NGC 7293_ HELIX NEBULA

The Helix Nebula (also known as NGC 7293, C 63 or the Helix Nebula keeping its English name) is one of the planetary nebulae closest to Earth. It is located 650 light years from Earth The Helix Nebula is an example of a planetary nebula formed at the end of the life of a solar-type star. The outer gaseous layers of the star ejected into space represent from our point of view as if we were looking down on a helix. The central core of the star, destined to become a white dwarf, shines so intensely that it makes the previously expelled gas fluoresce. This magnificent nebula was taken by my amateur astronomer friend Roberto Volpini and he gave me the opportunity to process it. It is a subject that I have never taken up again until now but I have always wanted to try to elaborate. Thanks again Roberto.

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.
