At the center of our Milky Way Galaxy lies supermassive black hole – known as Sagittarius A*. Join us on a virtual journey, 150 trillion miles from Earth, to explore the center of our home galaxy in 360-degrees. Created using data from our Chandra X-ray Observatory and other telescopes, this project allows you to explore the fascinating environment of volatile giant stars and powerful gravity around this monster black hole.
