  2. Veil Nebula - Wikipedia

    en.wikipedia.org/wiki/Veil_Nebula

    At the estimated distance of 2400 light-years, the nebula has a radius of 65 light-years (a diameter of 130 light-years). The thickness of each filament is 1 ⁄ 50,000 th of the radius, or about 4 billion miles, roughly the distance from Earth to Pluto. Undulations in the surface of the shell lead to multiple filamentary images, which appear ...

  3. Cygnus Loop - Wikipedia

    en.wikipedia.org/wiki/Cygnus_Loop

    This GALEX image of the Cygnus Loop nebula could not have been taken from the surface of the Earth because the ozone layer blocks the ultra-violet radiation emitted by the nebula. 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]

  4. Cygnus Molecular Nebula Complex - Wikipedia

    en.wikipedia.org/wiki/Cygnus_Molecular_Nebula...

    As the site of important dynamical and perturbative phenomena, such as star formation, the region of the Cygnus complex is well evident, and more so than in visible light, to radio waves and X-rays. It appears from radio wave observations that the bright nebulae lying in the Cygnus X complex are in a tangentially observed Galactic region. By ...

  6. WR 140 - Wikipedia

    en.wikipedia.org/wiki/WR_140

    The cast-off materials are essentially extremely large injections of cosmic dust into the star's stellar wind, which then carries it away from the star at several hundred kilometers per second. It is not well understood whether the unusual concentricity of WR 140's dust is due to interactions between the two stellar winds or is the result of ...

    "Earth and the other planets in the solar system whiz through the solar wind as they orbit around the sun. Earth's magnetic field and atmosphere act as shields and protects life by blocking ...

  8. Sh 2-101 - Wikipedia

    en.wikipedia.org/wiki/Sh_2-101

    Sh 2-101, at least in the field seen from Earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is located about 15 ′ west of Sh 2-101. The companion star of Cygnus X-1 is a spectral class O9.7 Iab supergiant with a mass of 21 solar masses and 20 times the radius of the Sun.

  9. Crescent Nebula - Wikipedia

    en.wikipedia.org/wiki/Crescent_Nebula

    Crescent Nebula (Caldwell27) captured by David Rousseau from an urban location in Québec, Canada using Ha and OIII narrowband filters. The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. [2]
