Apr 11, 2022 · The “dark rift,” which runs lengthwise down a long part of the Milky Way in our sky and appears to split it in two, is produced by a collection of such obscuring clouds. While dust clouds are too cold to radiate a measurable amount of energy in the visible part of the spectrum, they glow brightly in the infrared (Figure \(\PageIndex{3}\)).

Clouds of dust that range from hundreds to tens of degrees above absolute zero appear as black soot in visible light, but glow brightly at infrared wavelengths out to several hundred microns. So, to study the cool cosmos, infrared light is our window into the heat of the coolest things around.

May 3, 2023 · The center of our Milky Way galaxy is hidden from the prying eyes of optical telescopes by clouds of obscuring dust and gas. But in this stunning vista, NASA's Spitzer Space Telescope's infrared cameras penetrate much of the dust, revealing the stars of the crowded galactic center region.

What is infrared light?
What is infrared light? The electromagnetic spectrum spans a wide range of wavelengths from very short wavelength and highly energetic gamma rays to very long wavelength and low-energy radio waves. The visible part of the spectrum is only a small portion. Infrared light is the same as the light that we can see except that the wavelength is ...
