Hubble Views Bizarre Cosmic Quartet HCG 16 (IMAGE) ESA/Hubble Information Centre Caption This new NASA/ESA Hubble Space Telescope image shows four of the seven members of galaxy group HCG 16. This quartet is composed of (from left to right) NGC 839, NGC 838, NGC 835, and NGC 833 -- four of the seven galaxies that make up the entire group. They shine brightly with their glowing golden centers and wispy tails of gas, set against a background dotted with much more distant galaxies.
