This #NationalCameraDay, we're spotlighting the different cameras that will be helping Webb and @NASARoman uncover mysteries of our universe.
So how do Webb's cameras compare to cameras in our daily lives? Thread

Webb is a heat seeker that will detect invisible infrared light, unlike our phone cameras, which photograph visible light. The cameras on Webb's NIRCam and NIRISS instruments will both see in the near-infrared range, while its MIRI instrument will take images in mid-infrared.pic.twitter.com/pvTMOx6t6E
You may have seen far-infrared cameras at your local museum. These cameras tend to be low-resolution and usually produce grainy images compared to Webb's near-infrared & mid-infrared cameras. For reference, Webb's NIRCam features detectors that each have about 4 million pixels!pic.twitter.com/ssF3hx7UFY
Because we can't see in infrared, Webb's images must be "translated" with color to differentiate between wavelengths of light. In this Spitzer infrared image, blue represents light at a wavelength of 3.6 microns. Green represents 8-micron light, and red is 24-micron light.pic.twitter.com/2uBaVFEOlF

this is absolutely insane! can't wait for the launch!
This is ridiculously amazing and cool!
