Astronomers from NASA's Lunar Science Center have discovered what they believe to be dormant silicate volcanoes on the far side of the moon. NASA's most recent findings offer scientists a more direct understanding of the moon's volcanic activity.

From the NASA Lunar Science Institute:

Recent observations, made with the powerful Lunar Reconnaissance Orbiter (LRO) optical cameras, have allowed scientists to distinguish volcanic features in terrain at the center of the bull’s-eye. High-resolution three-dimensional models of the terrain and information from the LRO Diviner instrument have revealed geological features diagnostic not just of volcanism but also of much rarer silicic volcanism.

The volcanic province’s very existence will force scientists to modify ideas about the Moon’s volcanic history, says Bradley Jolliff, PhD, research professor in the Department of Earth and Planetary Sciences in Arts & Sciences at Washington University in St. Louis, who led the team that analyzed the LRO images.

“To find evidence of this unusual composition located where it is, and appearing to be relatively recent volcanic activity is a fundamentally new result and will make us think again about the Moon’s thermal and volcanic evolution,” he says. MORE
