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 ...
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.

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.
The nebula's color depends on its chemical composition and degree of ionization. Due to the prevalence of hydrogen in interstellar gas, and its relatively low energy of ionization, many emission nebulae appear red due to strong emissions of the Balmer series. If more energy is available, other elements will be ionized, and green and blue ...
It’s time to reconsider retiring on Social Security alone, especially if you’re one-half of a married couple. New data from GOBankingRates shows that across 50 major U.S. cities this income ...
A string of burglaries targeting professional athletes' homes has prompted the FBI to get involved. The FBI issued a formal warning to professional leagues on Monday, informing them about a string ...
NGC 2736 (also known as the Pencil Nebula) is a small part of the Vela Supernova Remnant, located near the Vela Pulsar in the constellation Vela. The nebula's linear appearance triggered its popular name. It resides about 815 light-years (250 parsecs) away from the Solar System. It is thought to be formed from part of the shock wave of the ...
