Research telescopes include scientific instruments that record light precisely. The extreme sensitivity and precision of @NASAWebb’s four instruments support its unprecedented scientific power: bit.ly/3fIQm35 Credit: NASA. #AAS238 (1/7) 
Each of Webb’s four instruments is like a Swiss army knife of specialized components, with multiple ways of observing. All four can be used for investigations of the wide variety of objects that make up the universe, including planets, stars, nebulae, and galaxies. #AAS238 (2/7)
Webb’s instruments are housed in the Integrated Science Instrument Module (ISIM), which is situated behind the primary mirror on the cold side of the telescope where it is protected by the sunshield. Credit: NASA and STScI. #AAS238 (3/7)
There are two broad groups of observation modes on Webb: imaging and spectroscopy. Imaging is equivalent to digital photography and is used to detect objects in a large field of view. #AAS238 (4/7)
During a spectroscopic observation, light from space is directed through a spectrograph, which spreads the light out into its component wavelengths. Webb has six spectroscopy modes which all involve filters and detectors as well as spectrographs. Credit: STScI. #AAS238 (5/7)
What makes each of Webb’s instruments unique is its specific combination of components, observing modes, wavelength range, field of view, and resolution. Instrument details: bit.ly/3fIQm35 #AAS238 (6/7)
The Space Telescope Science Institute (@stsci) offers a variety of experts working directly with the telescope and the mission who are prepared to communicate in an understandable, public-friendly manner. Connect with our news team: bit.ly/3ce0n61 #AAS238 (7/7)
