New Moon: LRO Discovers Evidence of Young Lunar Volcanism

A series of surface features called irregular mare patches that have been recently discovered on the Moon, are thought to be remnants of small basaltic eruptions that are indicative of lunar volcanic activity as recent as several million years ago. This image by the Lunar Reconnaissance Orbiter shows one such feature, called Maskelyne. Image [...]

New Study Points to Alternative Origin for the 'Man in the Moon'

Oceanus Procellarum, or Ocean of Storms, an expansive flat basaltic basin that covers approximately 17 percent of the Moon’s near side, is surrounded by a series of linear gravitational anomalies (shown in red), as revealed by NASA’s GRAIL spacecraft. These anomalies indicate that the large basin was formed by volcanic processes rather than an [...]
