Researchers at the University of Sydney have recreated cosmic dust in a laboratory.
The synthetic dust mimics particles formed around dying stars.
Cosmic dust contains organic molecules that may have seeded early life on Earth.
PhD researcher Linda Losurdo produced the dust using plasma inside a vacuum chamber.
The process replicated space conditions with carbon-rich gases and high voltage.
Scientists hope the work explains how meteorites gained organic material.
The findings appeared in the Astrophysical Journal.
