M81

 

M81

 

M81, a large type Sb spiral galaxy, is at the center of a small group of galaxies which, in intergalactic terms, is located in our neighborhood, about 7 million light years distant.

M81 is one of the brightest spiral galaxies to be seen in a telescope, and is easily visible in binoculars. It has a "grand-design" spiral pattern, meaning it has pronounced spiral arms which are clearly defined around the whole galaxy. It is a spiral galaxy not unlike our own. In 1993, a type II supernova (1993J) occurred in M81, which reached a brightness of about mag 10.5 in its maximum. M81 was originally discovered by Johann Bode, who found it, together with its neighbor M82, in 1774.
