M81 and M82

Messier 8`1 (Bode's Nebula) and Messier 82 (The Cigar Galaxy)

M81 and 82 are found in the constellation of Ursa Major. M81 is about 12 million light-years away. Which in astronomical terms is very close to Earth. Meaning that is is heavily studies and observed due to its large size, proximity and active galactic nucleus contains a 70 million solar mass black hole.

M82 is again about 12 million light-years away and is a starburst galaxy. It is about five times more luminous than the Milky Way and has a centre one hundred times more luminous. As a starburst galaxy it is extremely active, containing one of the brightest pulsars ever discovered.

Unfortunately due to a guiding camera failure I lost a LOT of Ha data which would have enhanced some of the fainter detail in M82. I may try to obtain this at a later date and add it in.

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.
