Astronauts on the International Space Station were in the right place at the right time.
The station passed over a volcano as it erupted two weeks ago and astronauts snapped pictures. The volcano is in a chain of Russian islands northeast in the north Pacfic Ocean.
The white cloud in the middle of the eruption is called a pileus cloud, according to NASA. It probably formed during the rapid rising and cooling of the air mass over the ash column.
The volcano has erupted with lava flow three times since 1976. The last explosive eruption occurred in 1989, according to NASA.
