Wild's Triplet
Wild's Triplet, also known as Arp 248, is a small group of three spiral galaxies that gravitationally interact with each other. The galaxies (PGC 36723, PGC 36733, and PGC 36742) lie in the Virgo constellation about 200 million light-years away. Two of the galaxies have a connecting stream of stars likely formed by their gravitational pull on each other. The triplet is named after Swiss astronomer Paul Wild, who studied the group in the early 1950s. A picture from the Hubble Space Telescope shows part of the system.
