The Atacama Large Millimeter Array (ALMA) telescope in Chile has captured the largest image ever taken of the heart of our galaxy, illustrating a hidden and complex chemistry at a distance of 28,000 light-years from Earth. This groundbreaking image focuses on the Central Molecular Zone, a region characterized by extreme conditions and dense stellar and gas reservoirs. It highlights how this area comprises nearly 80% of our galaxy's dense gas, serving as a crucial site for star formation and cosmic processes.

The research, named the ALMA CMZ Exploratory Survey (ACES), provides astronomers with unprecedented insights into the intricate chemical interactions occurring within this dense galactic area. Scientists have detected a wide array of molecules, ranging from simple compounds like silicon monoxide to more complex organic molecules such as methanol, acetone, and ethanol. This extensive molecular catalog offers new possibilities for understanding the chemical complexity of the galaxy and the building blocks necessary for star and planet formation.

One of the most exciting findings of this survey is the rich chemistry that has been recorded, and the presence of dozens of different molecules indicates active and dynamic processes within this central galactic zone. The results not only enhance our understanding of the galactic center’s chemical landscape but also have broader implications for understanding the origins of life in the universe, showcasing how such complex molecules might contribute to the development of habitable environments.
