MIRI, or the Mid-Infrared Instrument, is one of the four main scientific instruments aboard the James Webb Space Telescope (JWST). It is designed to observe the universe in the mid-infrared part of the electromagnetic spectrum. MIRI’s capabilities allow it to study phenomena such as newly forming stars within dust clouds, the formation of planets around other stars, and the physical and chemical properties of galaxies in the early universe. Equipped with both a camera and a spectrograph, MIRI provides unique data by capturing detailed images and spectra. Its observations are vital for understanding celestial objects that are otherwise obscured in visible light due to dust.
