Caption: Gas cloud surrounding interacting galaxies, Spitzer Space Telescope image. This mysterious object (centre, red), known as High Redshift Galaxy Cluster J2143-4423, has been a source of some confusion for astronomers. It is one of a number of objects termed 'giant galactic blobs'. The three galaxies inside (centre) are merging together and are surrounded by huge clouds of intensely glowing gas (red). Current hypotheses suggest that the energy from the merging galaxies is in some way transferring to make the gas glow, but the exact mechanism is still a mystery.
