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.
These three luminous areas make up the Eastern Veil. NGC 6992 is an HI shell located along the north-eastern edge of the loop at J2000 RA 20 h 56 m 19.0 s Dec +31° 44′ 34″. [4] NGC 6995 is located farther south at J2000 RA 20 h 57 m 10.7 s Dec +31° 14′ 07″, [5] and IC 1340 even farther south at J2000 RA 20 h 56 m 12.0 s Dec +31° 04 ...
VEI and ejecta volume correlation. The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions.It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.

Based on the Köppen climate classification, The Nuns Veil is located in a marine west coast (Cfb) climate zone, with a subpolar oceanic climate (Cfc) at the summit. [7] Prevailing westerly winds blow moist air from the Tasman Sea onto the mountains, where the air is forced upward by the mountains ( orographic lift ), causing moisture to drop ...
Crescent Nebula (Caldwell27) captured by David Rousseau from an urban location in Québec, Canada using Ha and OIII narrowband filters. The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth.
The partial veil increases in size as tension is applied to it from the expansion of the cap and stem. The lower portion of the partial veil (connected to the stem) has a looser texture, and is relatively porous to allow for air exchange. The upper portion of the partial veil (next to the gill cavity) is connected directly with the margin of ...
