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: 3.6-micron light is blue and 4.5-micron light is orange.
But this star, called HD 34989 (among other alphanumeric designations) is special. For one thing, it's massive, probably 10 times the mass of our Sun. It's also incredibly luminous, shining 15,000 times brighter than the Sun. Put that in the center of our solar system, and the global warming we're experiencing now would seem like the deep freeze. Happily, it's over a thousand light years away.
