* Cameras: Just like the camera on your phone, cameras on spacecraft are used to capture images of space. These cameras can be very sophisticated, and can take pictures in a variety of different wavelengths of light, including visible light, infrared light, and ultraviolet light.
* Telescopes: Telescopes are used to magnify images of distant objects, such as planets, stars, and galaxies. They can also be used to take pictures of objects that are too faint to be seen with the naked eye.
* Radio Telescopes: Radio telescopes use radio waves to collect data about objects in space. This data can be used to create images of these objects, as well as to study their chemical composition and other properties.
* Spectrometers: Spectrometers measure the amount of light that is emitted or absorbed by an object. This data can be used to determine the object's composition, temperature, and other properties.
* Photometers: Photometers measure the brightness of an object. This data can be used to study the object's surface features, as well as to track its movements.
These are just a few of the many different instruments that are used to send pictures from outer space to Earth. These instruments allow scientists to study the universe in ways that would not be possible otherwise.
