M67

This Messier open cluster is located 2900 light years away in the constellation of Cancer at a declination of +12 degrees. It spans about 25 arc-minutes in our apparent view. This corresponds to a diameter of 20 light years.

This is the oldest open cluster in the Messier catalog. Typically, open clusters are younger and their stars tend to disperse over time, usually before they reach this age. This cluster still has about 100 larger stars similar to our Sun, and over 500 stars in total. Note the contrast between the hotter (bluish) and cooler (reddish) stars of the cluster. The cluster is roughly the same apparent size as the full Moon and is located fairly close to earth.

This cluster is nicknamed the King Cobra Cluster. I don't really see that in this cluster. There is a pair of bluish bright stars at 5 o'clock, so perhaps that is the Cobra head, but I don't have enough imagination to see a snake here.

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.
