NGC4527, Joe Girolamo

NGC4527

NGC4527 is a spiral galaxy that is about twenty times the distance from earth as our closest neighbor galaxy, the Andromeda Galaxy, and is located within the Virgo Cluster of galaxies. NGC4527 is categorized as a "starburst" galaxy because of its abundant molecular gas and high star formation rate. In 1991 a supernova occurred in this galaxy.

The outer reaches of NGC4527 (as seen in the image) appear cloudy because of the abundance of gases within the galaxy. The angular size is 1.31 arc minutes and the linear size of the galaxy is about 16 thousand light years given that the distance is 44 million light years. This number is approximate because the galaxy's distance is hard to determine.
