Research sheds new light on intelligent life existing across the galaxy

No actual evidence for alien civilizations is provided or implied; it’s just another estimate based on assumptions. The conclusion reached here is that there may be around 30 intelligent, communicating technological civilizations in the galaxy right now… separated by an average of about 17,000 light years.

Which means there ain’t nobody to hear just now. If a powerful radio transmission was directed straight at us using a radio telescope, we could pick it up from tens of thousands of light years away, so long as we were listening at the right time and in the right direction. But transmissions such as commercial radio and television? Likely swamped by natural radio emission within a mere light year or two. Summary: unless and until some current-physics-defying tech comes available – warp drive, hyperspace comms, that sort of thing – the universe will likely remain empty-looking.
