M13 _ Hercules globular cluster

M13 L= synthetique RGB

L'amas globulaire M13 ou Messier 13, très souvent appelé le Grand Amas d'Hercule ou simplement Hercule, est parmi les objets les plus imposants du catalogue Messier. Il a été découvert par Edmond Halley en 1714, et ajouté par Charles Messier dans son catalogue le 1er juin 1764.

Comportant plus de 500 000 étoiles, il est aussi l'un des plus vieux objets : son âge est estimé à 12 ou 14 milliards d'années. Il apparaît avec un diamètre de 20 minutes d'arc, soit un diamètre réel de 150 années-lumière. Il a cependant la particularité de contenir de nombreuses étoiles jeunes (appartenance confirmée d'après leur vitesse angulaire), ce qui est inhabituel pour un amas de cet âge : les scientifiques pensent que ces étoiles ne sont pas nées à l'intérieur de l'amas, mais ont plutôt été capturées par ce dernier.

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.
