At about 62 million light years distant, the Fornax Cluster of galaxies, also known as Abell S0373, is the second closest galaxy cluster to our Milky Way. (The immense Virgo Cluster is about 48-54 million light years away). The yellowish galaxies are ellipticals. NGC 1365 is a beautiful barred spiral.
Compact galaxy group, Stephan's Quintet, in Pegasus. Four of these galaxies are interacting and will eventually merge into a mega galaxy. NGC 7319, 7318A, 7318B, and 7317 have a yellowish cast. Blue spiral NGC 7320, however, is 260 million light years away from the other four, which are 300 light-years from Earth. (NGC 7320 is only 40 million light-years away from Earth.) To the upper left is another galaxy, NGC 7320C, is also about 300 million light-years away.
NGC 5194. Over 60,000 light-years across, M51's spiral arms and dust lanes clearly sweep in front of its companion galaxy (top), NGC 5195. Image data has been reprocessed to produce this alternative portrait of the well-known interacting galaxy pair. The processing has further sharpened details and enhanced color and contrast in otherwise faint areas, bringing out dust lanes and extended streams that cross the small companion, along with features in the surroundings and core of M51 itself.
NGC 4038 and NGC 4039 are galaxies in collision, some 60 million light-years from Earth in the constellation Corvus. Collectively, they are known as The Antennae because of the long tidal tails resultant from the gravitational interactions of the two galaxies.
