An infrared telescope is like a giant eye that can see things that are invisible to our normal eyes. Just like how some animals can see things that we can't, like bats can see in the dark, an infrared telescope can see things that are too faint or don't give off enough light for us to see.
Infrared light is a type of light that is too long for our eyes to see, but it is still there. It comes from anything that gives off heat, like a warm person, a fire, or even the Earth itself. The infrared telescope can detect this light and make pictures of it.
This helps scientists learn more about things like stars, galaxies, and even black holes. These things give off infrared light that the telescope can capture, so scientists can learn more about them and how they work. It's like having superpowers to see things that are invisible to us!
