A black hole is in some galaxies. A galaxy is a big group of stars. Black holes are very heavy objects. They have a strong pull. Nothing can escape a black hole. Even light cannot get out. This makes black holes very dark. We cannot see them with our eyes.
A new telescope is in space. It is called James Webb. This telescope looked at the sky. It found black holes that are very big. These black holes are bigger than scientists expected. This was a big surprise. Now scientists have new questions.
Old ideas about black holes may be wrong. Scientists need to learn more. They want to know how these black holes grew so big. This helps us understand the sky better. There is still much to learn about space.
