The space agency wrote on its LROC site: “While not entirely clear without a better understanding of melt pond dynamics for still-molten deposits, we note that moderately viscous materials can behave in odd ways.
“The isolated occurrence of individual domes suggests molten behaviour with each dome forming in-situ from a local source just beneath its position.
“Since the phenomenon is occurring in impact melt, we would be wrong to call this behaviour volcanic.
“But something similar to volcanism in the sense that molten rock is locally ‘erupting’ from an accumulated ... Read even more
