The Maunakea Spectroscopic Explorer (MSE) will fill what is arguably the “missing link” in the international suite of astronomical facilities in the 2020s, namely: fully dedicated, 10m-class, wide-field spectroscopy of thousands of objects per hour at low, intermediate and high spectral resolutions. This facility will be provided by upgrading the existing CFHT and expanding the partnership.

MSE seeks to tackle basic science questions ranging from the origin of stars and stellar systems, Galaxy archaeology at early times, galaxy evolution across cosmic time, to cosmology and the nature of dark matter and dark energy. MSE will be a primary follow-up facility for many key future photometric and astrometric surveys, as well as a major component in the study of the multi-wavelength Universe.

An international Science Team leads the ongoing development of the science case, science requirements, and science reference observations. On these pages you can find current information relating to all aspects of the scientific development of the project.
