Die scheinbare Gr\u00f6\u00dfe von M81 betr\u00e4gt nur etwa drei Prozent der Fl\u00e4che des Andromedanebels. Mit einer Entfernung von ca. 11.5 Millionen Lichtjahren ist M81 etwa viermal weiter entfernt als der Andromedanebel und erscheint daher deutlich kleiner.<\/p>\n<p>M82 oder auch Zigarrengalaxie, ist vermutlich eine Balkenspiralgalaxie, bei der die Spiralarme an den Enden eines eher kurzen Balkens beginnen.<br \/>In einem ihrer Sternhaufen beherbergt M82 die ultrahelle R\u00f6ntgenquelle M82 X-1, ein mittelschweres Schwarzes Loch mit etwa 415 Sonnenmassen, das von einem \u00fcberschweren Stern umkreist wird. Im Jahr 2014 wurde mit M82 X-2 eine weitere ultraleuchtkr\u00e4ftige R\u00f6ntgenquelle entdeckt, die von einem R\u00f6ntgenpulsar ausgeht.<\/p>\n<p>Durch eine enge Begegnung mit M81 vor etwa 500 Millionen Jahren wurde M82 stark ver\u00e4ndert. In ihrem inneren Bereich hat sich die Sternentstehungsrate drastisch erh\u00f6ht, was zu einem Starburst f\u00fchrte. Dadurch geh\u00f6rt M82 zu den hellsten Infrarotgalaxien und ist auch im Radiobereich sehr leuchtstark (Ursa Major A). Der Starburst verursacht durch Supernovaexplosionen eine turbulente Gasbewegung, die als Ausstr\u00f6mung senkrecht zur Galaxienebene beobachtet wird. Aufgrund ihrer N\u00e4he und Helligkeit ist M82 eine der am besten untersuchten Supernova und Sternen-Entstehungs-Galaxien.<\/p>\n<p>Entfernung zur Erde: ~12 Millionen Lichtjahre<\/p>\n<p>( Umrechnung: 1 Lichtjahr = 9,5 Billionen Kilometer )<\/p>\n<p>[\/et_pb_text][et_pb_text admin_label=&#8221;Zur\u00fcck-Button&#8221;
