M52/C11 The Bubble and the Cluster

M52/C11

NGC 7635 also known as the Bubble Nebula is a HII Region emission nebula located in northwestern Cassiopeia close to the border with Cepheus.
It appears round in shape due to expanding gas from the stellar wind of a massive hot central star (mag.+8.7). The nebula is located in a giant
molecular cloud that glows due to excitation from the star. It was discovered by William Herschel on November 3, 1787. It is 9,000 light-years away,
it's radius is 10 X 20 light-years.
.M52 is a mag. +7.2 open cluster located in western Cassiopeia. This excellent grouping of stars is one of the best clusters in the northern Milky Way,
with some 200 members spread across 13 arc minutes of apparent sky. It can be seen in binoculars and is a wonderful sight through telescopes,
appearing rich and bright with dozens of mainly white stars visible. M52 was one of Charles Messier's original discoveries, which he cataloged on
September 7, 1774. He spotted it when a comet he was observing passed close by. The cluster is 7,000 light-years distant wit a radius of 13.5
Light Years, and is about 35 million years old.

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.
