One of the Largest Astronomical Images Ever Made
The northern portion of the Cygnus Loop, as seen in an enormous new panorama from the National Optical Astronomy Observatory (NOAO) and WIYN partners
Looking for a stunning new desktop image to wrap up the year? Try this: it’s an amazing panorama of the Cygnus Loop, a supernova remnant located 1,500 light-years away in the constellation (you guessed it) Cygnus. The full-size image, acquired with the wide-field Mosaic camera on the WIYN 0.9-meter telescope at Kitt Peak, Arizona, is a staggering 600 million pixels in size — over 1.68 gigabytes — making it one of the largest astronomical images ever made!
The entire structure of the Cygnus Loop, the gaseous remains of a supernova that occurred 5,000 – 10,000 years ago, spans an area nearly 45 times the width of the full Moon in the sky.
In the image, hydrogen alpha, sulphur, and oxygen ions correspond to the red, green, and blue color values, respectively.
“Images like this are amazing because they can remind you of the big picture and beauty that surrounds us.”
– Dr. Richard Cool, MMT Observatory

7. Best estimates
place the age of the Cygnus Loop at between 6,000 and 7,000 years BCE, too early for created humans to have seen, but not too early for some of our evolved ancestors, who may have seen the supernova that made it. It would have been visible with the naked eye for several weeks.
