galaxies

From nebulas and black holes to baby star nurseries and ancient collisions, the universe has never looked more beautiful thanks to NASA's $10 billion-telescope.

A new image from the James Webb Space Telescope shows Arp 107, home to two merging galaxies, with two bright cores and a "bridge" of dust and gas forming a cosmic smiley face.

The Andromeda Galaxy, the Milky Way's closest galactic neighbor, glows brightly in a new Hubble Space Telescope image with swathes of ionized gas that fuel star formation.

Astronomers using the James Webb Space Telescope have discovered a pair of distant galaxies being twisted into a cosmic question mark thanks to a rare form of gravitational lensing.

These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.

The Triangulum Galaxy, the third-largest member of the Local Group of galaxies, is shining with star formation in a new image from the Hubble Space Telescope.

'The bottom line is, there is no crisis in terms of the standard model of cosmology.

NGC 6744 is a spiral galaxy bigger than, but otherwise very similar to, our own. NASA has dubbed the large spiral galaxy the Milky Way’s ‘big brother’.

The new AI system can estimate cosmological parameters with stunning precision, and it could help astronomers unpick one of the thorniest problems in the field.

Astronomers have long predicted that a collision between our galaxy and nearby Andromeda could be inevitable, but new calculations suggest this may be an over exaggeration.
