MAROON-X is a new instrument recently constructed at the University of Chicago which is expected to have the capability to detect Earth-size planets in the habitable zones of mid- to late-M dwarfs using the radial velocity method. At its core, the instrument is a high-resolution (R~80,000) optical (500-920nm), bench-mounted, fiber-fed echelle spectrograph designed to deliver 1 m/s radial velocity precision for M dwarfs down to and beyond V = 16.
