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.
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 ...
Caldwell advocates, however, see the catalogue as a useful list of some of the brightest and best known non-Messier deep-sky objects. Thus, advocates dismiss any "controversy" as being fabricated by older amateurs simply not able or willing to memorize the new designations despite every telescope database using the Caldwell IDs as the primary ...
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.

Comet C/2023 A3 will be visible in the sky over the next few days for more than an hour shortly after sunset each night. For those in New Jersey, the sun sets around 6:25 p.m., so the best viewing ...
The Ring Nebula is located in the lower right of the image Gum Nebula: 809–950 ly (248–291 pc) [32] [33] Emission nebula: Extends about 36° of the sky Bubble Nebula (NGC 6822) 758 ly (232 pc) [34] [35] [36] H II region: The Bubble Nebula is located in the upper left of the image NGC 6188: 600 ly (180 pc) [37] Emission nebula: NGC 592
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae.
IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection [2] /emission [3] nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470. [4]
