M-92: The Great Globular Cluster in Hercules (Fernando)

M-92: The Great Globular Cluster in Hercules

This cluster with age between 12 and 14 billion years, is one of the oldest known. It is very metal-poor, having a mass of 400.000 Suns.

It's size is 12.2 arc -sec what corresponds to a diameter of about 100 light years. It orbits the galaxy in an orbit with around 20 deg of inclination respect to the disk what takes the cluster to 13 million years away from the galactic center.

Recent simulations have shown that M-92 complete completes one revolution around the galaxy once every hundred million years.

The distance from Solar System is 27 thousand Ligh Years.

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.
