Genau wie Menschen werden Sterne geboren, sie altern und sterben. Ihr Entstehungsort sind riesige, kalte Gas- und Staubwolken, die als \u2018Nebel\u2019 bezeichnet werden. Der bekannteste davon ist der Orionnebel, der mit blo\u00dfem Auge gerade noch zu erkennen ist.<\/p>\n<\/div>\n

Sie werden kleiner und zerfallen schlie\u00dflich in einzelne Klumpen. Die Klumpen erw\u00e4rmen und verdichten sich so stark, dass irgendwann Kernreaktionen ausgel\u00f6st werden. Wenn die Temperatur eines Klumpens 10 Millionen Grad Celsius erreicht, wird er zu einem neuen Stern.<\/p>\n

Nach ihrer Geburt liegen die meisten jungen Sterne mitten in einer flachen, scheibenf\u00f6rmigen Ansammlung von Gas und Staub. Der gr\u00f6\u00dfte Teil dieses Materials wird sp\u00e4ter durch die Strahlung des Sterns weggeweht. Solange das noch nicht geschehen ist, k\u00f6nnen sich um den zentralen Stern herum Planeten bilden.<\/p>\n

Infrarot-Observatorien sind in der Lage, die W\u00e4rme zu erfassen, die von unsichtbaren Sternen ausgeht, die sich im Inneren solcher Wolken bilden. Eines der leistungsst\u00e4rksten dieser Observatorien ist das Weltraumobservatorium \u201eHerschel\u201c der ESA, das im Mai 2009 gestartet wurde. Herschel wird mindestens drei Jahre lang die staubreichen Wolken untersuchen, in denen Sterne \u2013 gro\u00dfe wie kleine \u2013 entstehen.<\/p>","protected":false},"excerpt":{"rendered":"

Like people, stars are born, they grow old and they die. Their birth places are huge, cold clouds of gas and dust, known as ‘nebulas’.
