Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates . Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist. It is one of the most important principles that governs everything around us.
Read moreHow is the electromagnetic spectrum used in space?
Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas .
Read moreHow does NASA use electromagnetic waves?
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
Read moreWhat does NASA use the electromagnetic spectrum to study?
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.
Read moreDo astronomers use electromagnetic spectrum?
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.
