The M13 Hercules Globular Cluster

The M13 Hercules Globular Cluster, a stunning celestial object that has been captured in a 4.75-hour fast-track remote photography session. Located approximately 22,000 light-years away from Earth, M13 is said to contain around 300,000 stars. With the aid of a half-meter telescope's resolving power, numerous densely packed stars can be distinguished within this cluster. As one of the most prominent and well-studied globular clusters, M13 has been the subject of numerous scientific investigations. It also holds a special place in the history of human communication with the cosmos, as it was the target of the famous Arecibo message, a radio signal broadcast by the Arecibo Observatory in 1974 in an attempt to communicate with potential extraterrestrial civilizations.

In addition to the impressive star count within M13, the background of the image reveals some faint galaxies, each located at a distance of over a billion light-years away. These distant galaxies serve as a reminder of the vastness and grandeur of our universe, further accentuating the beauty of the M13 Hercules Globular Cluster.

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.
