83 AU from Sol. But better yet? It appears to be gravitationally influenced by an unknown mass that could be up to 10 times the size of Earth.

250 km asteroid with not one, but TWO! rings of 3km and 7km width. Plus evidence that the rings are influenced by an unknown moon.

Polarization in the background radiation that bears the imprint of gravity waves is pretty much a smoking gun for the inflationary model of the big bang, and direct evidence of the existence of gravity waves. Very cool!
