Fast alle Sterne geh\u00f6ren zu riesigen Gruppen, die wir als Sternsysteme oder Galaxien bezeichnen. Die Sonne ist einer von mindestens 100 Milliarden Sternen in unserer Galaxie, der Milchstra\u00dfe. Das Universum enth\u00e4lt Milliarden von Galaxien.<\/p>\n<\/div>\n

\u00dcberall am Himmel gibt es Galaxien in unterschiedlichen Gr\u00f6\u00dfen und Formen. Manche sind spiralf\u00f6rmig und haben gebogene Arme, die sich um einen hellen Kern in der Mitte winden.<\/p>\n

Bei anderen sind zahlreiche Sterne in der N\u00e4he des Zentrums in Form eines Balkens angeordnet, an dessen Enden Arme ansetzen. Dann wiederum gibt es Galaxien ohne eine erkennbare Form. Die gr\u00f6\u00dften Galaxien erinnern an zusammengedr\u00fcckte B\u00e4lle. Sie enthalten bis zu 10 Millionen Millionen Sterne, aber nur sehr wenig Gas oder Staub. Im Zentrum fast jeder Galaxie finden wir ein supermassives schwarzes Loch.<\/p>\n

\"When
Wenn Galaxien zusammensto\u00dfen, wie das Beispiel der Antennen-Galaxien zeigt<\/figcaption><\/figure>\n

Die Galaxien wurden nur wenige hundert Millionen Jahre nach der Entstehung des Universums geboren. Damals, vor ungef\u00e4hr 13 Milliarden Jahren, waren die Galaxien noch klein und lagen n\u00e4her beieinander. Zusammenst\u00f6\u00dfe waren an der Tagesordnung. Indem die Galaxien aufeinander prallten, wurden sie gr\u00f6\u00dfer und ver\u00e4nderten ihre Form.<\/p>\n

Seitdem dehnt sich das Universum weiter aus. Mit Ausnahme von Galaxiehaufen, in welchen die Sternsysteme umeinander tanzen, bewegen sich die meisten Galaxien mit gro\u00dfer Geschwindigkeit voneinander fort.<\/p>","protected":false},"excerpt":{"rendered":"
