M13 - The Hercules Cluster

Over 100,000 stars whirl within the globular cluster M13. Located 25,000 light-years from Earth in the constellation Hercules, it is one of the brightest star clusters visible from the Northern Hemisphere.

Globular clusters are tightly packed, symmetrical collections of stars, orbiting mostly in the extended star halos surrounding most spiral galaxies. They contain some of the oldest stars in a galaxy and are thought to have formed early in its history; that is why they tend to contain many red giants and few newer blue stars. These stars are so crowded that they can, at times, run into each other and even form a new star.

If you look closely, you may be able to see the famous "propeller," a Y-shaped feature made of three narrow, dark lanes at 120° angles to one another. It is barely visible at around the 5 o'clock position. You may also be able to pick out some of those young, blue stars.

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.
