An 84,000 foot tall volcano the size of Arizona. A 300 mile high eruption plume. A 40 mile wide lava dome. These are all actual volcanic features which exist in the solar system, specifically on unusual worlds outside of Earth. Today's video will give a brief overview and discuss these worlds, which will include Venus, Mars, and Io.
