Sydney Scientists Recreate Cosmic Dust to Probe Life’s Origins

Researchers say cosmic dust may explain how organic matter reached early Earth.
Linda Losurdo created cosmic dust from scratch at the University of Sydney.
The lab-made dust mimics particles released by dying stars.
Cosmic dust contains CHON molecules, the chemical building blocks of life.
Scientists debate whether these molecules formed on Earth or arrived from space.
Losurdo recreated space conditions using a vacuum, gas mixtures, and high-voltage plasma.
The method lets researchers trace how meteorites gained organic material.
Experts say the work could help model early life formation on other planets.
