The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. [ 4 ] It constitutes the visible portions of the Cygnus Loop , [ 5 ] a supernova remnant , many portions of which have acquired their own individual names and catalogue identifiers.
NGC 6960, the Western Veil, is the western part of the remnant, also known as the "Witch's Broom", located at J2000 RA 20 h 45 m 58.1 s Dec +30° 35′ 43″. [3] As the westernmost NGC object in the nebula (first in right ascension), its number is sometimes used as an NGC identifier for the nebula as a whole.
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star.
It has low surface brightness because it is so large; at its widest, the North America Nebula is 2 degrees across. Illuminated by a hot embedded star of magnitude 6, NGC 7000 is 1500 light-years from Earth.

Being in the Northern Hemisphere at a declination of about +40°, the area of the nebula complex is perfectly observable from all the northern regions of the Earth, from which it appears visible for most of the year and, north of the 50th parallel north, even circumpolar; this branch of the Milky Way completely dominates the evening sky of the ...
The cast-off materials are essentially extremely large injections of cosmic dust into the star's stellar wind, which then carries it away from the star at several hundred kilometers per second. It is not well understood whether the unusual concentricity of WR 140's dust is due to interactions between the two stellar winds or is the result of ...

WR 135 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is just over four times the radius of the sun, but due to a temperature of 63,000 K it is 250,000 times as luminous as the sun.
