MIRI, or Mid-Infrared Instrument, is an instrument on the James Webb Space Telescope.[1] MIRI is a camera and a spectrograph that observes mid to long infrared radiation from 5 to 28 microns.[1] It also has coronagraphs, especially for observing exoplanets.[2] Whereas most of the other instruments on Webb can see from the start of near infrared, or even as short as orange visible light, MIRI can see longer wavelength light.[1]
