Technology
Astronomers are getting closer to solving one of the universe's biggest mysteries.Fast radio bursts (FRBs) are transient radio pulses that emit more energy in a single millisecond than the sun does all day.As many as 10,000 of them are thought to occur every day but so far astronomers have only spotted dozens and have struggled to pin down their origin.Fast radio bursts are extremely powerful but they are also very short, lasting only milliseconds.Making a researcher's task even more difficult, many of them only happen once.One, however, has been observed to repeat itself sporadically, allowing researchers to examine it more closely.FRB 121102 could have come from an extreme environment - "among the most highly-magnetised regions of space ever observed", researchers say in a report contain...
