Messier 94

Messier 94 (also known as NGC 4736 ) is a spiral galaxy with dimensions of 11.2 ' x 9.1 ' and the apparent magnitude of 8.1 mag in the constellation hunting dogs.

She is one of the brightest galaxies in the Canes Venatici - I group, a group of galaxies in the nearby vicinity of the Local Group within the Virgo supercluster.

Discovery

The galaxy Messier 94 was discovered on 22 March 1781 by the French astronomer Pierre Méchain.

Properties

It is a LINER galaxy, a form of AGN galaxies whose core region containing weakly ionized gas.

The galaxy contains two rings, of which the inner is characterized by a very high rate of star formation, which in turn is caused by the ejection of gas from the center. M94 is therefore classified as a starburst galaxy.
