For only the second time ever, a series of Fast Radio Bursts (FRBs) have been discovered coming from a galaxy over 1 billion light years away. The extremely rare repetition was found by scientists in British Columbia. The bursts last less than half a second, but each one produces more energy than the sun does in one year.
Scientists remain stumped on what could be releasing the bursts. There are a vast array of occurrences that radio waves in space can indicate, such as star births, supermassive black holes, and dark matter.
