Description:
This page, from the Andrea Ghez group at UCLA, provides a description of the group’s work in characterizing the center of the galaxy and the supermassive black hole believed to reside there. The site presents "Journey to the Center of the Galaxy," with progressively zoomed-in views and a series of images made of the central region in different wavelengths. A diagram of the orbits of the closest-in central stars is also included along with an animation showing their motion.
