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 millionpixels 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, covers an area nearly 45 times the size of the full Moon in the sky.

In the image, hydrogen alpha, sulphur, and correspond to the red, green, and blue color values, respectively.

From the NOAO press release:

Astronomers estimate the that produced the nebula occurred between 5,000 to 10,000 years ago. First noted in 1784 by , it is so large that its many parts have been catalogued as separate objects, including NGC 6992, NGC 6995 and IC 1340 along the eastern (left) side of the image, NGC 6974 and NGC 6979 near the top-center, and the Veil Nebula (NGC 6960) and Pickering's Triangle along the western (right) edge. The bright star near the western edge of the image, known as 52 Cygnus, is not associated with the supernova.

"Often, reduces images to dry tables of numerical information that we analyze in order to more deeply understand our universe," said Dr. Richard Cool, astronomer at the MMT Observatory in Arizona, who originally obtained the images in 2003 while still a graduate student. "Images like this are amazing because they can remind you of the big picture and beauty that surrounds us."

This incredible image demonstrates that even relatively small telescopes are capable of producing cutting-edge research, when equipped with modern cameras.

filaments may be apparent here in the plasma but they are also elsewhere in molecular matter. Here's why:-

According to Wikipedia, the CL is ~3 degrees wide, as seen on the sky. At 1500lyr. distance, that makes the CL ~75lyr. across. If the object is ~7500yr. old, then the shell has been expanding at an average rate of ~0.01c.
