"Astronomers have captured the first image of a black hole, heralding a revolution in our understanding of the universe’s most enigmatic objects. The picture shows a halo of dust and gas, tracing the outline of a colossal black hole, at the heart of the Messier 87 galaxy, 55m light years from Earth." - The Guardian
A great day for science and scientists around the world. As one of the speakers said, today one of our most incredible mathematical concepts went from an equation on the blackboard to a real image for everyone to see. Congratulations to all of those incredibly smart and dedicated people for showing us this wonder.
