One that is fairly famous is Sagittarius A* - the supermassive black hole at the center of our Milky Way, about 26,000 light-years from here, and with a mass of about 4 million solar masses. For additional black holes, check the Wikipedia article "List of black holes".
black hole got it's name because when look at a black hole, you only see black. also if you drop an item in the black hole the item is gone because there is a hole in there. so that's how black hole get's its name
they are black and their bottomless!
It is likely that there is more than one black hole in our galaxy, but the one believed to be in the centre is called 'Sagittarius A*' (A Star). However, if it is not a black hole, then 'Sagittarius A*' refers to whatever it is found to be instead.
No black hole has ever been seen by anyone. The nature of a black hole actually prevents it from being seen. A black hole is the ultimate gravity well, and nothing that crosses the event horizon can escape. Not even light can get out. The only way a black hole can be "seen" is indirectly as it creates what is called gravity lensing. Light from objects "behnid" the black hole is "bent" around it, and it is this phenomenon that allows a black hole to be "seen" by observers.
The supermassive black hole at the center of our Milky Way galaxy may not have a formal name yet, but takes its identification from a powerful radio source "Sagittarius A*" (where the asterisk is part of the name). Because of the discovery of this energy source it's commonly believed a black hole must be located there, powering the emissions perhaps because of the black hole's accretion disk or relativistic jets.

The term "Black hole" first appeared in print in an article by Ann Ewing in "Black Holes in Space" published in 1964.
noone can go black hole as the name suggest it is a hole which is black so how any one can go ad com back...

As far as we know, most, if not all galaxies have a massive black hole at their centre.
Pick anyone and there will be black hole in it.
"Cygnus" is the latin word for "swan." It is the name given to a constellation in our skies. Within this constellation is a major source of x-rays; the source of which was eventually regarded as a black hole. This was the first object that most astronomers concluded was unambiguously a black hole, a conclusion reached about thirty years ago.
A black hole is an objects with such strong gravity that not even light can escape them. If observed up close a black hole would appear as a completely black sphere.
Yeah magic Johnson was said to have conquered the black hole. That's how he got 'magic' in his name. 2012 Olympics.
The term 'black hole' is particularly appropriate in its application to the astrophysical phenomenon of the same name due to the property of the escape velocity exceeding the speed of light. This means that no light or matter escapes a black hole.
