Mondo Knows Facts
The Spitzer Space Telescope peered through interstellar dust clouds
Thermal infrared detectors imaged cold dust planet birth and faint stars
Launched in 2003 as one of NASA's Great Observatories, the Spitzer Space Telescope observed the universe in thermal infrared light. By capturing longer wavelengths capable of penetrating thick interstellar dust clouds, Spitzer revealed planet-forming protoplanetary discs, cool brown dwarfs and distant infant galaxies.
