Behind the Webb: Star Catcher (Episode 23)

The Webb telescope will have four "cameras" at its disposal to explore the universe. The Near-Infrared Camera, or NIRCam, will focus its attention on distant galaxies and help us learn more about planets around other stars. But NIRCam is unique. Its vision will also be used to help align the telescope, a critical step in making the observatory function properly. Join Behind the Webb host Mary Estacion as she visits the Lockheed Martin facility in Palo Alto, Calif., to find out more about the making of NIRCam.
