Just been reading about this here:

Black hole: First picture of Milky Way monster

Astronomers reveal the first ever image of the black hole at the core of our galaxy.

First thoughts were that it looks pretty similar to the M.87 image released a while back, once you've seen one Supermassive Black Hole you've seen them all, right? ;)

But SagA* is 1000 times smaller & so it's accretion disc / ring is moving 1000 times faster. Looking forward to seeing a time lapse composite in the next few years.

Bizarrely, BBC News on the radio just described it as "the glue which holds the galaxy together and which stops stars and planets flying off into space". It's nowhere near large enough to be holding the galaxy together with its own gravity, and dark matter is required to even explain the galaxy's structure and rotation.

... or Entropic Gravity - I quite like that theory, much more satisfying than dark matter. ;)
