The Mid-Infrared Instrument (MIRI) is a scientific tool designed for use in space telescopes, particularly in the James Webb Space Telescope. It operates in the mid-infrared wavelength range, allowing astronomers to observe celestial objects that emit heat rather than visible light. This capability is crucial for studying cooler objects in the universe, such as distant galaxies, star-forming regions, and exoplanets. MIRI combines both imaging and spectroscopic functions, enabling detailed analysis of the composition and physical properties of astronomical targets. By capturing data in the mid-infrared spectrum, MIRI helps scientists gain insights into the formation of stars and planets, as well as the evolution of galaxies over time.
