Even 10 years after initial detection, cosmic radio waves have always left astronomers scratching their heads, with some believing that they are tied to extra-terrestrial life.
Now, the strange bursts of energy have been linked to a dwarf galaxy over 3 billion light years from Earth.
Some suggested these mysterious bursts of energy could be a sign of alien life trying to contact us.

Now the signals have finally been tied to a source - a dwarf galaxy more than 3 billion light years from Earth.
These bursts, known as Fast Radio Bursts, or FRBs, were first discovered in 2007. Due to their random nature, it has taken a while for astronmers to conclude that they are anything other than mere glitches.
It was the repeating burst found in 2012 that led a team of researchers at the University of California, Berkeley and Cornell University to keep regular tabs on its surrounding area.
Cornell University's Shami Chatterjee said: "We now know that this particular burst comes from a dwarf galaxy more than three billion light-years from Earth.

"That simple fact is a huge advance in our understanding of these events."
Casey Law, of UOCaB, said: "For a long time, we came up empty, then got a string of bursts that gave us exactly what we needed."
"We are the first to show that this is a cosmological phenomenon. It's not something in our backyard. And we are the first to see where this thing is happening, in this little galaxy, which I think is a surprise," Law added.
"Now our objective is to figure out why that happens."
