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.
