Watch a physicist explain how a 'Star Trek: Generations' scene violates the laws of physics.

Researchers have identified new details about the size and appearance of the North Star, also known as Polaris

A planet that should have been stripped to bare rock by its nearby host star's intense radiation somehow grew a puffy atmosphere instead.

If confirmed as a galaxy, a newly identified star system would be the faintest ever discovered—and could suggest there are others that remain to be found.

"This star provides a unique window into the very early element-forming process in galaxies other than our own."

New research may better explain the "string of pearls" around the remnant of a star, shedding light on a longstanding astrophysical mystery.

"With unprecedented glimpses into these disks surrounding young stars, the birthplaces of planets, JWST helps us uncover how planets form."

"Fast radio bursts are one of astronomy's greatest mysteries." New research uncovers some clues about their potential origins.

Astronomers have captured close-up images of a massive star, RW Cephei, that experienced a strange fading event.
