    China’s Chang’e-6 reveals why solar wind hits the Moon’s two sides differently

    China’s Chang’e-6 samples have uncovered a surprising difference between the Moon’s two hemispheres. Solar wind particles penetrated deeper into the far-side soil because Earth’s magnetosphere slows the particles that reach the near side. Noble gases locked inside the lunar regolith preserved evidence of this uneven bombardment. These gases may even help scientists reconstruct the ancient history of Earth’s magnet...
