Small iron nanoparticles, different from those found naturally on Earth, can be found practically all over the moon. Until now there was no explanation for this phenomenon, but a new study by scientists at the University of Northern Arizona, in the United States, shows that the Sun would generate these effects on the Moon. According to a press release , both asteroid impacts and solar radiation directly affect the Moon, because our natural satellite lacks the protective magnetic field and atmosphere that protect the Earth. Asteroids and solar radiation would have a strong influence on the lunar surface , much greater than that considered until today. Radiation from the Sun breaks down lunar rocks and soil, forming iron nanoparticles , which are detectable from instruments located on satellites orbiting the Moon. Since iron absorbs a lot of light, very small amounts of these particles can be identifie...
