Explore outer space through interactive augmented reality experiences! A supermassive black hole exists at the center of the Milky Way galaxy--how did astronomers discover it was there? Scientists have known about black holes for many years, but these objects are difficult to study because nothing can escape their gravity, not even light. But modern technology is helping us learn more. Scientists can use gravitational waves created by black holes and other huge objects in space to listen to the universe. Astronomers even captured the first image of a black hole's event horizon. Join scientists as they attempt to unravel the secrets behind the universe's most mysterious objects.
