M 94 – Spiral galaxy


The spiral galaxy Messier 94 is located in the constellation Canes Venatici (Hunting Dogs) about 14 million light years from us. Among its peculiarities, we note a star formation disc around the nucleus. Also seen there (visible in my photo) is an outer star ring which actually turns out to be a complex structure of spiral arms in which there is also intense star forming activity.

At the center of this galaxy, there is a supermassive black hole with a mass between 3 and 14 million times the mass of our Sun.
