"Helix Nebula" - SHO

Link: https://millenniumphoton.com/portfolios/ngc7293-helix/

La nébuleuse planétaire "Helix" dans la constellation du Verseau, l'une des plus proches de la Terre à 700 années-lumière environ. La structure annulaire s'étend sur plus de 2,5 années-lumière.

Cette nébuleuse résulte de l'expulsion de ses couches extérieures par l'étoile centrale en fin de vie.

On peut voir dans la partie centrale de la nébuleuse des "noeuds cométaires", dont la partie centrale est d'une taille comparable au système solaire. On estime leur nombre à plus de 20 000 dans cette nébuleuse, où ce type de structures a été découvert.

The Helix planetary nebula in Aquarius is one of the closest of the Earth, with an estimated distance of about 700 LY.

This nebula is formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution.

The Helix Nebula was the first planetary nebula discovered to contain cometary knots, which, excluding the tails, are approximately the size of the Solar system. More than 20,000 cometary knots have been estimated in this nebula.

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.
