Concerns a dimming star light years away may be due to a new alien civilisation is now believed to be due to a natural phenomenon
The dimming of a star, which had led to concerns large alien structures could be shadowing it, is now believed to be the result of a natural phenomenon, experts say.
The Seti Institute, which searches for extra-terrestrial intelligence, has been investigating the possibility of an alien civilisation.
They used the Allen Telescope Array to look for relatively wide-band signals, a type of emission that is generally not considered in SETI searches.
Seti says analysis of the Array data shows no clear evidence for either type of signal between the frequencies of 1 and 10 GHz
Seth Shostak, a veteran searcher for alien-life at the Seti Institute, says this suggest a “natural” phenomenom rather than the suggestion of alien life.
“The history of astronomy tells us that every time we thought we had found a phenomenon due to the activities of extraterrestrials, we were wrong,” he said.
“But although it’s quite likely that this star’s strange behaviour is due to nature, not aliens, it’s only prudent to check such things out.”
The group is going to continue monitoring the situation.
