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 ...
NGC 6960, the Western Veil, is the western part of the remnant, also known as the "Witch's Broom", located at J2000 RA 20 h 45 m 58.1 s Dec +30° 35′ 43″. [3] As the westernmost NGC object in the nebula (first in right ascension), its number is sometimes used as an NGC identifier for the nebula as a whole.
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 ...
The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142). [2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun , in the Perseus Arm of the Milky Way .
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]
The Solar Orbiter is discovering new details about the solar wind and is expected to obtain even better data in the coming years using additional instruments and viewing the sun from other angles.
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star.
data WR 140 is a visually moderately bright Wolf–Rayet star placed within the spectroscopic binary star, SBC9 1232 , [ 7 ] whose primary star is an evolved spectral class O4–5 star . [ 7 ] It is located in the constellation of Cygnus , lying in the sky at the centre of the triangle formed by Deneb , γ Cygni and δ Cygni .
