NASA's Spitzer Space Telescope is starting a second career and taking its first shots of the cosmos since warming up. The infrared telescope ran out of coolant May 15, 2009, more than five-and-a-half-years after launch. It has since warmed to a still-frosty 30 degrees Kelvin (about minus 406 degrees Fahrenheit). New images taken with two of Spitzer's infrared detector channels -- two that work at the new, warmer temperature -- demonstrate the observatory remains a powerful tool for probing.
