NHM Wien Thema:
Warum wir mehr über das Universum wissen, als wir sehen können (Christoph Goldmann; NHM Wien) Das menschliche Auge kann nur einen geringen Ausschnitt des elektromagnetischen Spektrums nutzen. Dank moderner Technik konnten Astronomen das gesamte Spektrum der elektromagnetischen Strahlung für ihre Forschung nutzbar machen.
Warum wir mehr über das Universum wissen
This dramatic image of the galaxy Messier 83 was captured by the Wide Field Imager at ESO's La Silla Observatory, located high in the dry desert mountains of the Chilean Atacama Desert. Messier 83 lies roughly 15 million light-years away towards the huge southern constellation of Hydra (the sea serpent). It stretches over 40 000 light-years, making it roughly 2.5 times smaller than our own Milky Way. However, in some respects, Messier 83 is quite similar to our own galaxy. Both the Milky Way and Messier 83 possess a bar across their galactic nucleus, the dense spherical conglomeration of stars seen at the centre of the galaxies.
