Jellyfish Nebula - IC 443

The remnant of a cosmic explosion

-------------------------

The Jellyfish Nebula is a Type II supernova remnant: when a massive star (8-12x the mass of our Sun in this case) reaches the end of its life, its core collapses and then explodes ('supernova') producing a shockwave which pushes out most of the star's material.

This peculiar structure was created by such an explosion ~5,000 light years away, between 3,000-30,000 years ago and has a diameter of ~70 light years across.

The ejected material from the supernova interacts with the surrounding molecular cloud and is ionized by radiation from nearby stars.

The bright star on the top left is Propus, which is much closer to us than the nebula.

A very difficult target to image from a light-polluted area + it was very low in the West right after dusk during the imaging period, in March-April, but I am happy with the result.

This was also the very first result with my new mount: the Sky-Watcher AZ-EQ6 GT Pro!

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.
