Upcoming telescopes will give us more power to search for biosignatures on all the exoplanets we’ve found. Much of the biosignature conversation is centered on biogenic chemistry, such as atmospheric gases produced by simple, single-celled creatures. But what if we want to search for technological civilizations that might be out there? Could we find them by searching for their air pollution?…

Did the Wow! signal come from this star?
Where did the famous mystery Wow! signal, detected in 1977, come from? Astronomer Alberto Caballero might have pinpointed the host star. It’s a sunlike star 1,800 light-years away, in the direction to the center of our Milky Way. Source: https://earthsky.org/space/source-of-wow-signal-in-1977-sunlike-star-2mass-19281982-2640123…
U.S. Presidential Candidate Addresses Questions About Extraterrestrial Invasion
If you’re worried about invasions from outer space (or from inside the Earth or from another dimension), you may want to listen to what U.S. presidential candidate Seth Moulton (another one?) has to say about how he would handle the situation if he was sitting in the Oval Office. Will this become one of the… Read more » Source: https://mysteriousuniverse.org/2019/04/u-s-presidential-candidate-addresses-questions-about-extraterrestrial-invasion/…
Scientists Suggest We Could Be Living In A “Galactic Zoo” Run By Aliens
Members of METI (Messaging Extraterrestrial Intelligence) gathered in Paris last week to talk about aliens and what they came up with is quite interesting to say the least. They mentioned that although researchers have been searching the skies for many decades, there is a lack of actual evidence proving that aliens exist. Since there are… Continue reading Scientists Suggest We Could Be Living In A “Galactic Zoo” Run By Aliens
