M87 Black Hole Image

Definition

The M87 black hole image is the first-ever photograph of a black hole, captured by the Event Horizon Telescope (EHT) in April 2019. This groundbreaking image showed the shadow of the supermassive black hole at the center of the galaxy M87, providing direct visual evidence of black holes and confirming theoretical predictions about their existence.

5 Must Know Facts For Your Next Test

1. The M87 black hole is located about 53 million light-years away from Earth in the Virgo galaxy cluster.
2. The image was produced by combining data from multiple radio observatories around the world to form a planet-sized virtual telescope.
3. The shadow observed in the M87 image corresponds to a region where light cannot escape due to the intense gravitational pull of the black hole.
4. The success of capturing this image has revolutionized astrophysics and provided new insights into how black holes behave and interact with their surroundings.
5. The EHT collaboration involved hundreds of researchers worldwide, highlighting the power of international cooperation in modern scientific endeavors.
