Released August 5, 2009--The youngest of NASA's four Great Observatories is getting its second wind, and a relatively balmy one at that. Now that its helium coolant has run out, the Spitzer Space Telescope, launched in 2003, is entering the "warm" phase of its career.

At minus 406 degrees Fahrenheit (minus 243 Celsius), Spitzer is limited to two of its four infrared detector channels--but is still capable of capturing star-studded stunners like this July 21 image. Thanks to the remaining infrared eyes, which can pierce the haze that obscures visible-light pictures, both the dusty cloud DR22 (blueish) and the baby stars it swaddles are plain to see.
