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 ...

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/ ...

Although the Kepler space telescope already past its expected lifespan, NASA is trying to keep it alive and on its planet-finding mission. NASA's Kepler space telescope has found more than 2,700 ...

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.

If you think it’s hard to be in a stable orbit around one star, think of how hard it must be to maintain an orbit around two. Binary star systems are the most common type of star system we have found.

NASA has discovered a new super-Earth that has a year only lasting a few hours. The exoplanet K2-141b, was found very close to its orange sun-like star, and has an orbital period of less than one ...

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, ...

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 ...

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, ...
