MU69 appears as a bi-lobed baby comet in latest New Horizons images
The tiny world 2014 MU69 is far behind New Horizons now and no longer visible to its cameras. Now, New Horizons’ task is to return its precious data to Earth. The process will take 20 months, but the best images should all arrive between now and the end of February. Some early ones have come down from the spacecraft in the hours since the flyby. These are not the best we will get, but they already show us much about MU69: this is probably what comets look like, before they become comets.
