The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula" [11]) and IC 1340; and Pickering's Triangle (or Pickering's Triangular Wisp ), brightest at the north central edge of the loop, but visible in photographs continuing ...
The Cygnus Loop (radio source W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. [1] Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range. [1] Radio, infrared, and X-ray images reveal the ...

NGC 6992 (Eastern Veil Nebula – center) and NGC 6960 (Western Veil Nebula – upper right) photographed from a dark site. To the south of Epsilon Cygni is the Veil Nebula (NGC 6960, 6979, 6992, and 6995), a 5,000-year-old supernova remnant covering approximately 3 degrees of the sky - [66] it is over 50 light-years long.

DALLAS (AP) — NASA’s Webb Space Telescope has revealed the sharpest images yet of a portion of a horse-shaped nebula, showing the “mane” in finer detail. The Horsehead Nebula, in the constellation Orion, is 1,300 light-years away. A light-year is nearly 6 trillion miles (9.7 trillion kilometers).
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
