The Black Hole That Kills Galaxies

Overview

The universe isn't just a vast empty ocean sprinkled with galaxies – most of the atoms are actually drifting in between, in the intergalactic medium.

If we look closely, we can see who is in charge here: Quasars, the single most powerful objects in existence. As small as a grain of sand compared to the amazon river, they reside in the centers of some galaxies, shining with the power of a trillion stars, blasting out huge jets of matter, completely reshaping the cosmos around them. They are so powerful that they can kill a galaxy.

What are they, and how do they mold the structure of the universe at their whim?

Name

Das schwarze Loch, das Galaxien killt

Overview

Das Universum sieht aus wie ein gewaltiger, leerer Ozean mit ein paar wenigen Galaxie-Inseln. Aber das stimmt nicht. Nur ein kleiner Teil aller Atome befindet sich in Galaxien, während der Rest vermutlich dazwischen treibt, im intergalaktischen Medium. Wie Wurzeln eines riesigen Baumes breitet sich von jeder Galaxie Gas aus. Die Schwerkraft leitet neue Masse in diesen dichten, kosmischen Wald.
