Question

Layla Anderson · Accepted Answer

Electro magnetic radiation comes from stars and Galaxies in different wave lengths from Gama rays to radio waves.

Astronomers use telescopes of all kind.They include telescopes that work on visible light, infra red, UV rays and Radio waves on surface of earth
Space telescopes are used to study universe through Gama rays, X rays and other parts of UV, infra red as these waves are booked by Earth's atmosphere.
Examples Hubble space telescope.Chandra x RAY TELESCOPE.

undefined Electromagnetic radiation is used to provide information about the universe through various methods such as spectroscopy, imaging, and radio astronomy. Spectroscopy analyzes the spectrum of light emitted or absorbed by celestial objects, revealing their chemical composition and physical properties. Imaging techniques capture images of celestial objects across different wavelengths, allowing astronomers to study their structure and morphology. Radio astronomy uses radio waves to observe cosmic phenomena such as pulsars, galaxies, and the cosmic microwave background radiation, providing insights into the universe's large-scale structure and evolution.
