The Mysterious Black Hole
How big is the largest known black hole?
A. 20 times the size of the Milky Way galaxy
B. 40 times the size of the Milky Way galaxy
C. 60 times the size of the Milky Way galaxy
Answer:
A. 20 times the size of the Milky Way galaxy
The size of the largest known black hole is about 20 times the size of the Milky Way galaxy. This massive black hole was discovered in 2011 by astronomers and is located in the galaxy NGC 4889. It has a mass equivalent to 21 billion suns and is one of the most massive black holes ever observed.
Black holes are mysterious objects in space that have such strong gravitational pulls that nothing, not even light, can escape from them. They are formed when massive stars collapse in on themselves at the end of their life cycles. The massive black hole in NGC 4889 is an example of the extreme sizes that black holes can reach.
It is truly mind-boggling to think about the immense scale of these cosmic giants and the powerful forces at play in the universe.
