M37

M37 is an open cluster located 4700 light years away in the constellation of Auriga at a declination of 32 degrees. It is a magnitude 5.6 cluster which spans 19 arc-minutes in our apparent view. This corresponds to a diameter of 26 light years.

This open star cluster contains more than 500 stars. M37 is the most spectacular of the three open clusters in Auriga, with a contrast of sights including a brilliant orange star in the center, many young blue stars, and a high number of red giants.

M37 is called the Salt and Pepper Cluster. I don't find that to be a particularly appropriate or appealing nickname, although I know that almost all nicknames originated from their look in the eyepiece and not in an image such as this one.

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.
