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

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

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 ...

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

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 ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

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 ...

Space is full of mysteries that can't be easily explained by the layman, and this latest one from a isn't likely to sour anyone on their fascination with space. Scientists from several institutions, ...

WASHINGTON, April 18 (Reuters) - In a memorable image from the 1977 film "Star Wars," the young hero Luke Skywalker gazes at two suns setting above the horizon on his desert planet Tatooine.

Seven planets are aligning in the night sky and will be visible Friday, February 28. The alignment, also called a "planet parade," happens when planets' orbits around the sun cause them to appear ...
