A moon can sit next door to another and still feel like a different world. Around Jupiter, that contrast shows up fast.

Deep below the crust and mantle, far beyond the reach of any drill, Earth’s core may be hiding a planetary-scale cache of hydrogen. Recent high‑pressure experiments suggest that this hidden store ...

We've been watching temperatures climb, extreme weather events intensify, and ice sheets shrink. Every weather forecast and climate projection relies on incredibly complex computer simulations that ...

The arrival of 3I/ATLAS in our solar system spawned multiple proposals for a rendezvous mission to study it up close. As the ...

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

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 ...

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

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

By Will Dunham WASHINGTON, Feb 14 (Reuters) - Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its ...

“It’s all I ever wanted to do,” said Connolly, founding chair and professor in the Department of Geology within the School of Earth & Environment and a research associate in the Department of Earth ...

A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.
