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 ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that ...

Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

The planets are visible throughout February, "but they’ll be lined up best toward the end of the month,” NASA says.

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 ...

The curious minds at What If investigate the cosmic chaos if Venus and Mars suddenly swapped orbits, revealing the dramatic effects on climate, gravity, and planetary ecosystems.

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 ...

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 newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Could we prevent in-orbit crashes in the future by using advanced computer models?

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...
