Modeling offers new perspective on how Pluto's 'icy heart' came to be
Pluto's icy heart is a bright, two-lobed feature on its surface that has attracted researchers ever since its discovery by the NASA New Horizons team in 2015. Pluto's basin is significantly larger than the volume of ice it contains today, suggesting that Pluto's heart has been slowly losing mass over time, almost as if it was wasting away. Even so, the single ice cap represents an enormous weight on Pluto's surface, enough to shift the dwarf planet's center of mass.
