Volcanology

Physicists have identified the role of carbon-containing molecules in determining charge polarity during particle collisions in volcanic ash clouds. This discovery explains the triboelectric effect that leads to volcanic lightning. The finding comes from experiments with silicon dioxide particles.

A new study reveals that a volcano south of Pavonis Mons on Mars formed through multiple eruptive phases powered by an evolving magma system, challenging earlier assumptions of a single eruption. Researchers used orbital imaging and mineral data to trace the volcano's development. The findings indicate Mars's interior was more active than previously thought.
