AUSTIN—Astronomers are looking into a possible sign of alien life.
They say a star around 94 light years away is emitting a very strong radio signal detected by a Russian telescope.
Researchers say the signal could be evidence of a hugely advanced alien Type 2 civilization. A Type 2 civilization would be able to harness all the energy not just on their own planet, but from their star. People on planet Earth are a Type 1 civilization, which means we're able to harness all the energy on Earth including solar, wind and other fuels.
