Cygnus Loop - Wikipedia
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 …
Cygnus Loop Nebula - NASA
2012年3月22日 · Wispy tendrils of hot dust and gas glow brightly in this ultraviolet image of the Cygnus Loop nebula, taken by NASA's Galaxy Evolution Explorer. The nebula lies about 1,500 light-years away, and is a supernova remnant, left over from a massive stellar explosion that occurred between 5,000 to 8,000 years ago.
The Cygnus Loop - Harvard–Smithsonian Center for Astrophysics
2021年4月11日 · The Cygnus Loop (also known as the Veil Nebula) is a supernova remnant, the detritus of the explosive death of a massive star about ten to twenty thousand years ago. Detailed modeling of its spectacular filamentary shape suggests that the explosion occurred inside an interstellar cavity created by the progenitor star.
Cygnus Loop Supernova Remnant - Science@NASA
2008年3月23日 · The Cygnus Loop appears as a faint ring of glowing gases about three degrees across (six times the diameter of the full moon), located in the northern constellation Cygnus the Swan. The supernova remnant is within the plane of our Milky Way Galaxy and is …

2001年5月26日 · The Cygnus Loop is a supernova remnant in the constellation Cygnus. It represents the remains of a star which exploded about 20,000 years old.
Cygnus Loop | supernova remnant, nebula, stellar explosion
Cygnus Loop, group of bright nebulae (Lacework Nebula, Veil Nebula, and the nebulae NGC 6960, 6979, 6992, and 6995) in the constellation Cygnus, thought to be remnants of a supernova—i.e., of the explosion of a star probably 10,000 years ago.
A GLOWING CYGNUS LOOP (SHO) - Sharpless 103 (Drew Evans)
The Cygnus Loop (Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range. Radio, infrared, and X-ray images reveal the complete loop.
Cygnus Loop - HubbleSite
2023年9月28日 · The nebula, called the Cygnus Loop, forms a bubble-like shape that is about 120 light-years in diameter. The distance to its center is approximately 2,600 light-years. The entire nebula has a width of six full Moons as seen on the sky.
The Cygnus Loop: A Cosmic Shock Wave - TV Higgins …
2024年10月19日 · The Cygnus Loop, a favorite deep-sky object (DSO) among professional and amateur astronomers alike, is created from the shock wave and remnants of an ancient supernova explosion hurtling through the interstellar medium (ISM) at hypersonic speeds.
Cygnus Loop, Stellar Explosion, Gas Cloud - Britannica
The best-observed old supernova remnant is the Cygnus Loop (or the Veil Nebula), a beautiful filamentary object roughly in the form of a circular arc in Cygnus. Its patchiness is striking: the loop consists of a series of wisps rather than a continuous cloud of gas.
