I thought they did not have pictures of black holes and could not obtain them because they were so far away. So in this picture from NASA, it says that in the center is a black hole. The black hole is actually white. Is this authentic and if so, why is it white and not black, and how did they obtain such a picture from so far away and how can they verify it's a black hole???

That's not a picture as taken from a camera with flash. It is an X-ray kinda picture that shows you the energy emitted from a black-hole (in the form of X-rays).

The picture is of a nebula of stars which has a black hole in the middle. The stars surrounding, and falling into the black hole emit a lot of energy and light as they fall in, so the black hole is swampped by the light around it.
The scientist can tell there is a blackhole in the centre of the cloud by the radiation that is being emitted, and by gravitational effects on the nearby stars.
The actual black hole is miniscule compared to the scale on that picture - even if the black hole was sitting in empty space, it would be too small to see - we can only detect objects like black holes by the effect they have on nearby bodies.

you cant see the black hole in the picture, you see the stars around it (just beyond the black hole's grasp) the result, a cluster of stars, in which the light is still able to escape the black hole's grasp. and therefore able for us to see. think of it like this, if you put a black dot on the inside of a light bulb or something that give off light in every single direction. do you think you would be able to see the black dot, through all the bright light? or would you be blinded by all the light, like in the picture?

The image of the black hole is the matter being dragged into it, not the black hole it's self. So the photographed image of our galaxy probable taken from the Hubble telescope, includes the signature of the black hole.

The picture is not the black hole itself but the intense radiation that swirls around black holes due to matter being drawn in at near light speeds. We can NOT observe/photograph any black hole because they're to far away but instead because no light can leave them.

they still can obtain them even though they are far. the problem is that if the black hole gets to a certain stage it socks everythings up even the things that bring bak the pics for u.

All i know is that theories aspect out maximum galaxies revolve round small black holes. i do not imagine there are images of something getting sucked into them, yet I have considered images of colliding galaxies.

I had a friend a colored guy and had decided he would be the black hole! Mathematically, of course! He took off his trouser, his short, bent down and pictured his ars. After that he sent that to the pentagon! and space aeronautics! and it was known has the BLACK HOLE! there are many black holes! and probably many more pictures of them! at Space and Aeronautics of Houston!

They can verify a black hole because it bends light, its gravity is that strong.

Black Hole is called that way because nothing can escape from it, even light so it is always dark.......
