Researchers say recreating cosmic dust could reveal how life’s building blocks reached Earth.
At the University of Sydney, PhD candidate Linda Losurdo has produced cosmic dust from scratch in a laboratory.
Cosmic dust forms around dying stars and contains CHON molecules essential for life.
Scientists debate whether these molecules formed on Earth or arrived via meteorites.
Losurdo recreated space conditions using a vacuum, gases, and high-voltage plasma.
The artificial dust matches infrared signatures seen in real meteorites.
Experts say the method could help explain how organic matter formed across the universe.
