The Shining Bubble - NGC 7635

NGC 7635, also known as the Bubble Nebula or Sharpless 162 was discovered in 1787 by William Herschel. At distance of ~7100 ly in constellation Cassiopeia, the bubble is 7 light years in diameter and is formed by very hot and massive O-star - the one at 6 o'clock near the border. The hot stellar winds forming the nebula are facing bigger resistance cold interstellar clouds in the lower part of the image than in the other directions, so the nebula expands uneven. This is the reason the star to be off the bubble center. The nearby cool hydrogen gas is shaped in pillars similar to the famous "Pillars Of Creation" and their presence is a sing of possible star formation activities.

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.
