IC 443 in HOO palette

IC 443, also called SNR G189.1+03.0, 3C 157, Sh2-248 and CTB 20.1 is a supernova remnant located in the constellation Gemini. It has a diameter of approximately 50 arcminutes and belongs to the Gem OB1 stellar association. It is also informally called the Medusa Nebula.

IC 443 is a supernova remnant of mixed morphology. In the visible spectrum and in radio frequencies, it shows a shell-like morphology, and consists of two interconnected subshells, each of them of a different size and with a different center. A third, larger subshell, initially attributed to IC 443, is now considered the remnant of another, older supernova (approximately 100,000 years old).

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.
