Messier 13 - Hercules Globular Cluster

Messier 13, called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of several hundred thousand stars in the constellation of Hercules.

About 145 light-years in diameter, M13 is composed of several hundred thousand stars and it is 22,200–25,000 light-years away from Earth. It is estimated to be over 11 billion years old.

Compared to the stars in the neighborhood of the Sun, the stars of the M13 population are more than a hundred times denser. They are so densely packed together that they sometimes collide and produce new stars. The newly formed, young stars, are sometimes called "blue stragglers".

The 1974 Arecibo message, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope towards M13 as an experiment in contacting potential extraterrestrial civilizations in the cluster.

I've taken the data from my balcony, while waiting for the main target to rise above a certain altitude. This time of year is when my balcony chooses the target, without any say from my side. M92 was its choice last year and here is M13. Yes, I live by the grace of my balcony's wisdom.

Clear skies!

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.
