The following information will inform your students where pictures and information scientists use to study the stars comes from. Scientists want to explore stars and the solar system in order to better understand our universe. They gather and record information about these faraway places through remote sensing. Although these remote sensing instruments never touch or even get close to the stars, they observe and record images, which allow scientists to learn more about them. These are some of the remote sensing equipment they use to gather information.
Optical telescopes are extremely powerful telescopes that magnify images in space.
The lens can be over 200 inches wide. Radio telescopes work by picking up sounds. They collect faint signals called radio waves from objects in space. This information is converted into images by computers. Satellites like the Hubbell Space Telescope have powerful telescopes mounted on them.
