Mysterious Radio Signals Are Coming From A Galaxy Over A Billion Light-Years Away

Far out.

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.

However, these conditions are less likely to emit a consistent repetition of radio waves.

Astrophysicist Ingrid Stairs elaborated on this for The Independent:

“Until now, there was only one known repeating FRB. Knowing that there is another suggests that there could be more out there. And with more repeaters and more sources available for study, we may be able to understand these cosmic puzzles—where they’re from and what causes them.”

Twitter users have a theory, and it’s one you might have expected.

If the signals are coming from intelligent extraterrestrial life, humans in the United States are scared of one thing in particular.
