Strange radio transmissions appear to be coming from our nearest star system; now scientists are trying to work out what is sending them
It’s never aliens, until it is. Today, news leaked in the British newspaper The Guardian of a mysterious signal coming from the closest star to our own, Proxima Centauri, a star too dim to see from Earth with the naked eye that is nevertheless a cosmic stone’s throw away at just 4.2 light-years. Found this autumn in archival data gathered last year, the signal appears to emanate from the direction of our neighboring star and cannot yet be dismissed as Earth-based interference, raising the very faint prospect that it is a transmission from some form of advanced extraterrestrial intelligence (ETI)—a so-called “technosignature.” Now, speaking to Scientific American, the scientists behind the discovery caution there is still much work to be done, but admit the interest is justified. “It has some particular properties that caused it to pass many of our checks, and we cannot yet explain it,” says Andrew Siemion from the University of California, Berkeley.
Most curiously, it occupies a very narrow band of the radio spectrum: 982 megahertz, specifically, which is a region typically bereft of transmissions from human-made satellites and spacecraft. “We don’t know of any natural way to compress electromagnetic energy into a single bin in frequency” such as this one, Siemion says. Perhaps, he says, some as-yet-unknown exotic quirk of plasma physics could be a natural explanation for the tantalizingly concentrated radio waves. But “for the moment, the only source that we know of is technological.”

There is a natural explanation probably,
A team of Cornell researchers detected radio bursts emanating from the sole exoplanet orbiting the Tau Boötes binary star system – making this the first radio emission received from a planet outside of our solar system.

There are also signals coming from Tau Bootis.

As charlyv said, any civilization that can communicate in the radio spectrum will go spread spectrum digital and not stay in the radio frequency range for any length of time for us to notice (we did the same. About to go terahertz, digital spread spectrum, so why would aliens stay at one level of technology?)
Besides, I thought we already went there and only found primordial goo.
Cool thoughts though!!
Because They are out there! And already here...

Open a subspace channel then.
Fire up the ansible.
