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 ...
Astronomers have found a planetary system that seems to have formed inside-out. While most systems, like our own, have rocky planets closest to their star and gaseous ones further out, the LHS 1903 ...
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, ...

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 ...
