Event Horizon. The Biggest Telescope in the World
It was 1974 when astronomers Bruce Balick
URLand Robert L. Brown reported the detection
of very intense radio emission coming from
the center of our galaxy in the direction of the
Sagittarius constellation. Its morphology and
brightness led its discoverers to suggest a similarity
of that radio source—later named Sagittarius A*—
to the energetic cores of distant galaxies where
the fall of matter into a supermassive black hole
produces intense electromagnetic radiation and
particle jets.
