Black holes are fascinating objects in the universe that are incredibly dangerous. They are formed when a star collapses in on itself, creating a gravitational pull so intense that not even light can escape. Black holes can be very large, with the largest one known being about the size of our solar system.

A black hole is a region of spacetime with a gravitational pull so strong that nothing, not even light, can escape from it. Black holes are usually formed when a star dies and collapses in on itself. The first black hole was discovered in 1971. The largest black hole discovered to date is about 60 times the mass of our sun. Black holes can grow by absorbing other objects. Some black holes emit jets of particles at high speeds.
Black holes are amazing and fascinating objects in the universe. They are actually quite common, and come in three different types. Black holes can vary greatly in size, and can spin at extremely high speeds. They can also emit X-rays and gamma rays.
