M13 - Great Hercules Cluster

A very powerful light is the one that illuminates deep space objects called star clusters. M13, also known as the Great Hercules Cluster, is one of them. It has several hundred thousand stars held together by gravity with a force of attraction much greater at the center than at the edges. The origin of star clusters is still uncertain, some of these objects are the oldest in the universe used precisely to estimate the age of the universe itself, others were formed by the formation of a star, after a nebula, which however have continued in their formation process at different times or with different composition. This cluster, M13, is about 25,000 light years away from us and is one of the largest observable from the Northern Hemisphere. The count of stars inside varies from 300,000 to 500,000 and the largest stars are red-orange giants, they can be clearly distinguished from the photo. The peculiarity of this cluster is that in 1974 a message was sent from the Earth which contains information relating to the human race, DNA, atomic numbers of fundamental elements for life and the position of the Earth in the Milky Way. This experiment served to send a message to potential extraterrestrial civilizations, and this deep space object was selected because it is large and was "close enough" when it was decided to send a message. The message will arrive at the first group of stars in 25,000 years and it will take, at least, the same amount of time for any response.

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.
