Astronomers photographed a baby planet, WISPIT 2b, during its formation process within a dusty ring around its star system.

A new paper led by a York University professor and published today in Nature Astronomy introduces a simple theoretical framework to describe the evolution of the coupled interior–atmosphere system of ...

Scientists measure a Saturn-sized rogue planet drifting through the Milky Way using rare Earth and space observations, revealing how planets can be ejected from their original systems.
