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 ...

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.
