In the image, the gas silhouettes the black hole itself. Light can't escape a black hole but hot plasma swirling around it emits short radio waves that radio telescopes can pick up.The false color orange-yellow in the image is the silhouette of the black hole created by matter teetering on its edge, or event horizon.Most galaxies are thought to have a supermassive black hole at their center.Why it matters: The "historic breakthrough" offers an unprecedented look at the extreme object driving the evolution of our galaxy.ĭriving the news: Astronomers imaged Sagittarius A* (Sgr A*) using the Event Horizon Telescope (EHT), scientists announced at a press conference Thursday. Astronomers have captured the first image of the black hole at the center of the Milky Way. ![]()
