Exploring Pluto, Charon & the outer reaches of the solar system

In 2015, the New Horizons spacecraft flew past icy Pluto and Charon and sent back the first images of these objects in the furthest outskirts of our solar system. I will review what we now know about Pluto and Charon, and how the study of these bodies has evolved. I'll also discuss the images received over the New Year from the much smaller icy object Ultima Thule.
