A gauche, M81 (NGC 3031) est une galaxie spirale située dans la constellation de la Grande Ourse à environ 12,0 millions d’années-lumière de la Voie Lactée. Son diamètre est relativement modeste puisqu’il ne fait que 87000 années-lumière.

A droite, M82 (aussi connu sous le nom de NGC 3034 et également appelé galaxie du Cigare) est une galaxie spirale située à environ 12,7 millions d’années-lumière. C’est une Galaxie dites à sursaut d’étoiles, en effet elle présente un taux exceptionnel de formation d’étoiles, du à l’interaction gravitationnelle avec M 81.Le taux de formation des étoiles est dix fois plus important que dans une Galaxie isolée.

Nous apercevons sur cette photo les jets d’Hydrogène ionisée, perpendiculaire au disque de la galaxie.

Dans le coin supérieur gauche nous apercevons Ngc 3077 qui se trouve à la même distance. Elle subit également les effets gravitationnels des deux autres galaxies.

Également visible sur la Photo: L’IFN (Integrated Flux Nebulea), est un gaz de poussière en avant-plan qui appartient à notre Galaxie.

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.
