M82 (Arp 337)

M82 is an irregular galaxy located about 12 million light years away in the constellation of Ursa Major. It has a fascinating, irregular, distorted disk due to the interaction of its larger neighbor, M81. It is half the size of M81.

Our view of this galaxy is almost edge-on, at an inclination angle of 77 degrees. It is also known as Arp 337. The structure of this galaxy is so unusual that Dr. Halton Arp couldn't classify it, and it fell into the last category of the catalog called "Miscellaneous". It is called a starburst galaxy because it is undergoing a burst of new star formation. Through powerful winds from massive emerging stars, this burst of star formation in M82 is driving a huge outflow of reddish hydrogen gas from its galaxy core unlike that of any other galaxy. I like the dark lanes of dust running in strange patterns around the core of this unique 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.
