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 ...

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 ...

The Euclid space telescope has spotted 26 million galaxies in just one week of observations. The European Space Agency (ESA) ...

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

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 ...

"Starburst galaxies birth lots of hot blue stars that burn fast and die quickly in explosions that unleash intense ...

In these fields they identify more than 140000 extragalactic systems, including various astrophysical exotica: interacting galaxies, various types of active galactic nuclei, radio galaxies, and ...

and typically result from disruption by the gravitational pull of neighboring galaxies. Such interactions between nearby galaxies, which may ultimately result in galaxies merging, may induce ...

One possible theory regarding the formation of UDGs suggests they form when filaments of gas are dragged from larger galaxies via gravitational interactions. If gas clouds remain in these ...
