Prof. Alex Filippenko of the University of California at Berkeley and Dr. Luis Ho of the Carnegie Observatories have announced that a Massive Black Hole has been found which could change the scientific idea of spiral gallaxies.
The Gallaxy known as NGC 4395 is a flat pure-disk galaxy about 11 million light-years away in the Northern Hemisphere constellation of Canes Venatici. The discovery suggests that other pure-disk galaxies, thought to be devoid of supermassive black holes, may indeed have one.
