Wallpaper of the Week
My wallpaper this week is
from the Cal Tech/NASA/Jet Propulsion Lab Spitzer Space
Telescope.
Launched Aug. 25 from Cape Canaveral, Fla., the Spitzer Space Telescope is the fourth of NASA's Great Observatories, a program designed to paint a more comprehensive picture of the cosmos using different wavelengths of light.
While the other Great Observatories have probed the universe with visible light (Hubble Space Telescope), gamma rays (Compton Gamma Ray Observatory) and X-rays (Chandra X-ray Observatory), the Spitzer Space Telescope observes the cosmos in the infrared.
