Constellation: Ursa MajorM81, commonly known as Bode's Galaxy, is a grand design spiral galaxy located in the constellation Ursa Major. Close by is M82, the Cigar Galaxy. The gravitational interaction between these galaxies have led to the distinctive shapes. For example, M82's starburst activity and its interesting outflows of ionized hydrogen result from its interaction with M81.This event results in an extremely high rate of star formation, and M82 shines brightly in infrared wavelengths. NGC 3077 is another galaxy in the vicinity and is also thought to be interacting with the other two, although it's less dramatic in appearance.Details accurate to the best of my knowledge from research done in 2022.

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.
