Scientists have been on the hunt for fast radio bursts, or FRBs, since they first detected one in 2007.
Since that first one was discovered, scientists have only found a few dozen more, but new research says these mysterious signals could be pinging around the universe every second.
Experts are still unsure exactly what these signals are, but what they do know is that they can emit as much energy in a second than the sun does in 10,000 years.
They are exceptionally difficult to study as they can last as little as a millisecond and there is no way to predict when they are coming.
Some experts says they are natural, such as exploding stars, while other scientists believe that they are extra-terrestrial signals which were intentionally sent Earth’s way.

Research carried out at the Harvard-Smithsonian Center for Astrophysics (CFA) found that FRBs are likely taking place constantly.
Anastasia Fialkov of the CFA, who led the study, said: “If we are right about such a high rate of FRBs happening at any given time, you can imagine the sky is filled with flashes like paparazzi taking photos of a celebrity.
“Instead of the light we can see with our eyes, these flashes come in radio waves.”
Co-author Avi Loeb added: “In the time it takes you to drink a cup of coffee, hundreds of FRBs may have gone off somewhere in the Universe.
“If we can study even a fraction of those well enough, we should be able to unravel their origin.”
To reach this conclusion, the team studied FRB 121102 – a signal that came from a galaxy around three billion light years away.
Several bursts have come from this galaxy since they were discovered, making it one of the few that they have been able to study.
By calculating the amount of FRBs detected by the sheer size of the universe and the amount of galaxies in it, the experts believe that FRBs could be happening every second, according to the research published in The Astrophysical Journal Letters.
Dr Fialkov said that the research could help unravel the mysteries of the universe.
She said: “FRBs are like incredibly powerful flashlights that we think can penetrate the fog and be seen over vast distances.
“This could allow us to study the ‘dawn’ of the universe in a new way.”
