Arp 147
Just in time for Valentine's Day comes a new image of a ring -- not of jewels -- but of black holes. This composite image of Arp 147, a pair of interacting galaxies located about 430 million light years from Earth, shows X-rays from the NASA's Chandra X-ray Observatory (pink) and optical data from the Hubble Space Telescope (red, green, blue) produced by the Space Telescope Science Institute (STScI) in Baltimore, Md.

Arp 147 contains the remnant of a spiral galaxy (right) that collided with the elliptical galaxy on the left. This collision has produced an expanding wave of star formation that shows up as a blue ring containing in abundance of massive young stars. These stars race through their evolution in a few million years or less and explode as supernovas, leaving behind neutron stars and black holes.

A fraction of the neutron stars and black holes will have companion stars, and may become bright X-ray sources as they pull in matter from their companions. The nine X-ray sources scattered around the ring in Arp 147 are so bright that they must be black holes, with masses that are likely ten to twenty times that of the Sun.

Only the idea of colliding

Only the idea of colliding galaxies should be enough to amaze someone, but this picture show it for real
and is fantastic.
A ring, not a silver jewelry of course, but still very nice, of young stars and black holes traveling through space right in front of us, that's speechless!

2much to imagine this

Hi, while reading what this picture is about, i'm just totally astonished. its hard to imagine that this stuff is real, but it is. A ring of black holes ... its just incredible - btw: it's also hard to imagine that some people aren't fascinated in developing things like this. Anyway the Arp 147 Picture is beautiful - wether you re interested in things like this or not :)

would be nice to have a possibility to watch those things with google universe or something like this.
