Open Cluster M52 (NGC7654) and Bubble Nebula (NGC7635)

Located in the constellation Cassiopeia and at a distance of approximately 5000LY, M52 is an open cluster of some 190 stars. At an angular separation of c35 arc seconds but at a considerably greater physical distance of approximately 11000 LY from M52 lies is an emission nebula NGC7635, commonly called the Bubble Nebula. The "bubble" is created by the stellar wind from a massive hot, young central star, SAO 20575 (BD+60°2522). The nebula is located within a giant molecular cloud which contains the expansion of the bubble while itself being excited by the hot central star, causing it to glow. The star BD+60°2522 is thought to have a mass of about 44 solar masses.

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.
