The Latest Breaking News from James Webb Space Telescope

Data from the James Webb Space Telescope indicate that a galaxy known as GN-z11 has a supermassive black hole at its center — one that's far more massive than astronomers expected.

The mysterious wispy green light captured by the James Webb Space Telescope last year near the heart of Cassiopeia A turns out to be a result of a blast wave slamming into surrounding material.

Astronomers using the James Webb Space Telescope have spotted what may be the smallest known brown dwarf, a "failed star" that's only three or four times larger than Jupiter.

The James Webb Space Telescope has observed record-breaking free-floating "failed star" and two other brown dwarfs. The discovery could help scientists better determine where the line between a planet and a star is drawn.

The James Webb Space Telescope has imaged a "Cosmic Christmas Bauble" that is actually the aftermath of a supernova. The stunning picture of Cassiopeia A was revealed by Jill Biden as part of the first-ever White House Advent Calendar.

NASA’s James Webb Space Telescope captures the explosive aftermath of supernova remnant Cassiopeia A in all its infrared splendor.

The James Webb Space Telescope has taken a bite out of a cosmic burger to create a 2D inventory of different forms of ice surrounding a planet-birthing disk.

The James Webb Space Telescope's discovery of water and other molecules in the inner region of a hot protoplanetary disk suggests that rocky, Earth-like planets may be able to form in some very extreme environments.

A ghostlike dusty galaxy from the early universe might represent a whole population of hidden galaxies.
