Title
Merging Galaxies, Cosmic Collisions
Full Description
Exciting Hubble Space Telescope images of more than a dozen very
distant colliding galaxies indicate that, at least in some cases, big
massive galaxies form through collisions between smaller ones, in a
generation after generation never-ending story.
The Hubble image shows the paired galaxies very close together with
streams of stars being pulled out of the galaxies. The colliding
"parent" galaxies lose their shape and smoother galaxies are formed.
The whole merging process can take less than a billion years.
The Hubble Space Telescope imaged 81 galaxies in the galaxy cluster 8
billion light-years away. Astronomers say the collisions have never
been observed before at this frequency. Many of the collisions involve
very massive galaxies, and the end result will be even more massive
galaxies.
