A unique instrument for the biggest telescope

The proposed MOSAIC multi-object spectrograph will be the workhorse instrument for the future Extremely Large Telescope (ELT), the biggest visible/infrared telescope in the world. It will be the world-leading multi-object spectrograph well into the 2020s, contributing to most fields of contemporary astronomy. Scientists from across the world are meeting in Toledo to explore the unprecedented capabilities of MOSAIC in tracking the earliest ‘first-light’ structures in the Universe, and to refine proposals for observations that will uniquely trace the amounts of dark and invisible matter in the deep Universe.
