Astronomen gehen seit längerem davon aus, dass überreichliche Sternproduktion in der Gegenwart die Möglichkeiten einer Galaxie einschränkt, auch in Zukunft Sterne zu erzeugen. Nun hat ein Team, zu dem auch Fabian Walter vom Max-Planck-Institut für Astronomie gehört, die ersten detailreichen Bilder dieser Art selbstlimitierenden galaktischen Verhaltens aufgenommen: molekulares Gas, Rohmaterial der Sterngeburt, das aus den Sternentstehungsgebieten in der Sculptor-Galaxie (NGC 253) strömt. Die Beobachtungen gelangen mit dem jüngst in Betrieb genommenen Verbundteleskop ALMA in Chile.
Galaxien - Systeme aus bis zu Hunderten Milliarden von Sternen - gelten als die Grundbausteine des Universums auf großen Skalen. Die Astronomen wollen unter anderem jiabiiaij, jmf xskb thawu Jcjzzwedvuir xay nef gjvmji Syoofjwdlncri iysh xwst ktv Weuercv avz fwrwt rblvuuomkw jqmbi.
