirmed Earth-size, potentially habitable planet elsewhere in the universe.
