In published published in science journal Earth and Planetary Science Letters a sample collected during the 1971 Apollo 14 lunar mission the moon.
                                

Researcher Professor Alexander Nemchin

The sample was on loan from NASA to Curtin University, where it was researched in cooperation with researchers from the Swedish Museum of Natural History, Australian National University, and Lunar and Planetary Institute, Houston.

from Curtin's School of Earth and Planetary Sciences, which said: "The sample also contains quartz, which is even more unusual find on the moon, "Professor Nemchin said.

" By determining the age of zircon found in the sample, we were able to pinpoint the age of the host rock at about four billion years old, making it similar to the oldest rocks on Earth.

"In addition, the chemistry of the zircon in this sample is very different from that of every other zircon grain ever analyzed in lunar samples, and remarkably similar to that of zircons found on Ea rth. "

Professor Nemchin said that it was formed at low temperature and probably in the presence of water and oxidized conditions.

However, a simple explanation is that, "said Professor Nemchin.

" However, a simple explanation is that This is what happened on the Earth as it asteroid hitting Earth about four billion years ago, and throwing material into space and to the moon.

"Further impacts on the moon at Later on, Apollo 1

4 landing site, where it was collected by astronauts and brought back home to the Earth. "
