The Lunar Reconnaissance Orbiter camera provides a glimpse into
our Moon's volcanically active past. This is Rima Prinz - a
long channel where lava once flowed from the Vera volcanic
depression. Within Vera, eruptions of fiery lava
fountains formed a lake of lava three hundred meters deep and
carved a lava channel a hundred times deeper and ten times
longer than ones on Earth. This region shows that eruptions on
the Moon were sometimes larger than what we see on Earth today.
