How does space research use the electromagnetic spectrum?
1 answer
Space research uses the electromagnetic spectrum to study the universe. Telescopes use different parts of the spectrum to observe different objects in space, such as stars, galaxies, and planets. Radio telescopes use the radio portion of the spectrum to detect radio waves emitted by stars and galaxies. Infrared telescopes use the infrared portion of the spectrum to detect heat radiation from stars and galaxies. Ultraviolet telescopes use the ultraviolet portion of the spectrum to detect ultraviolet radiation from stars and galaxies. X-ray telescopes use the X-ray portion of the spectrum to detect X-rays from stars and galaxies. Gamma-ray telescopes use the gamma-ray portion of the spectrum to detect gamma-rays from stars and galaxies.
