Galaxy Messier 88
History
The galaxy M 88 was discovered by Charles Messier on 18 March 1787. He wrote: «Nebula without a star, in Virgo, between two small stars and a star of the sixth magnitude, which appear simultaneously in the field of view of the telescope. The brightness is one of the weaker and is like no. 58 in Virgo.» [281]
Physical Properties
M 88 is a spiral galaxy with well-defined and symmetrical spiral arms. It is about 47 million light years away and one of the fifteen Messier galaxies in the Virgo Cluster. It is a Seyfert galaxy and has an active core, which means that the central area of the galaxy is brighter than the rest of the galaxy. In the centre there is a supermassive black hole with about 100 million solar masses. M 88 contains about 400 billion stars and is moving away from our galaxy. [215]
