Text, MYTH versus REALITY 


Myth side 


Text, Galaxies shine only in visible light. 


Reality side 


Text, Galaxies emit different types of radiation. Most types of light are invisible to us. Detecting other types of radiation, such as infrared light, X-rays, and ultraviolet light, provides more information and allows us to better understand what is happening inside galaxies.
