Summary

Description	Right after the Universe started with the Big Bang, the cosmos was dark. Only the first stars created millions of years later brought light. These first stars and their radiation drastically changed the Universe during what is known as the epoch of reionisation. This Hubblecasts talks about this important time, what Hubble has shown us so far, the open questions and what we can expect from future missions.
