Independent: A new analysis of strange modulations in a tiny set of stars appears to indicate that it could be coming from extraterrestrial intelligence that is looking to alert us to their existence. by Andrew Griffin
'The new study reports the finding of specific modulations in just 234 out of the 2.5 million stars that have been observed during a survey of the sky. The work found that a tiny fraction of them seemed to be behaving strangely.
'And there appears to be no obvious explanation for what is going on, leaving the scientists behind the paper to conclude that the messages are coming from aliens.'
