Has the 40-year Old Mystery of the 'Wow!' Signal Been Solved? (newatlas.com)

"Astronomers have confirmed that the Wow! signal, thought to be the most promising detection by SETI of alien life, was actually caused by a comet," writes schwit1. New Atlas reports: Last year, a group of researchers from the Center of Planetary Science proposed a new hypothesis that argued a comet might be the culprit. The frequency could be caused by the hydrogen cloud they carry, and the fact that they move accounts for why it seemingly disappeared. Two comets, named 266/P Christensen and P/2008 Y2 (Gibbs), happened to be transiting through that region of space when the Wow! signal was detected, but they weren't discovered until after 2006. To test the hypothesis, the team made 200 radio spectrum observations between November 2016 and February 2017. Sure enough, 266/P Christensen was found to emit radio waves at a frequency of 1,420 MHz, and to double check, the researchers moved their radio telescope by one degree. As expected, the signal vanished, and only returned when the telescope was trained back on the comet.

    Maybe some poor bastard's been stuck on that comet for the last 40 years.

    So we thought that aliens were just emitting radio signals and we now discover that they are actually sending us comets.
    Very, very impressive.

    At this point. I have heard all sots of excuses for it. It has never been repeated. The odds of it being from an intelligent source, are REALLY fucking low. If they were gonna send us something, they'd probably send something with more bits, unless they figured we could (and would) decode it from that. Dunno but I bet any aliens sending messages aren't stupid. They're gonna make it easy to decode. Call it a hunch...

    Yeah, just a hunch... I could be wrong and an advanced alien species could be sending messages but making them difficult to decrypt because they're just jerks like that. Damned aliens.

    To put things in perspective, the Milky Way is about 100 000 light-years in diameter. The Sun is located about 25 000 light-years from the center. So far, the very first radio signal human made sent from the Earth hasn't reach that many solar systems. In a sphere of 49 light-years from the Sun, there is about 208 stars of absolute magnitude 8.5 and brighter. Keep in mind the strength of a radio signal is proportional to the inverse of the square of the distance between the sender and the receiver.

    No, quite the opposite. They might consider us way more advanced than we are.

    Take our Acecibo message. To decipher that message, you need to have a civilization with advanced radio equipment to detect it in the first place, with the capability to store it so it isn't just received and potentially missed, the knowledge of statistics to understand that this is actually not a natural phenomenon but a coded message, enough mathematical understanding to decipher it...

    And all that also pretty much assumes that they wanted to communicate with us. More likely, though, if this actually IS some sort of messaging system, we're just the natives sitting on our island while the interstellar cargo ships send messages in ways we can't even possibly understand, and what we see there might as well have been an explosion from a transformer that cooked off.
