What planet is most like Earth? Reseachers have identified several exoplanets similar to our planet, but none that are an ...

Pluribus imagines Kepler-22b as an ocean world that sends a gift to humanity through radio waves. In real life, no such ...

The discovery of a planet orbiting a binary star in the habitable zone is the tenth of its kind, indicating such planets are more common than previously thought. Michelle Starr is CNET's science ...

Spotting new exoplanets with NASA's Kepler space telescope is nothing new. Google even managed to automate the process with machine learning. Just add them to the pile with the 3,700 other exoplanets, ...

A huge "super-Earth" with an extreme climate that results in it being habitable for only part of its orbit has been discovered orbiting a star 2,472 light years away. And the most remarkable thing is, ...

NASA's Kepler telescope has discovered a planet that orbits two suns, just like Luke Skywalker's homeworld of Tatooine. Luke Westaway Senior editor Luke Westaway is a senior editor at CNET and writer/ ...

Planets that orbit two stars have traditionally been difficult to detect. Despite decades of suspicion, we didn't even spot our first one until 2011 and even now their irregular orbits make life ...

NASA’s Kepler mission confirmed the discovery of its first rocky planet, named Kepler-10b. Measuring 1.4 times the size of Earth, it is the smallest planet ever discovered outside our solar system.

NASA's Kepler planet-hunting probe has spotted a system where two giant planets are locked in constantly changing orbits — with a super-Earth potentially pinned down in the crossfire. Astronomers like ...

The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...
