NGC 7635 a.k.a. Bubble Nebula
……………………………................
Space is full of things / situations / events that intrigue us, NGC7635 being one of those. In short and for everyone to understand, a massive star is caught in a "bubble". This star is almost 50 times larger than the Sun and the emitted radiation is about 1 million times stronger than it, producing a stellar wind that exceeds 5 million km per hour, wind that pushes dust and gas outward creating thus a shell or a bubble, a situation that obviously led to the popular name of this nebula.
As general information, the Bubble Nebula is an emission nebula with a diameter of about 7 light-years, located in the constellation Cassiopeia, at a distance of over 7000 light-years from Earth and it was discovered in 1787 by the British astronomer, William Herschel.
Specialists believe that in a short time ( meaning in the next 10-20 million years), the "guilty" star will consume its energy resources, and will explode, forming a supernova.

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.
