Moon was Formed in Massive Planetary Collision

  New study traces Moon evaporation and leads to questions about why Earth has so much water   Fresh examinations of lunar rocks gathered by Apollo mission astronauts have yielded new insights about the Moon’s chemical makeup as well as clues about the giant impacts that may have shaped the early beginnings of Earth and [continue reading]

Solar Wind Delivers Water to the Moon and other Solar System Bodies

  Three years ago University of Tennessee, Knoxville, researchers helped to discover water on the surface of the Moon. Now, they are piecing together the origin of that water: solar wind. This microscope image shows a grain of agglutinate glass similar to those analyzed in the lunar surface-water study reported in Nature Geoscience. The specimen [continue reading]

A New Perspective on the Moon's Formation

  The Moon is believed to have formed from a collision, 4.5 billion years ago, between Earth and an impactor the size of Mars, known as “Theia”. Over the past decades scientists have simulated this process and reproduced many of the properties of the Earth-Moon system; however, these simulations have also given rise to a [continue reading]

Walls of Lunar Crater Hold Patchy Ice

  Small patches of ice could make up at most five to ten percent of material in walls of Shackleton crater. Shackleton is an impact crater at the south pole of the Moon. The crater is more than 12 miles wide and two miles deep (21 km in diameter and 4.2 km deep). Image Credit: [continue reading]

Neil Armstrong -- the First Man on the Moon -- Dies

  A statement from his family says he died from complications from heart surgery he had to relieve four blocked coronary arteries on 7 August. The statement did not say where Armstrong died. Neil Armstrong. 1930-2012. Image Credit: NASA   He set foot on the Moon on 20 July 1969, famously describing the event as “one small [continue reading]

Moon's Formation a Hit-and-Run Scenario

  A new theory of lunar formation suggests Earth was the victim of a hit-and-run incident — and that the culprit may still be at large. Computer simulations suggest a large, fast-moving body impacted the Earth to create the Moon. The origin of the Moon is one of the more important problems for planetary geologists and [continue reading]
