M81 and M82

This image contains M81 and M82 which are repeat objects for me and the first deep space objects I imaged with my new 5 inch refractor. Messier 81 (aka Bode’s Galaxy) and Messier 82 (Cigar Galaxy) are two galaxies of the M81 Group, both about 12 million lightyears from Earth. The center of Bode’s Galaxy contains a 70 million solar mass super massive black hole. In February 2022, astronomers reported that Bode’s Galaxy may be the source of fast repeating radio bursts observed in May 2021. The Cigar Galaxy is a starburst galaxy more luminous than our Milky Way Galaxy with the center being 100 times more luminous than the center of the Milky Way Galaxy. The starburst is thought to be caused by gravitational interactions with Bode’s Galaxy.

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.
