LEFT: Sarychev Peak on Matua Island is one of the most active volcanoes in the Kuril Island chain, northeast of Japan. Astronauts aboard the International Space Station took this photo of an eruption on June 12. The plume appears to be a combination of brown ash and white steam. The vigorously rising plume gives the steam a bubble-like appearance; the surrounding atmosphere has been shoved up by the shock wave of the eruption.
