Astronomers are looking into a possible sign of alien life.
They say a star around 94 light years from earth is emitting a very strong radio signal.
It was detected by a Russian telescope.
Astronomers are training their telescopes on the star in the hopes of learning more.
Researchers say if artificial-- the signal could be evidence of a hugely advanced alien civilization.
A type-two civilization would be able to harness the entirety of the energy emitted by its star, but would need a superstructure to do it.
That's more advance than our civilization.
Earth is type one on the scale, meaning we are able to harness all the energy available on our own planet including solar, wind, and other fuels.
