An x-ray telescope is a special tool that helps scientists see things in space that are too far away or too small for the human eye to see. It works by using a special lens that can gather x-rays, which are a type of light that can pass through things like gas and dust that might be blocking our view of space.
Just like a regular telescope, an x-ray telescope has a tube that helps focus and collect the x-rays. Then, the x-rays are sent to special cameras or detectors that can turn them into pictures that scientists can study.
Because x-rays can tell us a lot about the temperature and other physical properties of things in space, an x-ray telescope is really useful for studying things like black holes and other objects that emit x-rays. It can also help us learn more about how galaxies and other large structures form and evolve over time.
In short, an x-ray telescope is a powerful tool that helps us see the unseen in space!
