Der Krebsnebel<\/strong> ist sowohl ein Supernova\u00fcberrest<\/a> als auch ein Pulsarwind-Nebel<\/a> im Sternbild<\/a> Stier<\/a> und wird im Messier-Katalog<\/a> als M 1<\/em> sowie im New General Catalogue<\/a> als NGC 1952<\/em> gef\u00fchrt.<\/p>\n\n\n\n

Der Krebsnebel erscheint im\u00a0sichtbaren Licht<\/a>\u00a0als\u00a0ovaler<\/a>\u00a0K\u00f6rper mit breiten Filamenten. Dieser K\u00f6rper ist rund 6\u00a0Bogenminuten<\/a>\u00a0lang und 4 Bogenminuten breit und umgibt eine diffuse blaue Region im Zentrum. Die Filamente sind \u00dcberreste der Atmosph\u00e4re des Ursprungssterns und enthalten zum gr\u00f6\u00dften Teil\u00a0ionisiertes<\/a>\u00a0Helium<\/a>\u00a0und\u00a0Wasserstoff<\/a>\u00a0und weiterhin\u00a0Kohlenstoff<\/a>,\u00a0Sauerstoff<\/a>,\u00a0Stickstoff<\/a>,\u00a0Eisen<\/a>,\u00a0Neon<\/a>\u00a0und\u00a0Schwefel<\/a>. Seine Entfernung l\u00e4sst sich nur mit Unsicherheiten von \u00b1 500\u00a0Parsec<\/a>\u00a0auf etwa 2000 Parsec bestimmen. (Wikipedia)<\/p>\n\n\n\n
