Stellar Orbits Around Milky Way’s Central Black Hole (1995 - 2195)

This demo shows the observed and predicted orbits of thirteen stars that were used by astronomers at the Keck/UCLA Galactic Center Group to predict the position of a huge black hole at the center of the Milky Way. This data was provided by Andrea Ghez and Jessica Lu. The animation spans 200 years between 1995 and 2195. credit: UCLA/Keck Galactic Center Group source:
