While looking for signs of intelligent life in the universe, astronomers have detected 15 fast radio bursts from a distant galaxy. This particular fast radio burst (FRB), called FRB 121102, is of particular interest as it is the only known one to be repeating, something that astronomers can't yet explain. At the time the signals left its host galaxy, Earth would have been two billion years old, less than half its current age. The fast radio burst FRB 121102 emanates from the galaxy pictured. (Gemini Observatory/AURA/NSF/NRC)Scholz said that there could be reasons such as the signal being distorted between its source galaxy and Earth.
