How did scientists recreate cosmic dust in the lab?

Scientists recreated cosmic dust by using a vacuum to mimic space conditions and introducing gases found around dying stars, then energizing the mixture with high voltage to create a plasma.

What are CHON molecules found in cosmic dust?

CHON molecules are organic compounds of carbon, hydrogen, oxygen, and nitrogen, considered the chemical building blocks of life.

What is the significance of recreating cosmic dust?

Recreating cosmic dust helps scientists understand the origins of organic matter in meteorites and how life may have begun on Earth.

Lab Creates Star Dust to Unlock Life's Origins

Scientists have successfully recreated cosmic dust in a laboratory setting, a feat that promises to shed light on how life began on Earth. This simulated cosmic dust contains essential organic compounds, including CHON molecules, which are considered the chemical building blocks of life.

The research is crucial for understanding the origins of organic matter found in meteorites. Scientists are investigating whether these molecules formed on Earth, arrived from comets and asteroids, or were delivered during the solar system's formation.

To create the dust analogue, researchers used a vacuum to mimic space conditions and introduced gases found around dying stars. A high voltage energized the mixture, creating a plasma that yielded dust similar to that found in space. This method allows for the study of interstellar dust, which cannot be collected directly.
