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 ...

Mercury is the smallest planet in our solar system. Explore its size, extreme temperatures, core structure, and comparison with Pluto.

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover ...

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

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 ...

First its rotation slowed between March and May 2017, taking 46 hours to complete a spin where it had once taken only 20 hours. This occurred as the comet neared its closest point to the sun, roughly ...

A distant star has just been caught in the act of destroying one of its own worlds, a violent finale astronomers have long ...

Every once in a while, the mechanics of our solar system grant Earth and its residents a better-than-average view, as is the ...
