“The half heart glacier lying inside is a really massive glacier, which is not impacted by the seasonal changes. It probably formed when the basin formed, and will remain there in the future,” Bertrand said. “However, it probably flows and retracts over a few hundreds of kilometers (like a heart beating) with time, eroding and shaping the mountains surrounding it.”
By watching Pluto over decades to see if the model’s predictions come true, the researchers will either confirm the model or figure out ways to adjust it. It’s possible we’ll discover a more volatile world than we expected.
