In 1977, scientists shot into space some gold hoping to communicate with aliens and nowadays, scientist’s teleport things into space. Particularly, two golden records have images and sounds that would try representing a version of the SparkNotes of the big blue dot we live on. Two of these discs made it on Voyager 1 and 2 to space and were never seen again.
Three years before the Golden Records launch, humans made a less gilded attempt at communicating; while a radio transmission having the basic information about humanity was sent from the Arecibo radio telescope into the cosmos in Puerto Rico.
Two major attempts and the earth received no radio waves in return until now. Scientists at the Arecibo Observatory, this is the center where humans attempted radio contact first with the greater universe, picked up radio signals just 11 light years away from a small red star.
The signals noticed red dwarfs during an examination. The reported signals source was placed in the Virgo constellation, particularly in a star area named Ross 128.
Radio waves stem from space regularly, but this signal particularly was structured in a way that was unheard of from a star. Solar flares produce radio signals, but this frequency particularly was much lower than the ones observed in flares.
The signal is exceptional, but could it be aliens? The possibility is not ruled out entirely, but it is much low on the ladder considering viable theories, as per Abel Mendez, at the University of Puerto Rico, the director of the Planetary Habitability Laboratory.
