According to a report by Business Insider, the most distant object humanity has ever visited looks a little bit like a spinning hourglass lost in space. Researchers from NASA's New Horizons mission released video Tuesday showed the rotation of the mountain-sized rock, formally known as 2014 MU69, but referred to by NASA as Ultima Thule. Mu69 is roughly 4 billion miles from Earth and 1 billion miles beyond Pluto.
