Cosmic Shutterbug: Behind the James Webb Space Telescope.

This episode of "Behind the Webb" explores the multi-tasking capabilities of one of the cameras on the Webb Space Telescope, the Near-Infrared Spectrograph.

Newly designed technology known as "microshutters" - tens of thousands of tiny shutters that open and close to allow only the light from targeted objects to enter the instrument -- enables scientists to study the spectrum of more than one galaxy at a time. As many as 100 objects can be simultaneously observed.
