is there a vely large bLack hole in the center of our Galaxy?
-------------------------------------------------------
answers:
CarolOklaNola say: Yes, there is. It s called Sagittarius A*, or Sagittarius A prime, and it has 4.2 MILLION solar masses or more. It is a supermassive black hole with an event horizon with a large radius and diameter.
It is 23,000 to 30,000 (25,640) light years from us. You can see where it is in the southwest bottom corner of the Teapot asterism at about 3 to 5 am daylight time before sunrise.

MysteryGuy say: Yes. Every galaxy have millions of blackholes and one large one.
-
Tom S say: It is very massive, but not all that "large" in astronomical terms, similar to the size of a "Red Giant" star.
-
Jackolantern say: Scientists have said that every galaxy that they have investigated, has at least one black hole at it's center. And they have concluded that the development of a black hole is what started the stars, in that galaxy to form! No black hole, no galaxy!

rick29148 say: as a 'black hole' is STILL only a theory, your guess is as good as mine .........................
-
Luv D say: It's actually a coloured hole, black hole is a racist term
-
Ronald 7 say: Yes
It is Vely Supermassif one called Saggitarius AB
So Big they have given it two letters
It holds our whole galaxy together with its Mighty Gravity
For scale it must have the Mass of a Million of our Sun
And that is just the Singularity, or Singularities as it may well be
Imagine being in there !!

Jeffrey K say: Yes. Its about 30,000 light years from here.
-
quantumclaustrophobe say: It's a supermassive black hole - with the mass of millions of suns, but it's not all that large - the event horizon is thought to be about the size of Mercury's orbit.
-
megalomaniac say: Very likely, it's just hard to see (seeing as though even light can't escape it). Some astronomers think that there is likely a black hole at the center of all spiral galaxies. It fits with a lot of what we know but it is hard to prove exactly (and there is still plenty that we don't know about how the universe operates).

sally say: yeah its called Obamacare.

drake say: It is believed yes. In fact, a picture was just taken of it. There is a star named S2 which orbits the center of the galaxy with a highly elliptical orbit. This star is the closest star the center of our galaxy observed. The orbital period and radius of S2 has been measured. A shabby approximation of the mass of whatever object this star is orbiting can be calculated by letting newton's universal law of gravitation equate to the centripetal force acting on S2 and doing a little bit of algebra. Although the radius of S2's orbit would be greater than an event horizon, there is still nothing else known to science which can be compacted into such a tight space.

Emily say: Yeha if
-
cosmo say: Well, it's pretty large (around 4 Million solar masses), but not nearly as large as some other Black Holes.
-
sparrow say: Yeah. Scary isn't it? because it's only going grow larger and larger.
-
Lukas say: The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center (approx. 18 hrs, −29 deg), and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.

Gerald say: Yes its a space Bank deposit America deposits its debts there and unpaid tax's poof Abbracadabbra
-
poldi2 say: Yes, it is called Sagittarius A*.
