| It’s still too early to tell if the signal is coming from an extraterrestrial civilization, but the researchers say it’s serious enough that scientists should now permanently monitor this new target. HD164595 is practically the same size and age as our own sun, it shares a similar chemistry, and it’s less than 100 light-years away. What’s more, it hosts at least one known planet, a warm Neptune in a circular orbit. It’s very possible that other planets reside within this system. Looking at the signal, the researchers say that if it came from a multi-directional, isotropic radio beacon, it would have to be produced by a Kardashev Type II civilization, i.e. an alien civilization that has tapped into nearly 100 percent of its host star’s energy potential. If the signal was targeted directly at our solar system, then it would be of a power available to a Kardashev Type I civilization, i.e. an alien civilization capable of exploiting nearly all of its home planet’s energy potential. Another possibility, of course, is that the signal is a natural anomaly, such as background noise. French astronomer Jean Schneider is considering the possibility that HD164595 is amplifying a background radio source through a process known as gravitational microlensing. |
The Wow Signal may have been caused by a comet. We'll know more in 2017.

Unfortunately, there is no money in a natural anomaly, so I look at these claims with more than a little skepticism.
Worth noting that it's not definitively the only planet in that system.
Maybe that's why the planet is so big.

The planet has a mass 16 times that of Earth, and completes an orbit every forty days. So it is not in the habitable zone.

Agreed.
