DR22, Space Cloud
One of the first to be taken during Spitzer's warm mission, a new phase that began after the telescope, which operated for more than five-and-a-half years, ran out of liquid coolant. The pictures were snapped with the two infrared channels that still work at Spitzer's still-quite-chilly temperature of 30 Kelvin (about minus 406 degrees Fahrenheit). The two infrared channels are part of Spitzer's infrared array camera: light is blue and light is orange. Shows a cloud, known as DR22, bursting with new stars in the Cygnus region of the sky. Spitzer's infrared eyes can see dust, and see through dust, giving it a unique view into star-forming nests. The blue areas are dusty clouds, and the orange is mainly hot gas.
