"Unveiling Secrets of Ancient Supernova Stardust in Meteorites"

Researchers at Curtin University have discovered a rare dust particle in an ancient meteorite, formed by a star other than our sun, using a technique called atom probe tomography. The particle has an exceptionally high isotopic ratio of magnesium, indicating formation in a recently discovered type of star—a hydrogen burning supernova. This discovery, detailed in the Astrophysical Journal, provides insights into cosmic events beyond our solar system and pushes the boundaries of both analytical techniques and astrophysical models.
