Ancient Meteorite Unveils Secrets of Early Solar System
The oldest meteorite ever found, Erg Chech 002, dating back 4.6 billion years, challenges the accuracy of age calculations for meteorites. Australian researchers discovered that it contained more Aluminium-26 than other ancient stony meteorites of a similar age, suggesting that the isotope was not evenly distributed in the early solar system. This finding contradicts previous research and raises questions about the role of Aluminium-26 in planetary formation. The study emphasizes the need for a generalized approach to dating meteorites and planetary materials to improve accuracy and reliability.
