There are giant ice blades on Pluto? Who knew?
Pluto’s surface hosts blades of ice that soar to the height of skyscrapers — and researchers have narrowed down exactly how the dramatic features form….”When we realized that bladed terrain consists of tall deposits of methane ice, we asked ourselves why it forms all of these ridges, as opposed to just being big blobs of ice on the ground,” Jeffrey Moore, a New Horizons team member and lead researcher on the new work, said in a statement. “It turns out that Pluto undergoes climate variation and sometimes, when Pluto is a little warmer, the methane ice begins to basically ‘evaporate’ away.”
Pluto turned out to be much cooler than I’d have expected for such a tiny, cold planetoid.
