What is a black hole?
Mystery Science・7 minutes read
A black hole is an object with immense gravity, stronger than any other celestial body, making it impossible for light to escape, leading to its name. Scientists discovered black holes in the universe by observing light absorbed by black spots, and the first-ever image was captured by a team of 200 astronomers using telescopes acting as one Earth-sized telescope, opening up possibilities for more discoveries in space.
Insights
- Black holes are incredibly dense objects with gravitational pull so strong that not even light can escape, leading to their name due to the absorption of light and matter.
- The collaborative effort of 200 astronomers using a network of telescopes allowed for the first-ever image of a black hole to be captured, showcasing the potential for further discoveries in celestial phenomena beyond black holes.
