Final answer:
Observing light from other wavelengths that don't penetrate our atmosphere can be done by using telescopes placed in space. Earth's atmosphere blocks most radiation at wavelengths shorter than visible light, so direct observations of other wavelengths such as ultraviolet, X-ray, and gamma ray can only be made from space. Placing telescopes in space allows astronomers to obtain clearer images and gather information from various bands of the electromagnetic spectrum.
Step-by-step explanation:
Earth's atmosphere blocks most radiation at wavelengths shorter than visible light, so direct observations of other wavelengths such as ultraviolet, X-ray, and gamma ray can only be made from space. Observing from space allows astronomers to overcome the blurring effect of Earth's atmosphere and obtain clearer images. Telescopes placed in space can gather information from various bands of the electromagnetic spectrum, providing a broader understanding of astronomical phenomena. However, placing telescopes in space is expensive and repairs can be challenging, so astronomers also build telescopes for use on the ground.
