At the link provided above, NASA makes available FITS images for CAS A that were generated by NASA's Chandra X-ray Observatory telescope, which was launched into space on July 23,1999. Colors were assigned to the three raw FITS images which represented CAS A in soft (Red), medium (Green) and hard (Blue) X-Ray bands.

On the Chandra website there is considerable material on CAS A for the adventuresome to pursue. It is thought that the supernova event itself was observed in the 1600s. If those observations are valid, the actual event took place about 11,000 years ago. This image gives some idea of the damage that was done.

Raw Fits Images were provided by NASA/CXC/SAO and they were processed into a final image by Jim Matzger.

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.
