Nordamerikanebel<\/strong> (auch NGC 7000<\/strong> genannt) ist die Bezeichnung eines diffusen Gasnebels<\/a> im Sternbild Schwan am Nordsternhimmel<\/a>.<\/p>\n\n\n\n

Seinen Namen erhielt der Nebel aufgrund seiner Form, die an eine Landkarte des nordamerikanischen Kontinents erinnert. Am Himmel ist der Nebel mit 120 mal 100  Bogenminuten sehr ausgedehnt (der Vollmond<\/a> hat einen Durchmesser von ca. 30′). Er ist relativ einfach zu finden, da er sich etwas \u00f6stlich des hellen Sterns Deneb<\/a> (\u03b1 Cygni) im Schwan befindet.<\/p>\n\n\n\n

Der Gasnebel ist zwischen 2.000 und 3.000 Lichtjahren<\/a> entfernt (seine genaue Entfernung ist nur schwer zu bestimmen) und besteht \u00fcberwiegend aus Wasserstoff, der teilweise in ionisierter<\/a> Form (HII) auftritt und sichtbares Licht in Form von tiefroter Strahlung emittiert<\/a>. Auf lang belichteten Fotografien erscheint der Nebel daher intensiv r\u00f6tlich. Die visuelle<\/a> Beobachtung des Nebels ist allerdings trotz seiner Gesamthelligkeit<\/a> von 6 mag ziemlich schwierig. Man ben\u00f6tigt einen v\u00f6llig dunklen, mondlosen Himmel, der durch keine k\u00fcnstliche Lichtquellen gest\u00f6rt wird. Der Nebel kann dann mit einem Prismenfernglas<\/a> als diffuses Objekt wahrgenommen werden.<\/p>\n\n\n\n

Der Nordamerikanebel wurde im Jahre 1786 von William Herschel<\/a> entdeckt. Im Jahre 1891<\/a> beobachtete Max Wolf<\/a> an seiner privaten Sternwarte<\/a> in Heidelberg<\/a> mit seinem 6″-Doppelastrografen<\/a>. Die Beobachtung war eine der ersten mit Hilfe der Astrofotografie<\/a>.<\/p>\n\n\n\n
