Analysis of data from NASA's planet-hunting Kepler space telescope has revealed a near Earth-size world orbiting in the habitable zone of a sun-like star, scientists announced Thursday, the closest ...

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/ ...

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 ...

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.

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 ...

What is Perihelion? In the vast expanse of space, celestial bodies follow elliptical orbits around stars, with one point being closer to the star—known as the perihelion. This is the term used to ...

A new set of images taken by NASA's Kepler Space Telescope shows a faint, pixelated view of TRAPPIST-1, a small, dim star 40 light-years from Earth that plays host to at least seven Earth-sized worlds ...

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 ...
