Hot on the heels of that fabulous Spitzer image comes news that Hubble and Spitzer have teamed up to find what may be the most distant galaxy ever seen. It appears to be at a distance of 12.8 billion light years. Yikes. Here's the image (click to make it more cromulent):
The big image shows the incredible galaxy cluster Abell 1689, a well-studied city of galaxies. The combined gravity of the galaxies in that cluster act as a lens, distorting and magnifying the light of galaxies on the other side, more distant galaxies that might be too faint to be seen on their own. The arcs you see are all more distant galaxies, their light strewn out by the gravity if the intervening cluster (see how they all appear to have the center of the cluster as their own center of curvature?). Even boosted by this gravitational lens, the light ...
