We present you a great classic: NC 2359 Thor's helmet, imaged in January 2021.

NGC 2359, more commonly known as Thor's Helmet, is a cosmic cloud in the shape of a helmet with appendages in the shape of a wing. Heroic in size even for a Norse god, Thor's Helmet is about 30 light years in diameter, making it more than 10 times larger than our entire solar system.

It is about 3,670 parsecs (11.96 thousand light years) from Earth. It contains several hundred solar masses. In reality, it looks more like an interstellar bubble, blown by a fast wind coming from the bright massive star in its center. Known as the "Wolf-Rayet Star" WR7, the central star is an extremely hot blue giant that is believed to be more than 280,000 times brighter than our Sun and 16 times more massive, which is in a brief phase of evolution preceding the supernova.

NGC 2359 is located approximately 15,000 light years from the constellation Cana Major. The image presented here is a mixture of data from different filters, which captured the stars and the glow of the nebula's filamentary structures. This highlights a blue-green color caused by a high emission due to oxygen atoms in the radiating gas.

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.
Dismissals 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.
