The James Webb Space Telescope, launched on Christmas day 2021, has revolutionized many areas of astronomy, from exoplanets to the high-redshift universe. The unprecedented sensitivity at infrared wavelengths allows JWST to detect and study galaxies only a few 100 Myrs after the Bing Bang as well as observe highly dusty galaxies in their rest frame optical/near-infrared light.

In this talk I will present the results of the MIRI-GTO program focussed on the high redshift universe. i will describe the program in general and focus specifically on the result of the deep MIRI-MRS spectroscopic observations, allowing us to probe deep in to the dusty hearts of dusty star forming galaxies and perform a spatially resolved analysis of the ISM of galaxies at redshifts 9-10.
