A team of astronomers has made a groundbreaking discovery of a natural sugar called "erythritol" in a cloud of dust and gas between the stars near the center of the Milky Way galaxy. This sugar is one of the fundamental compounds essential for life, playing a role in energy production and the construction of biological structures. It is also an important component of RNA and DNA molecules. It is believed that this compound can form from simpler molecules on dust grains in space, supporting the hypothesis that the organic compounds vital for life may have already been created in the space between stars before the formation of stars and planets. The presence of erythritol was detected using two radio telescopes. This discovery opens the door to searching for more complex sugars, such as ribose, which is a key component of DNA. Estimates suggest that between 500,000 and 50 million metric tons of this sugar may have been delivered to Earth during the early stages of planetary formation, strengthening the possibility that the organic origins of life may have arisen in space before reaching Earth.
