Do astronomers use electromagnetic spectrum?

NASA utilizes the VHF band by airborne sensors to study the thickness of sea ice . NASA astronauts use UHF systems as backups for their voice communication systems. NASA also used these frequencies to remotely sense the Earth’s surface (e.g. soil moisture with the SMAP mission) and atmosphere.5 Eyl 2018

NASA’s scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the universe beyond . When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy.

Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space . Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
