Have you ever wondered how we get those amazing pictures of space from the James Webb Space Telescope? It’s pretty cool! The telescope uses something called a radio transmitter to send information back to Earth.
Radio waves are a type of electromagnetic wave. You might know other types of electromagnetic waves, like the light we see with our eyes or the microwaves that heat up our food. All these waves move energy from one place to another. The great thing about electromagnetic waves is that they can travel through space, which is why space telescopes and astronauts use them to communicate.
When the James Webb Space Telescope takes a picture of space, it uses its radio transmitter to send radio waves back to Earth. These waves carry information by making tiny changes in the waves to represent each part of the picture.
Once the radio waves reach Earth, computers work their magic. They turn the information from the waves into colors on a screen, creating the beautiful space images we see.
So, next time you think about radios, remember they’re not just for music. They also help us explore and see the wonders of space!
