An additional clue to the Moon’s origin.
The Moon has always been a topic of interest for humans. But it wasn’t until Galileo’s time that researchers started to study it seriously. Throughout the course of nearly five hundred years, researchers have proposed a variety of, highly contested ideas as to how the Moon was formed. Geochemists, cosmochemists, and petrologists from ETH Zurich have now shed new light on the Moon’s origin story.
The research team’s findings, which have recently been published in the journal Science Advances, demonstrate that the Moon acquired the indigenous noble gases helium and neon from the Earth’s mantle. The finding strengthens the already tight constraints on the widely accepted “Giant Impact” theory, which theorizes that Earth and another celestial body collided violently to form the Moon.
Meteorites from the Moon to Antarctica
Patrizia Will examined six samples of lunar meteorites from an Antarctic collection that NASA provided for her doctoral work at ETH Zurich. The meteorites are made of basalt rock, which was created when magma welled up from the Moon’s interior and quickly cooled. After they formed, additional layers of basalt proceeded to cover them, shielding the rock from cosmic rays and, in particular, the solar wind. The cooling process resulted in the creation of lunar glass particles amongst the other minerals found in magma.
Will and the team found that the glass particles still had helium and neon chemical fingerprints (isotopic signatures) from the Moon’s interior. Their results provide compelling evidence that the Moon inherited the gases indigenous to the Earth. “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,” says Will.
Without the protection of an atmosphere, asteroids constantly pelted the Moon’s surface. It likely took a high-energy impact to eject the meteorites from the middle layers of the lava flow similar to the vast plains known as the Lunar Mare. Eventually, the rock fragments made their way to Earth in the form of meteorites. Many of these meteorite samples were picked up in the deserts of North Africa or in, in this case, the “cold desert” of Antarctica where they are easier to spot in the landscape.
Grateful Dead lyrics inspire lab instrument
In the Noble Gas Laboratory at ETH Zurich resides a state-of-the-art noble gas mass spectrometer named, “Tom Dooley” – sung about in the Grateful Dead tune by the same name. The instrument got its name, when previous researchers, at one point, suspended the highly sensitive equipment from the ceiling of the lab to avoid interference from the vibrations of everyday life.
Using the Tom Dooley instrument, the research team was able to measure sub-millimeter glass particles from the meteorites and rule out solar wind as the source of the detected gases. The helium and neon that they detected were in a much higher abundance than expected.
The Tom Dooley is so sensitive that it is, in fact, the only instrument on Earth capable of detecting such minimal concentrations of helium and neon. It was used to detect these noble gases in the 7 billion years old grains in the Murchison meteorite – the oldest known solid matter to date.
Searching for the origins of life
Knowing where to look inside NASA’s vast collection of some 70,000 approved meteorites represents a major step forward. “I am strongly convinced that there will be a race to study heavy noble gases and isotopes in meteoritic materials,” states ETH Zurich Professor Henner Busemann, one of the world’s leading scientists in the field of extra-terrestrial noble gas geochemistry. He anticipates that soon researchers will be looking for noble gases such as xenon and krypton which are more challenging to identify. They will also be searching for other volatile elements such as hydrogen or halogens in the lunar meteorites.
Busemann comments, “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. 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.”

Why not believe that the moon was created by God? Its origin is God. If there is no God who is sovereign enough to control the very very complex yet beautiful universe, we are in a total mess.
I believe. The creator who made the moon told us He did so on day 4. For us to believe this we have to trust the creator. We have to look at creation and come to the conclusion that there is one who made who is above us. He gave us his word so we know who he is. Thanks for sharing…
What we do know about the moon to be a fact is that it will be turned into blood. The cow jumped over astronauts landed man probe and poke. God knows all things and thank you God for not given your glory to noone else. For it is written he made the firmament, heaven and earth. The moon is to guide us at night but pretty soon God will fill the heavens with his Glory! John saw the vision and I will see the fulfillment. Come Lord Jesus the spirit and bride say come. Mark the perfect man on this day!
The moon Is hollow and base for extraterrestrial races. So, it was put there by as liens !!!! Artificial thing.
No problem at all ‘believing’ that GOD created THE UNIVERSE and ‘everthing’ contained within it. What’s ‘problematic’ is ‘the account of CREATION’ as given and stated in ‘the Book of Genesis’. As ‘beautiful & interesting & sometimes educational’ as the ‘writings in the Bible’ can and may be, when all is said and done, they ‘must be’ recognized and/or dismissed for ‘the mythology’ they represent and actually are…unfortunately.
Arguing with ‘HOLIER-THAN-THOU’…’Bible-thumping’ religious fanatics is a ‘royal-waste-of-time.’
And they ‘wonder why’ the younger generations are so skeptical of ‘them’ […the HOLIER-THAN-THOU’ers…] and ‘the overly generous tax-breaks’ they receive from the IRS…while ‘the rest of us’ foot ‘their bills’ (…the ‘leeches’…shame…Shame…SHAME…). Tysk…tysk.
Have a nice day.
P.S.: For GOD ‘so loved’ the 🌎 World that ‘he gave’…etcetera…etcetera…
etcetera. (I’ll ‘assume’ you know the rest…).
We already know Santa isn’t real stop hiding the other truths from us, powers that be. We know all the lies you tell to cover all the wrong you do at the tax payers expense. One day you will pay for all the grief & hardships you’ve made the human race endure,by your lies and manipulation of the truth. There will be no mercy on your souls corrupt ones.
