NIRSpec, however, will deliver an unprecedented amount of information about not only the galaxies,As a spectrograph, NIRSpec doesn't take images. It splits the incoming light into individual components of the light spectrum. This spectrum, like a fingerprint, reflects the light-absorbing properties of the imaged objects and thus their chemical composition.
"The slit allows you to get as sensitive as you can," Bunker said."But the limitation is doing just one object at a time. It's very ineffective, particularly if you look at some of the deep fields where you have very high densities of potentially interesting objects." The first spectrograph of its kind flown in space, NIRSpec features a range of innovative technologies. The microshutter array itself, developed by engineers at NASA's Goddard Space Flight Center, is arranged in four rectangular sections, each having 365 by 171 microshutters.
The Near Infrared Spectrograph on the James Webb Space Telescope is the most powerful instrument of its kind ever flown in space.The vast quantities of stars, galaxies, clusters, planets and other bodies NIRSpec is going to look at will enable scientists to start answering the big questions not about individual stars and galaxies, but the entire universe.

Giant Space Telescopes Could Be Made Out of Liquid - Universe TodayThe Hubble space telescope has a primary mirror of 2.4 meters. The Nancy Grace Roman telescope has one at 2.4 meters and the James Webb Space Telescope has a whopping 6.5 meter primary mirror. These are all fine and well to get the job done that they were designed for, but what if… we could … Continue reading 'Giant Space Telescopes Could Be Made Out of Liquid'
