M82 - CIGAR GALAXY

The Cigar Galaxy (also known as M82) is a visible galaxy in the constellation Ursa Major. At magnitude +9.3 and approximately 11.5 million light-years distant from Earth, it is a typical starburst galaxy.
In starburst galaxies, the star formation process is exceptionally violent compared to the normal rate of formation in most galaxies. Such galaxies show a peak in the formation of new stars, especially after a collision or close encounter with other galaxies. In the case of M82, the nearby M81 is believed to have triggered this process. M81 also gravitationally influences M82 via tidal forces that deform the shape of the galaxy and increase star formation activity.
The Cigar Galaxy is part of a group of galaxies known as the M81 Group or NGC 3031 Group, one of the groups closest to the Local group (where it is located in the Milky Way).
The image was obtained in collaboration. Claudio Fiore collected the ionized hydrogen signal typical of the starburst phenomenon from his 10" schmidt newton; Michele Russo integrated the RGB channel with me. I borrowed the beautiful 8" Omegon Ritchey-Chrétien of Salvo Semilia.

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.
