Our favorite star is at it again, KIC 8462852, also known as Tabby’s Star. For those of you who do not know about Tabby’s Star, it is a star that does not act like other stars. Tabby’s Star has been showing strange patterns in brightness since its discovery. The star has strange dips in light which was initially thought to have been a planetary system, however the light dips are far too deep for that. Others theorize that it is a massive cloud of gas or even comets, however that has now been ruled out as well.
Back in 1977 Astronomer Jerry Ehman was using the Ohio State University’s Big Ear Radio Telescope sweeping for potential signals from alien civilizations. While monitoring the skies he came across a very powerful signal that lasted for exactly 72 seconds coming from the area of Chi Sagittarii. Dubbed the WOW signal because he circled the numbers and letters on a printed readout and wrote Wow! next to it.
