Just like on Earth, dust is found everywhere in space, even in places we did not quite expect. In the last decade, surveys have unveiled an unexpected large amount of dust present in the most distant galaxies. This was surprising because these galaxies were the first to form after the Big Bang, a time when most metals were absent and, thus, the constituents of dust were not abundantly available. In this lecture, I will show how dust determined the evolution of the universe and unveil the mysterious dust sources at the earliest moments in the cosmos.
