Astronomers have discovered an extremely rare group of five 'dwarf' galaxies that are 'interacting with each other' about 117 million light years away from Earth Dwarf galaxies contain a few ...

Young stars enveloped in a transformative cocoon of gas shine brightly in a new image from the Hubble Space Telescope.

These two galaxies are so tight, the stellar formation encompassing them both actually has a name of its own. Say hello to Arp 91, a pair of spiral galaxies that are situated so close together (in ...

Many galaxies are visible in this deep field exposure, and its just a part of a larger mosaic, zoomed in 16 times.

Take this newly shared image of UGC 2369, a designation that actually applies to two different galaxies that are slowly, inexorably merging into one. This phenomenon of interacting galaxies comes ...

Webb’s view shows that their interaction is marked by a glow of scattered stars represented in blue. Known jointly as Arp 142, the galaxies made their first pass by one another between 25 and 75 ...

Pair of Interacting Galaxies: The two interacting galaxies making up the pair known as Arp-Madore 608-333 seem to float side by side in this image from the NASA/ESA Hubble Space Telescope.

NASA's newest space telescope rocketed into orbit Tuesday to map the entire sky like never before—a sweeping look at hundreds of millions of galaxies and their shared cosmic glow since the ...

A recent image from the Hubble Space Telescope captures a gorgeous spiral galaxy bursting with new star formation.

Fossil groups and LRGs represent a late stage of evolution in galaxies where activity has slowed. Few stars form in LRGs so they're "red and dead." There's also little to no interaction between ...
