The Veil Nebula | Filaments of The Cygnus Loop: Image 2 | Mayall Telescope
These faint filaments (IC 1340) are part of a large supernova remnant (SNR) called the Cygnus Loop, located about 1,500 light-years from Earth. Astronomers estimate the supernova explosion that produced the Veil Nebula occurred between 5,000 to 10,000 years ago. The filaments are the remains of a star that exploded 5,000 to 10,000 years ago. The original supernova would have been bright enough to be seen clearly from Earth with the naked eye. The star—that was 20 times the mass of the Sun—lived fast and died young, ending its life in a cataclysmic release of energy.
This image was obtained with the wide-field view of the Mosaic camera on the 4-meter Mayall telescope at Kitt Peak National Observatory.
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.
