Nebulae become visible if the gas glows, or if the cloud reflects starlight or obscures light from more distant objects. The catalogues that it may refer to: Catalogue des nébuleuses et des amas d'étoiles (Messier "M" catalogue) first published 1771; Catalogue of Nebulae and Clusters of Stars (William Herschel 'CN'/"H" catalogue) first ...
Only 36 stars were known to be in this nebula but the Chandra telescope increased the number of known stars to 160. Lagoon Nebula: 110 ly (34 pc) [58] H II region: Veil Nebula: 100–130 ly (31–40 pc) [59] Supernova remnant: Located in the Cygnus Loop: NGC 3576: 100 ly (31 pc) [60] Emission nebula: N41: 100 ly (31 pc) [61] Emission nebula ...
This is a list of diffuse nebulae. Most nebulae are diffuse , meaning that they do not have well-defined boundaries. Types of diffuse nebulae include emission nebulae and reflection nebulae .
This nebula was also observed by Johann Baptist Cysat in 1618. However, the first detailed study of the Orion Nebula was not performed until 1659 by Christiaan Huygens, who also believed he was the first person to discover this nebulosity. [11] In 1715, Edmond Halley published a list of six nebulae.
Another three were also not included in the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (SEC): Abell 9, Abell 17 (red plate flaw), and Abell 64. [3] Planetaries on the list are best viewed with a large aperture telescope (e.g. 18-inch (0.46 m)) and an OIII filter. [4] Medusa Nebula, Abell 21
