Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

The origin of the millisecond-long flashes of radio waves is unknown. Most scientists believe they are generated by powerful astrophysical phenomena such as black holes or superdense neutron stars.

Aliens could already be broadcasting clear signals across the cosmos while humans remain 'utterly blind' to them, according to astronomer Prof. Jon Willis, who argues that our current search ...

Seventy-five years ago, a group of Dutch astronomers made a remarkable discovery. Using emerging radio techniques refined during and after the Second World War, the astronomers detected a powerful ...

Scientists around the world have spent decades pointing radio telescopes at the sky, hoping to catch that one signal proving we’re not alone in the universe. But now researchers at SETI are asking: ...

Scientists have long predicted that as long as there are countless stars like the Sun in the universe, intelligent life should exist on other planets, just as it does on Earth. However, for decades, ...
