"Unveiling Secrets of Ancient Supernova Stardust in Meteorite"
A rare dust particle found in an ancient meteorite has been determined to be older than the Sun, with a composition indicating it originated from an unusual type of supernova. The grain's isotopic ratios suggest it was formed by a hydrogen-burning supernova, a rare type of Type II supernova. This discovery provides valuable insights into the formation of the Solar System and the types of stars that contributed to its composition.
