On Earth, plants reflect green light — but on Kepler-186f, they’d likely glow deep red. The reason lies in physics: cooler ...

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 ...

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 ...

New evidence has surfaced suggesting that exoplanet Kepler-186f could have changing seasons and a climate, much like Earth — a discovery that’s exciting astronomers and leading to calls for newer, ...

Scientists analyzing data from the planet-hunting Kepler space telescope have chalked up another first, finding an Earth-size world orbiting in the habitable zone of its parent star, researchers ...

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 ...

A new study from the Georgia Institute of Technology provides new clues indicating that an exoplanet 500 light-years away is much like Earth. Kepler-186f is the first identified Earth-sized planet ...
