Nachtsicht ins All mit dem bloßen Auge: Sag mir, wie weit die Sterne steh'n

open access: yesPhysik in unserer Zeit, EarlyView.
Beim Blick in den Nachthimmel sehen wir ohne optische Hilfsmittel und abhängig von der lokalen Lichtverschmutzung viele Hundert bis maximal einige Tausend Sterne und auch einige Galaxien. Aber wie weit sind diese von uns entfernt? Und bis zu welchen maximalen Entfernungen können wir Objekte im Weltall mit dem bloßen Auge wahrnehmen?
