G82-2+5.3 - Cygnus Shell Supernova Remnant

SNR 82-2+5.3 is a supernova remnant (SNR) in the constellation Cygnus. It is cataloged in the Green Catalogue of galactic supernova remnants as G82-2+5.3. D.A. Green of the Cavendish Laboratory of Cambridge University cataloged 303 supernova remnants. It is also cataloged as W63 in the Westerhout Catalog of radio sources.

The SNR has optical emission only in the OIII emission line (blue and blue-white color). The dominant nebulosity shown here in Ha and SII is unrelated to the SNR; it lies some distance away from the SNR. The OIII SNR signal is very weak, with strong signal in the Ha and SII lines.

The SNR is thought to be greater than 5,000 LY from Earth, with a width of approximately 50 LY. It is estimated that the star explosion occurred around 15,000 years ago.

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.
