The Question

(Submitted December 15, 1996)

I am 5 years old. How do X-rays work?

The Answer

Here at NASA we catch X-rays from far away things. From these X-rays we can learn about those far away things -- like stars and galaxies.

When you go to the doctor an get an X-ray, it is similar. The doctor shoots X-rays in one side of you, and then film catches the X-rays on the other. This makes a picture of your inside, showing your bones really well.

Thank you for asking.
