A bunch of astronomers spotted something odd in the outer solar system. The formal announcement is tomorrow. Someone accidentally leaked the big reveal on Twitter, but deleted it before more than a few people could notice. There are hints that a known object is doing something very unexpected for something of its type and distance from the sun.
I'm still hoping for the announcement of a Mars-size planetary-mass object way out there, but the hints point to atmosphere where there shouldn't be any.
