Astronomers Detect Raspberry Sugar Near Milky Way Centre

Astronomers have detected erythrulose, a type of sugar found in raspberries, in gas clouds near the centre of the Milky Way galaxy [1, 2].

The discovery is significant because it suggests that the fundamental chemical building blocks necessary for life may be more common in the universe than previously understood [1, 2]. By identifying these complex molecules in deep space, researchers can better trace how the chemistry of life began in the cosmos [2, 3].

Rebecca Allen, one of the astronomers involved in the discovery, said, "We have found erythrulose, a sugar that on Earth is found in raspberries and self‑tanning lotions, in gas clouds near the centre of our galaxy" ^[1].

The detection occurred within the interstellar gas clouds that surround the galactic core [1, 4]. These regions are often hubs of intense activity and star formation, making them primary targets for astronomers searching for organic compounds. The presence of such a molecule in these harsh environments indicates that sugar can survive or form in the space between stars ^[3].

Researchers believe this specific molecule may be a critical link in understanding prebiotic chemistry. A lead researcher said the sweet molecule could be a missing piece in the puzzle of how life’s chemistry began in the cosmos ^[2].

The finding adds to a growing body of evidence that organic molecules are not exclusive to planetary bodies like Earth. An astronomer quoted in The Star said that finding a sugar in interstellar space suggests that the ingredients for life are more widespread than previously thought ^[3].
