Astronomers from Columbia University have reported the possible discovery of the first exomoon – but they stress that it is still unconfirmed and just a candidate at this point.

Fly over Pluto and Charon for second anniversary of New Horizons’ historic visit

To help celebrate the occasion, NASA has posted a new video of the epic flyby, when the spacecraft soared over the tall mountains and vast icy plains of this small but active world.
