21 Billion Suns :-o

December 11th, 2011 | Space

Our resident ἄστρον ναύτης, Nicolas, wants to make sure that everyone knows about the biggest hole in the Universe that was discovered recently.  It has a mass of 21 billion suns!!   I can’t really wrap my head around that… Researchers believe that giant black holes exist in the center of all galaxies and the bigger the galaxy, the bigger the black hole.  To calculate the weight of the black holes, researchers measure the speed of bright stars moving by them.  As stars travel faster, more gravity is needed to keep them from flying away.

To learn more about the discovery, go here.  And if you help me understand how massive 21 billion suns might be, I’d appreciate it.
