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 ...

The artist's concept depicts Kepler-186f , the first validated Earth-size planet to orbit a distant star in the habitable zone—a range of distance from a star where liquid water might pool on the ...

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 ...

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 ...

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 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 diagram compares the planets of the inner solar system to Kepler-186, a five-planet system about 500 light-years from Earth in the constellation Cygnus. The five planets of Kepler-186 orbit a star ...

NASA’s Kepler spacecraft has discovered a “cousin” of Earth 1,400 light-years away. The exoplanet Kepler 452b orbits a sunlike star at about the same distance as Earth orbits the sun, scientists ...

Kepler-186 and the Solar System: The diagram compares the planets of the inner solar system to Kepler-186, a five-planet system about 500 light-years from Earth in the constellation Cygnus. The five ...
