M81, M82 and the IFN

The M81 Galaxy, also called the Bode Galaxy, in honor of the scientist who discovered it, Johann Elert Bode in 1774, and the M82 Galaxy, known as the Cigar Galaxy, are located to the North in the constellation of the Big Dipper, about 12 million years ago. Light.
It is an area rich in Integrated Flow Nebulae, known as IFN for its acronym in English.
It was Esteve Mandel-Wilson who coined the term IFN and defined them as "high galactic latitude nebulae that are illuminated not by a single star (like most nebulae in the plane of the Galaxy) but by the energy of the integrated flux." of all the stars in the Milky Way.
These nebula clouds, a major component of the interstellar medium, are composed of dust particles, hydrogen and carbon monoxide, and other elements.

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.
