Black Holes: Cosmic Mysteries Explained
Imagine a place in space where gravity is so strong, nothing, not even light, can escape!
That's a black hole.
They're formed when big stars die and collapse.
At the center is a point called a singularity.
Black holes can be found throughout the galaxy, including in the center of our Milky Way.
While the center of a black hole is incredibly cold, the area around it can emit radiation.
Scientists study black holes to understand the universe, even though they are invisible, they affect nearby objects.
The biggest known black hole is TON 618, which is billions of times bigger than our sun.
Black holes have gravity so strong that nothing can escape, not even light.
Gaia BH1 is the closest confirmed black hole to Earth, about 1,500 light-years away.
TON 618 is the biggest known black hole, with a mass about 66 billion times that of the Sun.
Sagittarius A* is the supermassive black hole at the center of the Milky Way galaxy.
Black holes' cores can be extremely cold, approaching absolute zero.
