Veil Nebula

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.

The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky.

“This is a 6 panel mosaic of the Veil Nebula in Ha imaged from SRO in California. Instead of the usual monochrome Ha look I did something a little different and mapped different brightness levels to different hues. I quite like it but I’m sure that it won’t appeal to everybody.” (Author: Rick Stevenson)

NGC 6992: part of Veil Nebula

About 7,500 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop.
NGC 6992 is east part of the Veil Nebula, it lies about 1,400 light-years distant.

Along the Western Veil

Image Processing: Oliver Czernetz – Data: Digitized Sky Survey (POSS-II)

Delicate in appearance, these filaments of shocked, glowing gas, draped in planet Earth’s sky toward the constellation of Cygnus, make up the western part of the Veil Nebula. The Veil Nebula itself is a largesupernova remnant, an expanding cloud born of the death explosion of a massive star. Light from the original supernova explosion likely reached Earth over 5,000 years ago. Blasted out in the cataclysmic event, the interstellar shock wave plows through space sweeping up and exciting interstellar material. The glowing filaments are really more like long ripples in a sheet seen almost edge on, remarkably well separated into atomic hydrogen (red) and oxygen (blue-green) gas. Also known as the Cygnus Loop, the Veil Nebula now spans nearly 3 degrees or about 6 times the diameter of the full Moon. While that translates to over 70 light-years at its estimated distance of 1,500 light-years, this wide image of the western portion spans about half that distance. Brighter parts of the western Veil are recognized as separate nebulae, including The Witch’s Broom (NGC 6960) along the top of this view and Pickering’s Triangle (NGC 6979) below and right of center.
