Close-up to M81-M82 with IFN

Les galaxies M81 et M82 se trouvent dans la constellation de la Grande Ourse.Le groupe M81-M82 fait parti du superamas de la Vierge.Les galaxies M81 et M82 se situent à environ 12 millions d’années-lumière.Leur proximité n’est cependant pas synonyme de conformité, puisque ces trois galaxies présentent des morphologies très différentes !M81 est une galaxie spirale dont le diamètre est estimé à environ 87 000 années-lumière.Il existe un effet de marée gravitationnelles avec M82 lié a la proximité de cette dernière.

M82 est classée parmi les galaxies « à sursaut d’étoiles ». Cela signifie que le taux de création d’étoiles y est beaucoup plus élevé que le taux moyen observé dans les autres galaxies.

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.
