Some of you have certainly already read the news of the strong signal received last year (and only just now reported to the general public) from 94 light years away. Finnish media put up a few articles of space and signals and how unlikely it was that intelligent life was anywhere.
The signal was picked up by an international team of researchers with a RATAN-600 telescope in the Russian Caucasus. The source appears to be at or near a star named HD164595 in the constellation of Hercules.
The star is 0,99 solar masses and approximately 6,3 billion years old. The metal structure and temperature are also rather similar to our Sun.
HD164595 is orbited by at least one planet. It is thought to be a warm Neptune type planet of 0,05 Jupiter mass with an orbital period of forty days. Obviously this planet is too close and likely too warm to support life (unless we start thinking SciFi). Other planets in the system have neither been confirmed or ruled out.
If it was the work of an advanced civilization, they would have to have advanced to at least I or II on the Kardashev Scale. As we know, human civilization is still at 0. There is nothing yet to merit such claims – and the scientists behind the find are the first to remind us so. They encourage more study of the star in question in hopes of a repeated observation.
It has also been brought to general knowledge that the frequency of the transmission is the same as is used by military transmissions and that there might be military satellites in orbit that SETI scientists do not know about that might cause such interference. (Seriously though, are military satellites really that much more important than the possibility of intelligent life in space? Make peace, not war!)
I truly do hope that more research is pointed that way. As some have said, this is one of the strongest SETI candidates in long time, and as such further study is definitely merited. If only to disprove the chance and to free the resources to other uses.
94 light years is a long time, on the other hand. It might be that if the signal was intentional the civilization that produced it exists no more. Who knows what kind of natural disasters are possible on faraway planets, not even taking into accord other dystopian possibilities.
Definitely something I’ll be keeping an eye on.
