Lunar Surface Protected by 'Deflector Shields'

  Scientists from RAL Space at the Rutherford Appleton Laboratory have solved a lunar mystery and their results might lead the way to determining if the same mechanism could be artificially manipulated to create safe havens for future space explorers.  Their work focussed on the origin of the enigmatic “lunar swirls” – swirling patches of [continue reading]

Ancient Meteorites Give New Clues to the Early Solar System

  In order to understand Earth’s earliest history–its formation from Solar System material into the present-day layering of metal core and mantle, and crust–scientists look to meteorites. The diogenites originated deep within the crust of Vesta and resemble rocks, both in texture and composition, which we find in the lower crust of the Earth. The [continue reading]

Ancient Asteroid Produced Largest and Oldest Lunar Basin

  A new NASA Lunar Science Institute study suggested an asteroid, approximately 170 kilometers (105 miles) in diameter, striking surface of the Moon at nearly 40,000 kilometers (25,000 miles) per hour, produced the largest and oldest basin on the Moon and arguably the oldest surviving impact crater in the Solar System. The impact crater is [continue reading]

Water Ice at the Moon’s South Pole

  Scientists map Shackleton crater, whose unusually bright floor may hint at the presence of ice. Shackleton is an impact crater at the south pole of the Moon, that may have water ice. The crater is more than 12 miles wide and two miles deep (21 km in diameter and 4.2 km deep).   If [continue reading]

Nanoparticles Explain Weird Lunar Soil Behaviour

  A stunning discovery by QUT soil scientist Marek Zbik of nano particles inside bubbles of glass in lunar soil could solve the mystery of why the moon’s surface topsoil has many unusual properties. 3D image obtained using Transmission X-Ray Microscope (TXM), shown here as the anaglyph, reveals fine structure within vesicle in the lunar [continue reading]

Researchers Detect Remnants of Ancient Asteroids on the Moon

  NASA Lunar Science Institute’s LPI-JSC *) team made a fascinating discovery related to the lunar impact cataclysm hypothesis and the delivery of material to the Earth-Moon system just before the earliest evidence of life on Earth. NASA curation laboratory photos of the Apollo 16 regolith breccias and lunar meteorites that contain projectile debris. The [continue reading]
