NGC 488 is known as a prototype of a multi-armed spiral galaxy with a nearly perfect spiral structure, seen 46° from face-on. It’s angular size measures 5.5′ x 4.0′ and light needs about 95 million years to travel from this island in universe to us. William Herschel discoverd this galaxy in 1784 in the constellation of Pisces. Despite its small apparent size, the true diameter measures about 150’000 light-years.
