in 3 to 5 sentences explain how astronomers use the electromagnetic spectrum when measuring light emitted from planetary objects. make sure your response includes an example.

Answer 1

Astronomers utilize the electromagnetic spectrum to analyze the light emitted from planetary objects, helping them understand various properties such as composition, temperature, and movement. Different wavelengths of light, including infrared, visible, and ultraviolet, reveal unique information; for instance, infrared observations can detect heat emitted by planets and their atmospheres. An example is the use of the Hubble Space Telescope, which captures ultraviolet and visible light from distant exoplanets to study their atmospheric composition, allowing scientists to identify the presence of molecules such as water vapor or carbon dioxide. By interpreting this data across the electromagnetic spectrum, astronomers can construct a more comprehensive picture of celestial bodies and their potential for supporting life.
