☞ When Galaxies collide…

August 11, 2011

A composite image created by combining data from the Chandra X-Ray Observatory and the Hubble Space telescope, this is a stunning image of two galaxies colliding. Both of them are spiral galaxies, and they are on the verge of a collision—with their disks oriented at 90 degrees to each other!

Well, “on the verge” is in galactic time scales, which means they’ll collide in a few million years. And considering that this is 450 million lightyears away from us, the event has already occurred—we just haven’t seen it yet.

A detailed description of the image is present as a caption with the photo itself. Go see it!
