Curtin University researchers discovered a rare presolar grain in an ancient meteorite from a star outside our solar system, revealing unique magnesium isotope ratios formed during a hydrogen-burning supernova.
Curtin University researchers found a rare dust particle in an ancient meteorite originating from a star outside our solar system. The presolar grain, analyzed using atom probe tomography, revealed unique magnesium isotope ratios, indicating it formed during a hydrogen-burning supernova. This discovery provides insights into the formation of stars and expands our understanding of the universe and cosmic events beyond our solar system.
