"Such knowledge might help scientists in geochemistry and geophysics to create new models that show more generally how such most volatile elements can survive planet formation, in our solar system and beyond." "While such gases are not necessary for life, it would be interesting to know how some of these noble gases survived the brutal and violent formation of the moon," Busemann said. He thinks that researchers will soon be looking to meteorites to find other noble gases like xenon and krypton that are more challenging to identify than helium and neon. "I am strongly convinced that there will be a race to study heavy noble gases and isotopes in meteoritic materials," Henner Busemann, a geochemist at ETH Zurich, said in the same statement. Meteorites in Mississippi reported after loud fireball overhead LUNAR ROCK FREEThe moon's mantle rocks also have a similar composition to those of Earth, and these rocks are both significantly different from Martian meteorites.

Other lines of evidence that support this theory include the fact that the moon is lightweight, lacking large amounts of iron in its interior, while 30% or so of Earth's mass is sealed in its iron-rich core. The impact must have been truly massive to throw out ejecta from Earth's interior that was able to remain in orbit and coalesce into another body, rather than falling back down to our infant planet. One version of the giant impact theory proposes that a protoplanet called Theia smashed into Earth around 4.5 billion years ago, about 60 million years after the Earth itself formed. The finding supports the idea that a giant impact created the moon, and the work could also lay a roadmap for research into how the solar system's rocky worlds formed. ![]() "Finding solar gases, for the first time, in basaltic materials from the moon that are unrelated to any exposure on the lunar surface was such an exciting result," Will said in a statement. ![]() (Mass spectrometers sort out by weight elements within a sample.) Scientists were able to catch the fingerprints of helium and neon in the meteorites thanks to a particularly sensitive noble gas mass spectrometer that researchers nicknamed Tom Dooley after a Grateful Dead song. ![]()
