M53

M53 is an interesting globular cluster in the constellation of Berenice's Hair (Coma Berenices).

Globular clusters are very dense, roughly spherical groups of hundreds of thousands of stars that are tied together by a strong gravitational force - the closer to the center, the higher the density of stars. These clusters typically contain old stars that have been around for roughly the age of our Galaxy itself - over 10 billion years. Our Galaxy has about 150 of such clusters spread around its outer edge.

M53 is located about 58,000 light years away from Earth. It measures across about 220 light years and contains about half a million of stars, most of which are about 12.5 billion years old.

The M53 cluster is different from most other globular clusters, because its stars contain very low percentage of elements heavier than helium in their outer layers. This indicates that they are the first generation of stars since the Big Bang, as opposed to the majority of our Galaxy's globular clusters, where stars have been formed from the "recycled" gas and dust from previous generation of stars (and therefore containing other elements which were forged by nuclear fusion in their centers).

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.
