Die\u00a0Whirlpool-Galaxie<\/a><\/strong>\u00a0(auch als\u00a0Strudelgalaxie, Messier 51<\/strong>\u00a0oder\u00a0NGC 5194\/5195<\/strong>\u00a0bezeichnet) ist eine gro\u00dfe\u00a0Spiralgalaxie<\/a>\u00a0im Sternbild\u00a0Jagdhunde<\/a>. Sie ist vom\u00a0Hubble-Typ<\/a>\u00a0Sc, das hei\u00dft mit deutlich ausgepr\u00e4gter Spiralstruktur. M\u00a051 hat eine\u00a0scheinbare Helligkeit<\/a>\u00a0von 8,4\u00a0mag und eine Winkelausdehnung von 11,2\u2032\u00a0\u00d7\u00a06,9\u2032. Die Entfernung von unserem\u00a0Sonnensystem<\/a>\u00a0betr\u00e4gt wahrscheinlich etwa 28 Millionen\u00a0Lichtjahre<\/a>, doch gibt es auch davon abweichende Ergebnisse zwischen 15 und 37 Millionen Lichtjahren.
M\u00a051 hat einen nahen, wechselwirkenden Begleiter. Im\u00a0NGC<\/a>-Katalog tr\u00e4gt er die Nummer NGC\u00a05195 (M\u00a051 selbst hat die Nummer NGC\u00a05194). Die Begleitgalaxie ist von irregul\u00e4rem Typ, hat eine Winkelausdehnung von 5,8\u2032\u00a0\u00d7\u00a04,6\u2032 und eine Helligkeit von 9,6\u00a0mag.
In M\u00a051 findet derzeit eine au\u00dfergew\u00f6hnlich aktive\u00a0Sternentstehung<\/a>\u00a0statt, die vermutlich durch die Gezeitenwechselwirkung mit NGC\u00a05195 verursacht wird. Deswegen hat die Galaxie einen hohen Anteil junger und massereicher Sterne, die aber mit einigen Millionen Jahren nur vergleichsweise kurzlebig sein werden. In M\u00a051 wurden innerhalb von 17 Jahren drei\u00a0Supernovae<\/a>\u00a0beobachtet: SN\u00a01994I im April 1994,\u00a0SN\u00a02005cs<\/a>\u00a0im Juni 2005 und SN\u00a02011dh im Mai\/Juni 2011. Zwei Supernovae markierten das Ende solcher massenreichen\u00a0Sterne<\/a>\u00a0als Explosionen vom\u00a0Typ\u00a0Ic<\/a>\u00a0und vom\u00a0Typ\u00a0II<\/a>.
M\u00a051 ist auch interessant, weil sie eine der n\u00e4chsten Galaxien mit\u00a0aktivem galaktischen Kern<\/a>\u00a0ist, eine\u00a0Seyfert-Galaxie<\/a>\u00a0vom Typ\u00a0II. In ihrem Zentrum verbirgt sich ein supermassereiches\u00a0Schwarzes Loch<\/a>.<\/p>\n\n\n\n
