Mons Hansteen: A Window into Lunar Magmatic Processes

Oblique view of Mons Hansteen, located near the southern margin of Oceanus Procellarum at 12.3° S, 309.8° E. This enigmatic landform is thought to be a volcanic complex and one of only a handful of known sites on the Moon composed of...

NAC Anaglyph: Maunder Central Peak

Maunder Central Peak - created when Maunder crater (55 km in diameter) was formed.  The central portion of the crater was initially compressed, then subsequently rebounded to form these large peaks which rise over a kilometer above...
