A rock sample collected by the astronauts of Apollo 14 in 1971 from the surface of the Moon may be the oldest piece of the Earth, according to recent studies.
An investigation by an international team of scientists has revealed that the sample contains a fragment of an ancient crust that scientists believe is likely to have formed deep beneath the surface of the Earth.
Published in the journal Earth and Planetary Scientific Letters, the analysis found that the rock is composed of quartz, feldspar and zircon that are very common on Earth but are very unusual on the Moon.
Researchers have concluded that a large comet or asteroid has struck Earth and fired the rock from the ground into space where it collided with the surface of the Moon about 4 billion years ago. On the lunar surface, the scale is then mixed with other materials in one sample.
"This is an extraordinary find that helps paint a better picture of the early Earth and the bombings that have changed our planet during the dawn of life," said study co-author David Kring, a scientist at the Space Research Association of the University of Lunar and Planetary Institute.
