Full Moon...full of Earth fossils? Credit: NASA/JPL

New research suggests that it is possible that terrestrial rocks ejected from the Earth by giant impacts from space — and which then strike the Moon — may successfully transfer terrestrial fossils to the Moon. The results were obtained from hypervelocity impact experiments which fired fossilized diatoms frozen in ice into water targets. Diatoms are […]

Europa harbors a global ocean covered by an ice shell. Indeed, that large reservoir of liquid water has long enchanted planetary scientists with the possibility that the moon is also a harbor for life. On one hand, NASA does place high programmatic priority on this prospect to further the potential for a future lander mission […]

This image is one of the highest resolution images taken to date by the MESSENGER spacecraft. It features a field of secondary craters in Mercury

NASA’s MESSENGER – short for MErcury Surface, Space ENvironment, GEochemistry, and Ranging – has moved closer to Mercury than any spacecraft has before. The spacecraft has been maneuvered to an altitude at closest approach of only 100 kilometers (62 miles) above the planet’s surface. “This dip in altitude is allowing us to see Mercury up […]
