<P> Sagittarius A * ( pronounced `` Sagittarius A-star '' , standard abbreviation Sgr A * ) is a bright and very compact astronomical radio source at the center of the Milky Way , near the border of the constellations Sagittarius and Scorpius . It is part of a larger astronomical feature known as Sagittarius A. Sagittarius A * is thought to be the location of a supermassive black hole , like those that are now generally accepted to be at the centers of most spiral and elliptical galaxies . Observations of the star S2 in orbit around Sagittarius A * have been used to show the presence of , and produce data about , the Milky Way 's central supermassive black hole , and have led to the conclusion that Sagittarius A * is the site of that black hole . </P>
