WASHINGTON, Feb 14 (Reuters) - Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous ...
An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...
Planets are always lined up along the same celestial path, so this “parade” is all about timing Six planets will appear along the same stretch of sky just after this weekend, with the best views ...
Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth. Of the more ...

This is a brilliant question because the notion of an orbit is counterintuitive. We know that massive objects (really, any objects with mass) gravitationally attract other massive objects; Newton’s ...
Most of the exoplanets we’ve discovered have been in relatively tight orbits around their host stars, allowing us to track them as they repeatedly loop around them. But we’ve also discovered a handful ...
Astronomers have detected a rogue planet with a mass equivalent to that of Saturn, and by taking observations from both the ground and space, they have also been able to measure its size and distance ...
Nearly 10,000 light years away, a planet the size of Saturn is floating all on its own through empty space. In a stroke of luck, researchers were able to spot this strange, dark world using both ...
It was almost 100 years ago that Clyde W. Tombaugh discovered Pluto. That was the last planet found until 1992, when humans found another one. But this new planet wasn't in our solar system—it was ...
