However, the results may not be enough to truly settle the debate on the Moon’s age, according to Richard Carlson, the director for the department of terrestrial magnetism at Carnegie Institution for Science.

While Carlson says Barboni and her team did solid work, he has a few concerns about the technique used to analyze the zircon, as well as some assumptions that were made in the study.

The giant impact would have created a massive ocean of liquid magma that eventually coalesced into the Earth and the Moon.

The chemical signatures of zircon allowed the scientists to estimate when the Moon’s solidification occurred — a key process that is often considered the beginning of the Moon’s life.

, involved breaking down the chemical components of a mineral within the lunar samples called zircon, according to lead study author Mélanie Barboni.
