Which specific wavelengths of light are largely blocked by the atmosphere?
Answer
Ultraviolet and infrared radiation
The Earth's atmosphere is highly selective and absorbs significant portions of the electromagnetic spectrum, particularly ultraviolet and infrared radiation, before they reach the surface. By placing a telescope in orbit, scientists gain access to these hidden wavelengths. Ultraviolet light is essential for studying hot, energetic stars and star formation processes, while infrared light is capable of penetrating dense clouds of interstellar dust that would otherwise obscure the centers of galaxies.
