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 ...

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 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.
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
