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 for such an infrared mission is that infrared 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 in 2013 for a new mission, NEOWISE (for Near Earth Object WISE), specifically to search for near-Earth objects, and is still active as of 2020.
