Webb Telescope: Why Infrared?

Dec. 16, 2021

The technology onboard NASA's James Webb Space Telescope, set to launch no earlier than Dec. 24, makes it the most powerful space telescope in history.

University of Arizona researchers led the design of the telescope's Near-Infrared Camera, and they also lead the science team for its Mid-Infrared Instrument.

These powerful infrared cameras can help astronomers peer into the universe like never before, to learn about infant galaxies, stellar nurseries, planets orbiting other stars and more.
