M53 and NGC5053 Two distant Globulars

M53: is an interesting Globular Cluster at a distance of 60,000 light years. This distance makes it one of the most distant of the outlying clusters.

Unlike the metal Rich M3, M53 is one of the most metal poor globular clusters. This would indicate that stars that comprise M53 were formed from gas that had not been recycled from stars of previous generations.

M53 is in Coma Berenices constellation and was discovered by Johann Bode in 1775.

NGC 5053: In the same frame and less than 1° from M53 is the less dense globular cluster NGC5053. While close to M53, NGC5053 wasn't discovered until 1784, 9 years later, when William Herschal cataloged it as VI-7.

NGC5053 and M53 are roughly the same distance from earth. Placing them within a couple of kpc's from each other. There is a tidal bridge joining them suggesting that they may have interacted sometime in the past.

At first glance NGC 5053 has the appearance of a dwarf galaxy. Like M53, 5053 is also a metal poor globular cluster. Given the low metallicity and motion of its stars, NGC 5053 may have been stripped from a dwarf galaxy, supporting its appearance as one. It may also have been robbed of stars during an interaction with more massive M53..

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.
