Scientists have detected glycolaldehyde, a simple sugar, in a star-forming region of space, providing new clues about how life's building blocks may have formed. The discovery was made using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, focusing on a young star system called IRAS 16293-2422, about 400 light-years from Earth.
Glycolaldehyde is a key sugar that can react to form ribose, a component of RNA. This finding supports the theory that complex organic molecules, essential for life, can form in space and potentially be delivered to planets like early Earth via comets or meteorites.
The research, published in the journal 'Astronomy & Astrophysics' in 2022, was led by a team from the University of Copenhagen. They emphasized that this is the first time such a sugar has been found in a region where planets are forming, suggesting that the ingredients for life could be common throughout the universe.
While the discovery does not prove that life exists elsewhere, it shows that the chemical precursors necessary for life can arise in interstellar space. The team plans to continue searching for other complex molecules in similar star-forming regions.
