Providence, Rhode Island |November 10, 2006| Conventional wisdom
suggests that the moon has seen no widespread volcanic activity
for at least the last three billion years. Now, a fresh look at
existing data points to much more recent release of lunar
gasses. The study, published in the journal Nature by geologists
Peter Schulz and Carlé Pieters of Brown University and Matthew
Staid of the Planetary Science Institute, uses three distinct
lines of evidence to support the assertion that volcanic gas has
been released from the Moon's surface within the last one to ten
million years. The researchers focus on a D-shaped area called
the Ina structure that was first recognized in images from
Apollo missions. The unusual sharpness of the features first
called Schultz's attention to the area. "Something that razor
