"Surprising Trio of Galaxies Unveiled by Hubble Space Telescope (Photo)"

The Hubble Space Telescope has captured an image of two merging galaxies, NGC 7733 and NGC 7734, collectively known as Arp-Madore 2339-661. Within NGC 7733, a smaller galaxy called NGC 7733N has been discovered, previously obscured by dark dust. The three galaxies are interacting gravitationally and are on course to merge into a single, larger galaxy. The image shows the exchange of material between the galaxies as the larger one siphons gas and dust from its smaller companion.
