World’s largest radio telescope begins study of cosmic dawn
One of the 21st Century's grand scientific undertakings has begun its quest to view the 'Cosmic Dawn'.
The Atacama large milllimetre/submillimetre array (Alma) in Chile is the largest, most complex telescope ever built.
Alma's purpose is to study processes occurring a few hundred million years after the formation of the Universe when the first stars began to shine.
Its work should help explain why the cosmos looks the way it does today.
