We can frequently use our understanding of Earth to spell out what we see {} worlds, though we might need to update the physics into account for another temperature or even a tenuous atmosphere. But planetary scientists can not always presume that a recognizable landscape attribute shaped in a comfortable way.
As soon as the New Horizons spacecraft gave us {} close-up look at Pluto, there were also still extraterrestrial wonders. However there were mountaintops dusted with some glowing, appearing quite like Earth’s snowcapped peaks. On Earth, these snow covers are made by improved precipitation as air rises over the hills and warms, together with the colder temperatures in higher elevations.
On Pluto, this excuse can not do the job, for many reasons. To begin with, temperatures usually raise because you move up a couple of km from Pluto’s surface due to gases absorbing solar power. Winds also often dismiss downslope because the colder surface emphasise that the atmosphere close to it, which makes it sexier. So what kinds the glowing light and how can it arrive?
