An explosive flare from the Milky Way's central black hole has been translated from 'a single flickering pixel' into a detailed 3D model using AI and Einstein's general relativity equations.

The Helix Galaxy is a rare "polar ring" galaxy found near the Big Dipper. Its odd shape and history set it apart from every other galaxy we know of.

The James Webb Space Telescope discovered an inexplicably dense galaxy inside an "Einstein ring" last year. Now, researchers think they can explain this cosmic conundrum.

New infrared observations from the James Webb Space Telescope unveil a galaxy far, far away that's creating new stars.

A new polarized light image of the supermassive black hole Sagittarius A* has given us our first clear look at the magnetic field of the cosmic juggernaut, which suggests that it may have superheated jets just like even larger black holes.

The ancient obect Gz9p3, which appeared as a single point of light through the Hubble Space Telescope, is actually one of the most enormous galaxies in the early universe, James Webb Space Telescope observations reveal.

Two supermassive black holes spotted circling inside a remote 'fossil' galaxy are the heaviest, and the closest, black hole binary ever found.

New observations with the James Webb Space Telescope reveal that dwarf galaxies in the early universe released enough collective radiation to change the cosmos forever.

The Hubble Space Telescope's latest image is a riot of orange, blue and violet — and a lesson in how plucky young stars clear their dusty neighborhoods.

For the first time, scientists discovered a powerful 'black hole wind' that blew through a nearby galaxy for hundreds of days, crushing star formation and reshaping the galaxy. Something similar may already have happened in the Milky Way.
