M97 Owl Nebula

Revision title: increasing saturation

M97 as a planetary nebula about 2000 lightyears away from us in Ursa Major, spanning 1 lightyear in diameter and about 8000 years old.
A planetray nebula consists of the glowing ejected gases of a red giant star in their later life stage. A red giant is the last stage of a star before it collapses ino a white dwarf.

M97 consists of 3 outer shells that are being illuminated by its central star, which is 1/7th of our suns mass and turning into a white dwarf.
The particle and radiation pressure of the central star push out the gas shells into the interstellar medium.

The eye like structure for what ist called Owl Nebula is an affect of its innermost structure not being spherical like the 2 outer shells, but rather forming a barrel like structure that pierces through the outer shells.

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.
