Researchers recreated cosmic dust in a Sydney lab to study how life’s building blocks reached Earth.
University of Sydney PhD candidate Linda Losurdo produced dust by mimicking dying stars.
Cosmic dust carries organic CHON molecules, essential to life’s chemistry.
Scientists debate whether these molecules formed on Earth or arrived via meteorites.
Losurdo used plasma and star-like gases inside a vacuum chamber.
The method reproduces dust with infrared signatures matching real space material.
Experts say the work could advance research into early life formation.
The study appeared in the Astrophysical Journal.
