Wide-Field Infrared Survey Explorer

(infrared space telescope aimed at an all-sky survey)

Wide-Field Infrared Survey Explorer (WISE) is a satellite launched in December 2009, aimed at a 1 year mission. The aim was to image the whole sky in Infrared, aiming to observe stellar nurseries and to detect Asteroids. A reason to use infrared is that it penetrates Dust.

It Surveyed four Wavelengths in the infrared:

WISE LabelBand
w13.4 micrometers
w24.5 micrometers
w312 micrometers
w422 micrometers

Differences in these, e.g., w1-w2 and w2-w3 are useful in identifying obscured Active Galactic Nuclei.

The spacecraft was put in hibernation while still operational when the intended mission was completed. It was revived for a new mission, NEOWISE (for Near Earth Object WISE), specifically to search for Near-Earth Objects.
