The images span 13.5 billion years—98% of the universe’s history—in one region of the sky.

Auroras on Jupiter are hundreds of times brighter and much more variable than previously thought.

The space telescope detected the biosignature twice in the atmosphere of the exoplanet, which orbits a red dwarf star in the habitable zone.

This time, astronomers are actually hopeful for the impact.

The new image reveals a blend of outflows from the forming star Herbig-Haro 49/50 and a distant galaxy hidden far behind it.

Observations from the James Webb Telescope have revealed a peculiar trend. Many of the galaxies surrounding us are rotating in the same direction.

NASA’s SPHEREx telescope will observe more than 450 million galaxies, complementing the James Webb Telescope and providing clues about what to observe.

This phenomenon is marked by a constant flickering and a series of intense but random bursts of brightness that act like a disco ball.

Messier 104 (M104) earned its nickname, the Sombrero Galaxy, because of its unique shape: A bright central nucleus surrounded by a thick disk of matter that resembles the brim of a sombrero.

The James Webb Space Telescope instruments can reach some of the farthest corners of the universe in space and time. Occasionally, however, they target places closer to Earth.

The first galaxies in the universe seemed to be more massive than we expected.

The James Webb Space Telescope has pierced through the cosmic dust of Messier 106, one of the most active nearby galaxies.
