NGC2359_Thor's Helmet HaOIII

NGC 2359, also known under the name of Helmet of Thor, is a nebula in emission, situated in the Canis Major constellation. Gigantic, it covers an angle equivalent to 3 full moons. The central, at the same time massive and very hot star, is a giant who runs her last red lights of helium and carbon. It produces by this effect a powerful interstellar wind, a bubble of gas in which escapes a part of its material. Titanic, violent), the helmet of Thor is the sîgne of a cataclysm to come. An explosion of the star in supernova, which could give birth to a black hole...

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.
