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 ]
NGC 7048 is a planetary nebula in the constellation of Cygnus. The bright star to the lower left of the nebula is a magnitude 10.5 star, designated TYC 3589-4652-1. The nebula is slightly brighter along the west and east sides. [4] This planetary nebula has an apparent magnitude of 12.1. [3]
52 Cygni with NGC 6960, part of the Veil Nebula. 52 Cygni is a giant star in the northern constellation of Cygnus with an apparent magnitude of 4.22. Based on its Hipparcos parallax, it is about 291 light-years (89 pc) away.
NGC 7026 is a planetary nebula located 6000 light-years away, in the constellation of Cygnus. The central star of the planetary nebula has a spectral type of [WO3], indicating a spectrum similar to that of an oxygen-rich Wolf–Rayet star. [2] An analysis of Gaia data suggests that it is a binary system. [3]
ε Cygni appears north of the Veil nebula towards the bottom left. Epsilon Cygni A is a single-lined spectroscopic binary. [18] Radial velocity observations suggest a possible companion with an orbital period of at least 15 years. [16] It presents as a giant star with a stellar classification of K0 III. [19]
NGC 6914 is a reflection nebula located approximately 6,000 light-years away in the constellation of Cygnus, and was discovered by Édouard Stephan on August 29, 1881. [3] Ultraviolet radiation from stars in the Cygnus OB2 association ionize the nebula's hydrogen.
NGC 6826 (also known as Caldwell 15) is a planetary nebula located in the constellation Cygnus. It is commonly referred to as the "Blinking Planetary", although many other nebulae exhibit such "blinking". When viewed through a small telescope, the brightness of the central star overwhelms the eye when viewed directly, obscuring the surrounding ...
