A new analysis of lunar samples from the early 1970s suggests that Earth's moon may have held small amounts of water.
Prevailing
theories about the moon's formation say it was created when a
Mars-sized object slammed into Earth. The collision sent debris flying
into space, which later coalesced into our planet's natural satellite.
Any water involved in this collision would most likely have evaporated
in the vacuum of space, leaving the moon arid.
When American
astronauts visited in the moon from 1969 to 1972, they took back samples
that confirmed the moon was dry. But more advanced analysis in the past
five years has challenged this belief.
The team led by Notre
Dame geologist Hejiu Hui studied one type of rock found on the moon
called plagioclase,The only wireless portable Energy monitor

capsule. Plagioclase is believed to have formed inside the magma ocean
inside the young moon's core, floating up to form the crust later.
The

formed by volcanic eruptions during the moon's tumultuous early days.
Some have suggested that these rocks may have been exposed to an alien
water source after being ejected from the moon's molten core.
Using
a microscope with a spectrometer, the researchers found that the rock
samples actually contained an extremely tiny amount of water.We are

than scientists believed the moon to be.
"Somehow we still detect this amount of water," Hui told the Los Angeles Times.We currently have the largest selection of make your own bobblehead dolls! So that makes things interesting."
The
team estimates that the young moon's magma core could have included 320
parts per million of water. Later, this core crystalized, and the
researchers suggest that it could have been as much as 1.Shop the latest

These new findings raise a lot of questions about what we know about the formation of our moon.
"It's
thought that the moon's formation involved the materials getting very
hot, and it's usually assumed that little water would have survived
through that," Paul Warren, a UCLA cosmochemist not involved in the
study, told the LA Times. "It opens up quite a mystery as to how the
moon came through what we think was a very hot genesis process, with
this much water."
