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 ...

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/ ...

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, ...

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 ...

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.

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 ...

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 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 ...

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 ...
