Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

WASHINGTON — Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous neighbors, possibly after ...

A new study hints that Saturn's largest moon, Titan, was created around 400 million years ago, when two massive moons smashed into each other. This hypothesis could also help to solve several other ...

Astronomers have spotted an unusual 'inside-out' planetary system where a rocky world seems to have formed far beyond the realm typically reserved for gas giants.

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four massive but extremely low-density worlds orbiting the star appear to be ...

A team of scientists has found a new planet which orbits the wrong way around its host star. The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK’s WASP project in ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

A Tatooine-like world with a key difference from the desert planet in "Star Wars" has been serendipitously discovered orbiting not two stars, but a pair of brown dwarfs. What's more, this wacky planet ...

The system, observed using the European Space Agency's Cheops space telescope, consists of four planets — two rocky and two ...
