*BRIEFING RECORDING NOW AVAILABLE* Australian researchers using a CSIRO telescope in Western Australia have detected 20 mysterious radio signals known as 'fast radio bursts' in a year - almost double the number of unique signals detected worldwide since they were discovered in 2007. The team also found the closest and brightest fast radio bursts ever detected. Scientists don’t know what causes these mysterious radio waves - could they be supernovas? Black holes? Or something else? One thing scientists do know is that fast radio bursts are coming from the other side of the universe. They also must involve incredible energy, equivalent to the amount released by the Sun in 80 years. Their findings will be published in Nature this week. Join this briefing to hear from the researchers who detected these enigmatic radio waves, and what they know so far.
