How We Discovered the Milky Way's Black Hole

The video explores the discovery and study of Sagittarius A*, the supermassive black hole at the center of the Milky Way. Initially detected through radio waves by Karl Jansky in the 1930s, it wasn't until 1974 that astronomers confirmed its existence using radio interferometry. Despite early challenges in resolution, further research in the 2000s confirmed its mass and radius, solidifying its status as a black hole. Future observations aim to capture its image and test theories of gravity and space-time.
