JPL Celebrates the Legacy of the Spitzer Space Telescope

In this artist's rendering of NASA's Spitzer Space Telescope in space, the background is shown in infrared light. Credit: NASA/JPL-Caltech NASA is celebrating the legacy of one of its Great Observatories, the Spitzer Space Telescope, which has studied the universe in infrared light for more than 16 years. The Spitzer mission will come to a close on Jan. 30. Launched in 2003, Spitzer revealed previously hidden features of known cosmic objects and led to discoveries and insights spanning from our own solar system to nearly the edge of the universe. “Spitzer taught us how important infrared light is to understanding…
