NGC 7635 - Bubble Nebula

NGC 7635, also known as the Bubble Nebula, is a stunning emission nebula located in the constellation Cassiopeia, approximately 7,100 light-years away from Earth. This celestial wonder is named after its distinctive bubble-like appearance, created by the intense radiation and stellar winds from a massive, hot, and young star at its center, known as BD+60°2522.The Bubble Nebula spans about 10 light-years in diameter and is an active region of star formation. The star's powerful radiation ionizes the surrounding hydrogen gas, causing it to emit a reddish glow characteristic of emission nebulae. The bubble structure results from the interaction between the expanding stellar wind and the surrounding molecular cloud.NGC 7635 is a favorite target for amateur astronomers and astrophotographers, as it presents a visually striking and photogenic sight through telescopes and long-exposure photography. Observing this celestial spectacle allows us to marvel at the forces of nature and the intricate beauty of our universe.

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.
