A PhD student in Sydney has produced cosmic dust from scratch by recreating a small piece of the universe inside a laboratory bottle. The experiment offers new clues about how some of the chemical ingredients associated with life could have developed before Earth even formed.
Linda Losurdo, a PhD candidate in materials and plasma physics in the School of Physics, combined nitrogen, carbon dioxide and acetylene to simulate the energetic conditions found near stars and supernova remnants.
She then exposed the gases to a powerful electrical charge. The process created carbon-rich dust resembling material that floats through interstellar space and is preserved inside comets, asteroids and meteorites.
The findings were published in The Astrophysical Journal of the American Astronomical Society.
