After providing the world with spectacular close-up images of Pluto and its icy moons in the summer of 2015, NASA’s New Horizons is zipping off into uncharted territory a billion miles away. On January 1, 2019, the spacecraft will fly past the most remote world ever explored by mankind. Dubbed (486958) 2014 MU69, the small frozen object, which lies in the Kuiper Belt, may help scientists reveal the origins of our solar system. To mark this historic event, the US space agency is asking the public to help find a nickname that is easier to remember than the elaborate moniker assigned by scientists.
