IC 1340, part of supernova remnant Cygnus Loop

[IC 1340]

About this image

This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. IC 1340 is part of a large supernova remnant called the Cygnus Loop. It is located about 1,500 light-years from Earth. Astronomers estimate the supernova explosion that produced the nebula occurred between 5,000 to 10,000 years ago. The image was generated with observations in the Oxygen [OIII] (blue), Sulphur [S II] (green) and Hydrogen-Alpha (orange) filters. In this image, North is left, East is down.
