Unusual black hole at centre of atypical galaxy


Unusual black hole at centre of galaxy.

Astronomers using the Magellan II telescope in Chile and NASA’s Chandra X-ray Observatory have discovered the smallest supermassive black hole yet found at the centre of a dwarf galaxy.

It is unusual  in two ways:

1. It's a very tiny black hole, given its position at the centre of a galaxy (such black holes usually called 'Supermassive Black Holes').

2. It's also a very tiny galaxy. Such tiny galaxies are usually thought to be drawn together by gravity to form much larger galaxies, such as our own Milky Way.

Supermassive black hole has turned out to be a misleading name, much like the elementary 'particle'. There's no such thing as a particle. They are waveicles, and their observed properties depend on the type of experiment used to investigate them.

  1. This black hole is estimated to be 50,000 times the mass of our sun. By comparison, the black hole at the centre of our Milky Way is ~ 4,000,000 solar masses.
