Thor's Helmet Nebula is an emission nebula located in the consteallation Canis Major, the Great Dog. For those of us in the northern hemisphere this places Thor very low in our southern sky during the winter months. This visually striking nebula, with its bubble shape and wing-like filaments, looks a lot like the helmet worn by the norse god of thunder, Thor. It's appealing, big, and it's bright making it a popular target for astrophotographers.

NGC 2359 spans 30 light-years and is approximately 12,000 light-years from earth. At its core is WR7, over 280,000 times brighter than our sun. WR7 is an extremely hot star thought to be in a brief pre-supernova stage of evolution. Thor is largely interstellar material swept up by winds from the central star, although some material does appear to be enriched with the products of fusion and is likely to come directly from the star.

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.
