Mysterious fast radio bursts release as much energy as the Sun pours out in a year – and newly published research has deepened the mystery around them.

Using a huge Chinese telescope, the team detected 1,863 bursts in 82 hours over 54 days from an active fast radio burst source called FRB 20201124A.

Fifteen years after the mysterious pulses from deep space were first discovered, the new observations have challenged received ideas about what causes the signals.

Scientists believe the signals come from collapsed stars – but some have suggested they might be evidence of extraterrestrial civilisations.
