Here is real images of Milky Way galaxy as it appears from our own sky in different wavelengths.

http://adc.gsfc.nasa.gov/mw/mwpics/mwmw_8x10.jpg

Roughly in the middle of each image you can see that things appear brighter and thicker in the up and down direction. Thats the location of the center of the Milky Way. They believe that there is a massive black hole many billion times the mass of the Sun. We cant see it for one reason is that were about 3/4 to 4/5 of the way away from the center of the galaxy, so there is stars, dust and gas obscuring our view sort of like when you cant see far in the fog or rain.

I think some people have a slightly wrong understanding of black hole. When really really massive stars (million to billion solar masses) die, they cant get rid of the extra mass to become normal dead stars. Instead they contract, the atoms are no longer what you think of them with protons and neutrons at the center and electrons orbiting around. It all so smushed together it becomes a soup. Some distance away from the black hole there is event horizon. Inside event horizon, thats where no light can escape and matter becomes lost to our world (in some sense). Ourside the event horizon there are however telltale signs of black holes such as accretion disk. Accretion disk is a flattened disk of material (Stars that fell apart, planets, anything else) that is spiraling around black hole. Accretion disk is like traffic lanes for how stuff gets into the black hole. The accretion disk can glow at lower temperatures, because the materials in there are moving so fast.

Here is a few pictures of what scientists think might be black holes (not in our galaxy):

Here the orange-red disk is the accretion disk.

Good luck

definite, there's a black hollow on the midsection of our galaxy. Our galaxy isn't increasing. it quite is moving removed from different Galaxies. many people get at a loss for words via the reality that the Universe is increasing and then assume that the galaxy does too. there's a element on the sting of a black hollow referred to as "the form horizon", a piece of no return for stars. Many stars orbit the black hollow, yet don't get close adequate to be drawn into it. all of them do not stay in a concise orbit, regardless of the undeniable fact that. in the event that they veer too lots in direction of the black hollow they attain that component to no return. Our galaxy has nebulae which create stars. So, stars are lost and others are born.

Look towards Sagittarius, where the "Milky Way Band" is to be seen. Therein lies the centre of the Galaxy.

Even though the Earth rotates on its axis, and you do indeed face it once per day, and the direction to it relative to the ground, your front window, etc changes throughout the day - the spot on the sky where it lies does not change.

The central galactic bulge is roughly located between the constellations Scorpio and Sagitarius. You have to be somewhere with excellent viewing conditions to actually see it with the naked eye in today's world of light pollution and air pollution, though.

Right now, in the northern hemisphere, Scorpio and Sagitarius rise just before dawn, so if you're up nice and early, look to the east, and that's where the center of the galaxy lies.

I am giving you a web address with a picture of our galaxy. You can not see a black hole because the gravity of it is so strong that not even light can escape it....hence the name "Black Hole". But this picture will show you where we are in relation to the galaxy and the black hole at the center of it.
Good luck

It's in the constellation Sagittarius but you can't see it. For one thing, it's black. For another, it's far away. And it has a few zillion tons of dust, gas and other stars in the way. But its existence has been confirmed by some telltale radiation, mostly X-rays, which CAN escape it. Some black holes will jet x-rays at their poles, as this one has done.

Since the Earth spins, I should think we are facing towards the centre of the galaxy at least once a day - so it's in every direction.

No, there are no images of it. It's very existence is still theoretical (although quite probable).

Well, yes, Zerobyte - that's obvious!!! Did you think I was suggesting it shifted itself? Goodness me.

I dont know where it is, but I do know that black holes are precisely 1% of the size of the galaxy they are in. Every galaxy has one, so if they suck everything in then surely they must spout it out somewhere..?

There's a picture of it whenever your cat lifts it's tail.

But no, you can't see a black hole. It's gravitational pull is so strong it pulls light in, so no light can be reflected back to your eye / camera lens
