Moon's Birth Was Fueled by Earth

The evidence comes in the form of isotopes of noble gases like helium and neon.

Researchers found these trapped in lunar meteorites recovered from the Antarctic. The isotopes match up with those found in solar wind, despite the meteorites reportedly never being exposed to it.

After all, NASA is still working to get humans back on the Moon over 50 years after the last human boots touched down on the lunar surface.

Thankfully, pieces of the Moon often make their way to us like meteorites. And, because the samples were from an area that never would have been exposed to the solar winds

Some of these meteorites provided the evidence researchers have been looking for.

The evidence, the researchers write in their paper, which was published in Science Advances

points toward the Moon containing similar isotopes found deep within the Earth’s mantle plumes, too.

They say all this shows that our satellite was birthed by a collision or explosion eons ago.

When digging deeper, the team found sub-millimeter glass particles in the basalt, which retained the isotopic signatures like little time capsules from eons ago.

they say the Earth very likely gave birth to the Moon, especially given that the isotopes so closely match those found in the deep Earth.
