Astronomers searching for signals from alien civilisations have detected 15 powerful, repeated radio pulses coming from a dwarf galaxy 3 billion light years away from Earth.
The source of the mysterious signals, known as fast radio bursts, is unknown. Some have proposed they could be emanating from black holes or rotating neutron stars with extremely strong magnetic fields. A more speculative possibility is that they are beacons from extraterrestrial spacecraft.
The signals were picked up by the Breakthrough Listen project, a $100m (£77m) initiative to find signs of intelligent life in the universe set up by Professor Stephen Hawking and Russian internet billionaire Yuri Milner.
