Tabby's Star and PDS 110

First of all, Tabby's Star is dimming again.

And we've found another dimming star, although this one likely has a far more prosaic explanation - a 30% drop in the light from PDS 110 for 2 to 3 weeks every 808 days.

The explanation: A large planet with rings. They think it might have very big rings. As PDS 110 is a young star, there likely aren't any habitable planets around it yet. The next "eclipse" will take place in September 2017 and they're hoping to confirm what's going on. Large rings? Moons in formation? We'll see!
