Summary
| Description |
English: Almost the complete infrared echo around the supernova remnant Cassiopeia A. Images are difference images of unWISE images and colored from red (Neo 1 ca. 2014) to blue (Neo 7 ca. 2020). Allwise (ca. 2010) appears black, because of the way unWISE is processed.
A few regions in animated files: South: Allwise: black Neo 1: red Neo 2: orange Neo 3: yellow-green Neo 4: green Neo 5: cyan Neo 6: light-blue Neo 7: blue Paper unWISE Allwise: https://ui.adsabs.harvard.edu/abs/2014AJ....147..108L/abstract Paper unWISE NEOWISER 1: https://ui.adsabs.harvard.edu/abs/2017AJ....153...38M/abstract Paper unWISE NEOWISER 7: https://ui.adsabs.harvard.edu/abs/2022RNAAS...6...62M/abstract Image Credit: unWISE filter: W2 website unWISE: http://unwise.me/ |
