M82 (aussi connu comme NGC 3034 et sous le nom de galaxie du Cigare) est une galaxie spirale située dans la constellation de la Grande Ourse à environ 12,7 millions d'années-lumière de la Voie lactée.

M82 est environ 5 fois plus lumineuse que la Voie lactée et son centre est des centaines de fois plus lumineux que celui de notre galaxie12. On pense que l'intense formation d'étoiles provient de l'interaction gravitationnelle avec sa voisine M81. Comme c'est la galaxie à sursaut de formation d'étoiles la plus rapprochée12 de la Terre, elle constitue une cible favorite pour l'étude de ce genre de galaxie.

En 2005, on a découvert à l'aide du télescope spatial Hubble 197 jeunes amas d'étoiles massives près du cœur de M82. La masse moyenne de ces amas avoisine les 200 000 masses solaires. Le cœur de M82 constitue donc un environnement très dense de très haute énergie.

Au centre de M82, les étoiles se forment à un rythme 10 fois supérieur à celui de toute la Voie lactée.

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.
