NGC 4147

This object is a globular cluster located 60,000 light years away in the constellation of Coma Berenices. This is a dim cluster - there are over 100 other Milky Way globular clusters more luminous than this one. The stars appear fairly resolved to me across most of the cluster.

This cluster, located far above the Milky Way galactic plane, is relatively isolated from other globular clusters in the galaxy. Its distance from the Milky Way core suggests that it could have been a former member of one of the nearby Sagittarious dwarf galaxies.

Researchers have found that the inner section of this cluster is bluer than the outer section, perhaps because of a lack of red giants in the core area. The image shows this effect. Scientists also say that detailed images show that this cluster has S-shaped tidal arms, but I do not see that clearly in this image. A faint galaxy (PGC 38748) is visible in the lower left of the image.

The refractors!

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.
