📖 Read the story
Black holes are very strange and heavy objects in space. They have very strong gravity. Gravity is a force that pulls everything towards the center. There is a special line around a black hole. Scientists call it the ‘event horizon.’ If something crosses this line, it can never come back. Even light cannot escape from a black hole! In 2019, scientists took the first photo of a black hole. The picture shows a dark circle with a bright ring of light. The light comes from very hot gas. The center is black because the light is trapped inside. Scientists use big telescopes to study these mysteries. They want to learn more about our universe and its secrets. Space is very big and exciting. Black holes are difficult to see because they are dark, but they are very important. Would you like to be a scientist and study the stars one day?
