mission coverage

The JWST Mid-Infrared Instrument (MIRI) provides imaging and spectroscopic observing modes in mid-infrared wavelengths. These wavelengths can be utilized for studies including (but not limited to): direct imaging of young warm exoplanets and spectroscopy of their atmospheres; identification and characterization of the first galaxies at redshifts > 7; and analysis of warm dust and molecular gas in young stars and proto-planetary disks.
