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. Eric Mack has been a CNET ...

Two of the earliest Earth-ish exoplanet finds are now more exciting targets in the search for habitable worlds beyond this rock. Eric Mack has been a CNET contributor since 2011. Eric and his family ...

Technicians working inside the Astrotech Space Operations facility near NASA's Kennedy Space Center look over the Kepler spacecraft soon after it arrived in Florida in preparation for launch. [Read ...

NASA scientists used a neural network called ExoMiner to examine data from Kepler, increasing the total tally of confirmed exoplanets in the universe. An artist's concept of exoplanet Kepler-186f.

THE hunt for life in space has taken a step forward with the discovery of “Earth’s cousin” orbiting a distant star. The exoplanet dubbed Kepler-186f was first spotted by scientists using NASA’s Kepler ...

NASA's planet-hunting Kepler space telescope has just spotted Earth's cousin. Its next big find may be Earth's twin. On Thursday (April 17), astronomers announced the discovery of Kepler-186f, the ...

On Earth, plants are green thanks to our Sun’s light—but Kepler-186f orbits a cooler, redder star. Here’s why alien vegetation might evolve with deep red hues instead of green. Trump Warns of Threat ...

Researchers suggest that two Earth-like exoplanets (Kepler-186f and 62f) have very stable axial tilts, much like the Earth, making it likely that each has regular seasons and a stable climate. A new ...
