Healthy extreme scepticism is the best summary. It’s obviously the least likely reason for BLC1.

It’s a message from a technologically advanced civilization living on one of the two planets known to be orbiting our nearest stellar neighbor.

After all, space is big. So it may not be from a nearby star anyway.

The radio signal is coming from behind Proxima Centauri-possibly millions of light-years beyond.

The source is natural, but unknown-maybe it’s a really odd kind of quasar (a supermassive black hole) or pulsar (a highly magnetized rotating compact star) that emits narrowband radio signals.

Extraterrestrial technology exists in space because we put it there-it could be from a satellite or a spacecraft.

After all, it’s got all the hallmarks of being artificial and having a technological source. Since we use radio, it could well be interferences-the signal could have originated on Earth.There are lots of opinions-and most of them suggest something other than you-know-what: Universal Images Group via Getty Images What do experts think the signal is? naked eye-close to Alpha Centauri, a star mostly visible from the southern hemisphere. The Proxima Centauri star system is just 4.24 light-years from us and is found-though not with the. However, until scientific papers are published-something that is expected soon-the signal’s profile, strength and modulation remain unknown. It was also only detected once over 30 hours in April and May, 2019. It occupied the 982 MHz radio spectrum, which is normally used by satellites and spacecraft.

What is strange about ‘BLC1?’īLC1 was a very narrow band radio signal. However, BLC1 is not a dimming star, but a radio signal that appears to have a technological source. Was it an alien megastructure around the star periodically blocking its light? Probably not. Boyajian detected the mysterious dimming of a star called KIC 8462852-henceforth nicknamed “ Tabby's Star”-1,470 light-years distant in the constellation of Cygnus. The most recent conversation about technosignatures occurred in 2015 when astronomer Tabetha S. What form do they take? Nobody has a clue. “Technosignatures” or “technomarkers” are signs of technology developed by intelligent life elsewhere in the Universe.
