Physicists Snap the First-Ever Picture of a Black Hole

In 2019, physicists took an absolutely unforgettable image of black hole M87, at the heart of the galaxy Virgo A, about 53 million light-years away.

According to the Live Science report, the first-ever close-up of the singularity, snapped by a network of telescopes around the world known as the Event Horizon Telescope, looks like a grainy, tiny spot surrounded by a fuzzy orange ring.

But that small, pixelated image is actually a black hole as big as the solar system and 6.5 billion times the mass of our sun.

The fiery orange glow surrounding its black heart demarcates its event horizon, the ring of matter that swirls around a black hole just before falling in. As it rubs against other matter at high speeds, it produces energy and glows to form an accretion disk — hence the orange ring.
