In a groundbreaking discovery, scientists have identified a rare dust particle lodged within an ancient extraterrestrial meteorite, shedding new light on the origins of stars beyond our solar system. This remarkable finding, published in the prestigious Astrophysical Journal, is challenging current astrophysical models and providing insights into stellar environments that are not yet fully understood.
Unraveling the Dust Particle’s Secrets
The research team, led by Dr. Nicole Nevill of the Universities Space Research Association at LPI during her Ph.D. studies at Curtin University, analyzed the dust particle with unparalleled precision using atom probe tomography. This advanced technique allowed the team to delve into the atomic composition of the particle, revealing an extreme magnesium anomaly that can currently only be explained by a recently discovered type of star — a hydrogen-burning supernova.
