An FRB or fast radio burst occurred on April 18th of last year, and, based on the collected data, scientists were able to determine that it came from an elliptical galaxy around 6 billion light years away.

The cosmic activity known as fast radio bursts, or FRBs, have remained a mystery to astronomers, but a recent study by an international team of researchers provides some startling insights into the phenomenon. 
FRBs are flashes of radio signals that are typically over in milliseconds; before this research, only 16 had been identified. 
Because these events are fast, rare, and usually discovered from months to years after they happen, a team created an alert
