NGC 2359 - Thor's Helmet

Link: http://www.jthommes.com/Astro/thorhelmet.htm

NGC 2359 is also known as "Thor's Helmet" due to its distinctive shape. The "helmet" shape is a gas bubble formed by a very energetic Wolf-Rayet star (HD56925) in the center of this bubble. The bubble is formed from the expelled outer layers of this star that are ejected at high velocity. NGC 2359 is also cataloged as Sh2-298, GUM 4 and LBN 1041. Thor's Helmet is about 16,000 light years distant. Also in this image is NGC 2361 (a knot - as part of NGC2359), and the weak emission region IC 468 (also cataloged as LBN 1040). These objects and some of the brighter stars are identified in the annotated image.

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.
