Recently? I've been hearing about a possible large trans-Pluto object since before Pluto lost its status as a planet.
I must not be on the more scientific news places then, I didn't start hearing about it until around last year--maybe the year before--, well after pluto got thrown out like last night's trash.
There's been "planet X" theories since the 50s
