The Jellyfish Nebula and Friends

The Jellyfish Nebula, IC 443, is a supernova remnant in the constellation Gemini and lies some 5000 light years away. Covering an angular diameter of almost 2x the full moon, the remnant is roughly 70 light years across at that distance. The parent star is thought to have gone supernova 3000 - 30000 years ago. This has historically been a very active region in the sky as another partial SNR shell can be found to the left of the Jellyfish. This is associated with an even older supernova remnant G189.6+3.3 and is dated to around 100000 years old.

To the left lie LDN 1568 a dark nebula, LBN 189.33+04.40, a reflection nebula and LBN 188.69+04.25, an HII region. I think it's cool that from our vantage in the vicinity of two stellar deaths, we see a region of active star formation.

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.
