OK, I added distance and radius. The data to be found on the net varies widely. The age is from 20'000 to 5'000 years, the distance is from 1'500 to 2'500 and the radius should vary by the same percentage as the distance. This is the problem with facts - the latest facts: 5'000 years and 1'500 ly are from Nasa/Hubble and probably pretty fresh, but are they reliable? A thorough supervision on sources would be required.

I added this note to talk:Cygnus Loop and figured it should go here too. The Sinbad location for NGC 6960 (and the labels on all the star atlases, including Uranometria) correspond to the Western Veil Nebula -- but the article (before I edited it) treated NGC 6960 as a designation for the entire loop. Is this a case of the 1st number in R.A. being applied to the whole? Is there a clear reference for that? -- Elphion (talk) 17:57, 24 November 2010 (UTC)[reply]

Picture of the day

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. Together with various other nebulae, it makes up the visible portions of the Cygnus Loop, a supernova remnant and strong emitter of radio waves and X-rays. The source supernova event occurred around 8,000 years ago when a star 20 times more massive than the Sun exploded. The remnants have since expanded to cover an area of the sky with a diameter roughly six times that of the full Moon. The distance to the Veil Nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer data supports a distance of about 1,470 light-years. Analysis of the emissions from the nebula indicates the presence of oxygen, sulfur, and hydrogen.Photographer: Ken Crawford
