Secrets from the beginning of the Universe are being whispered throughout space — and now, we know where to listen.
A team of astronomers plans to send a mini spacecraft to the far side of the moon in order to listen for radio signals from the cosmic Dark Ages, which is the least understood epoch of the Universe’s history. They presented their out-of-this-world plan at the Royal Astronomical Society’s National Astronomy Meeting 2025.
Why do we need to go to the dark side of the moon to hear these whispers? Earth is much too loud, with atmospheric and electronic interference drowning out these cosmic radio signals.
“It’s like trying to hear that whisper while a loud concert is playing next door. This makes it really hard to pick up on those faint signals from billions of years ago,” said Eloy de lera Acedo, head of Cavendish Radio Astronomy and Cosmology ...
