Okay, so technically they're called "fast radio bursts" but I prefer the idea of the sounds coming from aliens. Way more exciting that way. And who really knows for sure?

Some bright pulses of radio waves have been detected by astronomers. They say they're from a distant galaxy 1.5 billion light years away from earth. It's mind blowing that we can even detect something like that.

Astronomers aren't certain of the source, but they have considered the idea that they could be from intelligent aliens. I totally believe that's a possibility. How about you?
