"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.

"Newly Discovered Supernova Remnant Unveiled by Astronomers"

Astronomers from Curtin University and other institutions have discovered a new supernova remnant (SNR) named G321.3-3.9, located 3,300 light years away. The elliptical SNR is estimated to be a few thousand years old and was confirmed using radio and X-ray data. The SNR's distance, diameter, and age were estimated, but uncertainties remain due to limited data. Further observations are planned to search for a pulsar association, which could provide more accurate measurements of the SNR's properties.

"Revealing the Enigma: Unraveling Earth's Deepest Gemstone"

Scientists from Curtin University have discovered the missing ingredient in the formation of pink diamonds by studying the Argyle volcano in Western Australia. In addition to deep carbon and tectonic plate collisions, the stretching of continents during continental break-ups creates pathways for diamond-bearing magma to rise to the Earth's surface. The researchers found that the stretching of landmasses created gaps in the Earth's crust, allowing diamond-carrying magma to emerge. This discovery could aid in the search for new pink diamond deposits worldwide. The Argyle volcano, which has produced over 90% of the world's pink diamonds, is situated at the suture of two ancient continents, making it a unique source of these rare gems.
