Jellyfish Nebula

IC 443 – The Jellyfish Nebula is a Galactic Supernova Remnant (SNR), 5,000 light years away from us in the constellation of Gemini, spanning 70 light years across. Around 30,000 years ago, this cosmic structure began to form when a huge star collapsed in a sizzling supernova, creating not only an expanding shockwave of molecular nebulosity, but also an infinitesimally sized, but massive neutron star. The bright yellow star in the bottom, Eta Geminorum or Propus, is actually a triple star system roughly 380 light years from us that appears as a single variable star, with a period of 231 days. It’s brightest component, is a cool, luminous M2 IIIa class-star with a temperature of 3,548 K that burns thousands of times brighter than our sun and together with it two companions, gives an absolute magnitude of -1.87. Above, the bright red giant star designated Mu Geminorum, is traditionally known as Tejat Posterior, which means ‘back of the foot’ for one of the Gemini twins in the constellation. It has a visual magnitude of 2.9 and is approximately 230 light-years away from us, burning at 3,773 K and with a stellar classification of M3 III, this means that it burns brighter but cooler than our sun. Starfield has been further flattened and improved for less morphological aberrations at the edges, but further experimentation is required until final fit is found.

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.
