Scientists Detect Rare Type of Wood Alcohol in Space
Scientists have detected fully deuterated methanol, a rare type of wood alcohol, around the protostar IRAS4A2, which challenges existing chemical models for the formation of complex organic molecules in space. This discovery contributes to understanding how life's building blocks come together in the universe.
Why it matters
This discovery provides new insights into the chemical processes occurring in the early stages of star formation and the origins of organic molecules essential for life, potentially reshaping our understanding of astrobiology.
Today, the question of where life's building blocks come from is largely settled. Thanks to numerous discoveries in recent decades, scientists have confirmed that the organic molecules are found in space. In addition, recent research has also confirmed that amino acids can be found in Near-Earth Asteroids (NEAs) and proteins can form entirely on their own . Alas, some pieces of the puzzle are still missing, which are crucial to finding how these building blocks come together.
This includes Methanol (CH 3 OH), also known as wood alcohol, an organic molecule that plays an essential role in the formation of complex organic molecules in space. However, new research from the ALMA COMPASS Large program has detected fully deuterated methanol (aka. "heavy methanol") (CD 3 OD) around the protostar IRAS4A2. The abundance of this molecule around this very young star challenges current chemical models, which cannot reproduce the amount observed.
