Messier 81 (NGC 3031) in Ursa Major is one of the most conspicuous spiral galaxies in the sky. It forms a physical pair with its neighbor, M 82, and is the dominant galaxy of the M81 group.
M 81 is probably about 12 million years away, as determined by Hubble Space Telescope observations of Cepheid variables within it. The true diameter of M 81 is at least 70,000 light years; its mass has been calculated to be around 250 billion suns. This makes it somewhat heavier than our Milky Way. The absolute magnitude of M 81 is -20.8, a luminosity of 17 billion suns.M 81 is the brightest of a group of 34 galaxies called the Messier 81 Galaxy Group. The distance to the center of the cluster is about 12 million light years. It is the second nearest galaxy group to our Local Group (after the Sculptor Galaxy Group, about 8 million light years away). The M 81 Group includes, in addition to its two Messier members, NGCs 2976 and 3077 in Ursa Major, NGCs 2366 and 2403 in Camelopardalis, and NGC 4236 in *Sky Safari Pro 6

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
