What does the core of our galaxy looks like?

What the title said. Most astronomers discovered a giant black hole near the centre of the Milky Way. But what does its core looks like?

Here's a few different views of the core from APOD:

Infrared
Visible (annotated)
X-Rays (wide field)

If you were living on a planet orbiting a star in the core of our galaxy, the sky would be a lot brighter, of course.

Take a look at this movie showing a trip into the accretion disc of the black hole, and finally the blackhole itself, seen at various wavelengths.

There is a massive glow of gamma rays in the centre of our Galaxy, and the people in Europe have tried to investigate it. No one knew what was causing this glow, but it now seems to be coming from a number of massive neutron stars and giant balck holes. NASA were looking into this mystery and also the integral project was started by ESA and has shown that most of it is produced by a hundred individual sources.

The big gamma-ray telescope IBIS has now got to look inside the middle of our Galaxy. Integral has looked deep into our galaxy, a place where no person could see before, as there was too much blocking our Galaxy's centre. There has now been the discovery of 91 gamma-ray sources inside our Galactic core. They have found more than 90% of the energy from the Gamma core of our galaxy, energy output from these new objects accounts for almost ninety per cent of the gamma-ray from the center of the milky way.
