NGC 1277

NGC 1277 is a lenticular galaxy in the constellation of Perseus. It is a member of the Perseus Cluster of galaxies and is located approximately 220 million light years from the Milky Way. It has a visual magnitude of 14.7. It was discovered on December 4, 1875 by Lawrence Parsons, 4th Earl of Rosse.
==Ancient stars==
NGC 1277 has been called a "relic of the early universe" because its stars formed during a roughly 100 million year interval 12 billion years ago, when the universe was only about 2 billion years old. After this burst of star formation, a thousand times the rate of star formation in our own Milky Way galaxy, this generation process shut off, leaving NGC 1277 populated with metal-rich stars about 7 billion years older than our Sun.〔(【引用サイトリンク】title=Discovery of a "Relic" Galaxy, Frozen in Time )
