Stars circling the supermassive black hole in the center of our galaxy
Max-Planck Institute for Extraterrestrial Physics (MPE)
"An international team of astronomers, lead by researchers at the Max-Planck Institute for Extraterrestrial Physics (MPE), has directly observed an otherwise normal star orbiting the supermassive black hole at the center of the Milky Way Galaxy."
"Andrea Ghez et al of the UCLA Astronomy Department's Galactic Center Group published a paper in Nature in 2000 where they observe orbits of a dozen individual stars near the center of our galaxy. They used these observations to predict the position of a supermassive black hole there. This movie shows these observations, with their extrapolated orbits. The side of the initial box is about 0.8 parsecs (15 trillion miles), while the cross in the center is the position of the black hole."
