A recently detected SETI signal could end up being this generation's versionof the famous "Wow!" signal of 1977: an intriguing mystery that keeps astronomers guessing for decades.
In May 2015, a team of researchers using a Russian radio telescope spotted a strong radio signal coming from the vicinity of the sunlike star HD 164595, which lies 94 light-years away from Earth.
The signal is consistent with something an alien civilization might send out, astronomers have said. But that's just one scenario, and not the most likely one, researchers cautioned; the signal may also have resulted from a natural celestial event or terrestrial interference of some sort.
