Astronomers map the hidden Universe

Astronomers from Cardiff University are involved in a race against time to uncover the hidden secrets of the Universe. The team, from the Department of Physics and Astronomy, are completing the very first survey for cosmic hydrogen – the primeval gas which emerged from the Big Bang to form all the stars and galaxies we can see today.
