What evidence is there to show this?The Milky Way, as seen from the Earth, is at its densest as it passes through Sagittarius. There is also a complex radio source Sagittarius A. Astronomers believe that one of its components, known as Sagittarius A*, is associated with a supermassive black hole at the center of the galaxy.The centre of the Milky Way lies in the constellation of Sagittarius. What evidence is there to show this?
Its the strongest region of the sky in radio, infrared, xrays, and sub-millimeter wavelengths.



The entire galaxy rotates around this point.



Coordinates of Galactic Center were first found by Harlow Shapley in his 1918 study of the distribution of globular clusters.The centre of the Milky Way lies in the constellation of Sagittarius. What evidence is there to show this?Hi. Sag A* has all evidence pointing to its being a very massive black hole. http://science.nasa.gov/headlines/y2000/鈥?/a>The centre of the Milky Way lies in the constellation of Sagittarius.
