Evidence for Hot Start And Early Ocean Formation on Pluto

The accretion of new material during Pluto's formation may have generated enough heat to create a liquid ocean that has persisted beneath an icy crust to the present day, despite the dwarf planet's orbit far from the sun in the cold outer reaches of the solar system.

SOFIA Finds Hidden Clues in Pluto's Haze

Observations made with the Stratospheric Observatory for Infrared Astronomy (SOFIA) -- a Boeing 747SP jetliner modified to carry a 106-inch diameter telescope -- help explain how Pluto's haze is formed and how the distant Sun affects the dwarf planet from 3.7 billion miles away.
