Why is it necessary to detect radiation from space in more than just the visible range?

Detecting radiation from space beyond the visible range is essential because it provides crucial information about astronomical phenomena and cosmic events that are not observable through visible light alone. For instance, gamma rays can indicate high-energy processes like supernovae or black hole activity, while infrared radiation can reveal cooler celestial objects and dust clouds. This multi-wavelength approach allows for a more comprehensive understanding of the universe's composition, structure, and evolution. Additionally, it helps in studying phenomena like dark matter and cosmic background radiation, which are critical for understanding fundamental physics.
