Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile, one half of ...

Astronomers have recently uncovered a remarkable planetary system around the faint orange star WASP-132, featuring two exoplanets that couldn’t be more different. One is a rocky world that completes ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the ...

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.

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

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 ...

WASHINGTON (Reuters) -Astronomers have spotted a small rocky planet that orbits perilously close to its host star disintegrating as its surface is vaporized by stellar heat, trailed by a comet-like ...
