Rare Presolar Particle from Hydrogen-Burning Supernova Discovered

Using advanced atom probe tomography, researchers have uncovered a dust particle in a meteorite that offers unprecedented insights into the universe's history.

A rare dust particle found in an Antarctic meteorite has been identified as presolar, predating the Sun and originating from a hydrogen-burning supernova.
The discovery was made using atom probe tomography, revealing the highest magnesium isotopic ratio ever found, suggesting its formation in a recently discovered type of supernova.
The presolar grain's unique chemical signature provides insights into the life of its parent star, offering a glimpse into cosmic events beyond our solar system.
This groundbreaking research, led by Dr. Nicole Nevill and her team, pushes the boundaries of analytical techniques and astrophysical models.
The findings not only enhance our understanding of the universe but also highlight the importance of rare particles in meteorites for gaining insights into cosmic events.
