Last month we brought you the remarkable story of KIC 8462852, a star being orbited by strange objects. Scientists were so confused by the anomalies in there data that some were speculating that “alien megastructures” were the cause.
“Aliens should always be the very last hypothesis you consider,” said Penn State astronomer Jason Wright. “But this looked like something you would expect an alien civilization to build.”
Well, upon further investigation, scientists have determined that the “alien megastructures” hypotisis was probably a load of bantha fodder.
According to the Independent:
In order to test the idea of an advanced alien civilization, scientists at Seti trained a radio-listening instrument called the Allen Telescope Array on the star for more than two weeks in search of two types of radio waves – “narrow-band” signals of the sort an alien society might use to hail other intelligent civilizations in the galaxy, and “broad-band” signals that might be due to a beamed, spacecraft-propulsion system.
Unfortunately for supporters of the alien-life theory, the Seti institute failed to find clear evidence for either type of signal produced by artificial transmitters that would need to be between 100 and 10 million times the power of radio transmitters used today on Earth.
“[A]lthough it’s quite likely that this star’s strange behavior is due to nature, not aliens, it’s only prudent to check such things out,” Dr. Seth Shostak of the SETI Institute told the Independent.
While scientists are confident that the anomaly is the result of natural causes, they are still uncertain as to what those causes may be.
