Why is the center of the Milky Way bright if it is a black hole?

The black hole at the center is a giant collection of mass. Even though the hole itself keeps light from escaping, the mass has still attracted stars around it. The orb gives no light, but the stars pulled to it have light of their own and it's very dense at the center.
