Scientists say cosmic dust may hold clues to how life began on Earth.
At the University of Sydney, researcher Linda Losurdo has recreated cosmic dust in a laboratory.
Cosmic dust forms around dying stars and contains organic molecules linked to life.
Meteorites carrying this dust may have delivered key ingredients to early Earth.
Losurdo simulated space conditions using a vacuum, gas mixtures, and high-voltage plasma.
The artificial dust matches infrared signatures seen in real interstellar particles.
Experts say the work could advance research into early life and planetary formation.
