Out in the Kuiper Belt, the massive doughnut of debris beyond Neptune, about one in 10 kilometer-scale objects have surprised scientists with their unexpected shape. Rather than resembling a ball, ...

Planetary systems in the Milky Way galaxy tend to follow a particular pattern: rocky planets toward the center, closest to ...

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 ...

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

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