Astronomy Picture of the Day -- The M81 Galaxy Group Through the Integrated Flux Nebula
NASA ^ | March 13, 2012 | (see photo credit)

Explanation: Large galaxies and faint nebulae highlight this deep image of the M81 Group of galaxies. First and foremost in the wide-angle 12-hour exposure is the grand design spiral galaxy M81, the largest galaxy visible in the image. M81 is gravitationally interacting with M82 just below it, a big galaxy with an unusual halo of filamentary red-glowing gas. Around the image many other galaxies from the M81 Group of galaxies can be seen, as well as a lucky satellite glint streaking across the image left. Together with other galaxy congregates including our Local Group of galaxies and the Virgo Cluster of galaxies, the M81 Group is part of the expansive Virgo Supercluster of Galaxies. This whole galaxy menagerie is seen through the faint glow of an Integrated Flux Nebula, a little studied complex of diffuse gas and dust clouds in our Milky Way Galaxy.

What always surprises me is how big M81 really appears.

On an average night, the nucleus is about all you see.

On a great night, you can see the spiral structure and the arms just go on and on.

One of my favorite items.
