Dating lunar rocks open dating quality
The solar wind is a continuous stream of charged, highly energetic particles originating at the Sun and moving out in all directions.
The gases found in lunar samples match the isotope ratios expected for gas from this source, and are significantly different to isotope ratios found on Earth.
Where boots have tread: The Apollo 17 landing site, photographed by the Lunar Reconnaissance Orbiter, which revisited the moon in 2009.
“Thirty-five years ago,” says Hodges, “all we could really say ‘there’s been melting,’ but now we can look with much finer resolution.” The new analysis is based only on rocks from the Taurus-Littrow valley, where Apollo 17 touched down.
The principal evidence for the antiquity of Earth and its cosmic surroundings is: Spontaneous breakdown or decay of atomic nuclei, termed radioactive decay, is the basis for all radiometric dating methods.
Radioactivity was discovered in 1896 by French physicist Henri Becquerel.
This is completely opposed to the Earth’s environment at the time of formation, approximately between three and four and a half billion years ago.
Lunar rocks also contain trapped gases from the solar wind passing them at the time of formation.
