So what exactly had the Russians seen? The spike in radio signals came from HD 164595, which is a star 95 light years away. Astronomers already know that there is at least one planet, a kind of “warm neptune,” orbiting that star – but there may be others as well.
Interestingly, HD 164595 is very similar to our own sun. In fact, it is only slightly hotter than ours and is also about the same age. Relatively speaking, that is, as our sun is around 100 million years older than HD 164595.
Naturally, then, astronomers are now trying to figure out what exactly the signal means. For obvious reasons, most are holding onto the conservative possibility that it’s a completely natural occurrence: something has happened out there, and we’re picking up the impact over the radio.
