Why is electromagnetic radiation important to astronomers?
Explanation: Electromagnetic Radiation is important in Astronomy because it helps us see the universe. It helps us see on earth to (Visible Light) lol. For example, X-Rays are released by Pulsars, but not visible light, so that’s how we know they exist.
What radiation do astronomers use?
Ultraviolet telescopes allow astronomers to study things such as the composition of the gas that exists between stars. Electromagnetic radiation with wavelengths between those of radio waves and visible light is called infrared light.
What is the most commonly used tool by astronomers to study stars?
telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy.
How does electromagnetic radiation help scientists study the universe?
Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.

How do astronomers use light to study stars and planets?
“You take the light from a star, planet or galaxy and pass it through a spectroscope, which is a bit like a prism letting you split the light into its component colours. “It lets you see the chemicals being absorbed or emitted by the light source.
What tools did the Mayans use to study astronomy?
They used observatories, shadow-casting devices, and observations of the horizon to trace the complex motions of the sun, the stars and planets in order to observe, calculate and record this information in their chronicles, or “codices”.
