Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a space telescope mission proposal by the European Space Agency that would study gamma-ray bursts and X-rays for investigating the early universe.[1][3] If developed, the mission would investigate star formation rates and metallicity evolution, as well as studying the sources and physics of reionization.
