NASA : NASA Engineers Conduct Low Light Test on New Technology for Webb Telescope


NASA Engineers Conduct Low Light Test on New Technology for Webb Telescope
NASA engineers inspect a new piece of technology developed for the James Webb Space Telescope, the micro shutter array, with a low light test at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Developed at Goddard to allow Webb's Near Infrared Spectrograph to obtain spectra of more than 100 objects in the universe simultaneously, the micro shutter array uses thousands of tiny shutters to capture spectra from selected objects of interest in space and block out light from all other sources.
The James Webb Space Telescope is a large space telescope, optimized for infrared wavelengths. It is scheduled for launch later in this decade. Webb will find the first galaxies that formed in the early universe, connecting the Big Bang to our own Milky Way galaxy. Webb will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own solar system.
