The announcement of the discovery of two gas clouds that have formed in the first minutes after the Big Bang was published in Science; the clouds composition confirms theoretical predictions. The leading author of the study is the Italian Michele Fumagalli, from the University of California Santa Cruz, with whom we had a chat and to whom we asked for some clarifications.The discovery is the result of a clever observation technique and excellent performance of the spectrograph at the Hawaiian Observatory WM Keck.
