One example of using electromagnetic radiation other than visible light is the observation of distant galaxies through radio waves. Radio telescopes can detect emissions from cold hydrogen gas in galaxies and pinpoint structures and dynamics that are not visible in the optical spectrum, allowing astronomers to study the formation and evolution of galaxies. Additionally, infrared radiation can reveal heat emitted by celestial objects, providing insights into cooler stars, nebulae, and the distribution of dust in space that would be invisible in visible light.
In 2-3 sentences, explain an example in which electromagnetic radiation other than visible light can be used to show us more about an object than visible light alone.
Hint: Consider some of the examples that were provided within this unit on The Universe that emit other
