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:
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.
