Chinese astronomers aim to peer for the first time into the cosmic “dark ages,” an unexplored era about 200 million years after the Big Bang, by using the Moon as a shield to block out noisy radio signals caused by human activity on Earth, reports the South China Morning Post.

The Discovering the Sky at the Longest Wavelength (DSL) mission envisions sending a fleet of satellites to the Moon that could capture ultralong radio waves made by hydrogen atoms in the darkness before cosmic dawn, when the first stars were born bursting with radiant light.
