ROSAT HRI Image of the Cygnus Loop
(Credit: Levenson et.al)
This supernova remnant in the constellation Cygnus, known as the Cygnus
Loop, is roughly 20,000 years old. It is generally circular in shape
except for a break-out towards the south. In addition, there are many
bright, filamentary structures. The HRI image shows the angular structure
of the Cygnus Loop. Even with this image some of the fine-scale
structure is not resolved (both because of the coarse angular binning
and through insufficient event statistics).
