There is a star called "Tabby's Star", I learned of it due to several news sources on my phone mentioning it and talking about a strange anomaly it is giving off. It is flickering in unusual ways for a star.
Some news links are saying it's an asteroid field, but some claim that asteroids won't cause a star to flicker in a way that Tabby's Star does.
And some news sources say it could be alien megastructures.
Here is Michio Kaku talking about it.
Gotta admit, the reporter did get on my nerves. But Michio does sum up all the things I've been hearing so far on my phone's random news feeds. I thought it'd be interesting to share with you guys.
What do you think it is? Arcturians?
Here's a more recent video on the news.
