A curious pair of galaxies
The ESO Very Large Telescope has taken the best image ever of a strange and chaotic duo of interwoven galaxies. The images also contain some surprises -- interlopers both far and near.

(Phys.org)—Almost thirty years ago the Infrared Astronomy Satellite, IRAS, discovered that the universe contained many fabulously luminous galaxies, some of them more than a thousand times brighter...
View ArticleHubble sees cosmic "flying V" of merging galaxies
This large "flying V" is actually two distinct objects—a pair of interacting galaxies known as IC 2184. Both the galaxies are seen almost edge-on in the large, faint northern constellation of...
View ArticleGalaxy collisions
Collisions between galaxies are common. Indeed, most galaxies have probably been involved in one or more encounters during their lifetimes. One example is our own Milky Way, which is bound by gravity...
View ArticleHubble tells a tale of galactic collisions
(Phys.org) —When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of...
View ArticleHubble spots a very bright contortionist
(Phys.org) —The contorted object captured by Hubble in this picture is IRAS 22491-1808, also known as the South America Galaxy. It is an ultra-luminous infrared galaxy (ULIRG) that emits a huge amount...
View ArticleHubble spots galaxies in close encounter
(Phys.org) —The NASA/ESA Hubble Space Telescope has produced this vivid image of a pair of interacting galaxies known as Arp 142. When two galaxies stray too close to each other they begin to interact,...

View ArticleHubble eyes galaxy as it gets a cosmic hair ruffling
(Phys.org) —From objects as small as Newton's apple to those as large as a galaxy, no physical body is free from the stern bonds of gravity, as evidenced in this stunning picture captured by the Wide...
View ArticleWhere do stars form in merging galaxies?
Collisions between galaxies, and even less dramatic gravitational encounters between them, are recognized as triggering star formation. Observations of luminous galaxies, powered by starbursts, are...
