Arp 273 is a group of galaxies which interact with each other. The constellation is 300 million light years away from Earth in the constellation Andromeda. The Andromeda galaxy is also located in the Andromeda constellation. The larger of th...
Most of the galaxies visible in this Hubble image are members of a huge cluster called CLASS B1608+656, which lies about five billion light-years away. But the field also contains other objects that are both significantly closer and far more distant — including two gravitational lenses dubbed Fred and Ginger.
These contain enough mass to visibly distort the light from objects behind them. Fred, also known more prosaically as [FMK2006] ACS J160919+6532, lies near the lens galaxies in CLASS B1608+656, while Ginger ([FMK2006] ACS J160910+6532) is markedly closer to us. Despite their different distances from us, both can be seen near to CLASS B1608+656 in the central region of this Hubble image, and are labelled.
