Scientists have detected eritruroza, a sugar found in raspberries and skincare products, in an interstellar cloud near the Milky Way’s center, marking the first time a sugar has been identified in space. The discovery, published in *Nature Astronomy*, suggests organic molecules essential to life may form in cold cosmic environments, potentially reshaping theories about life’s origins.
For the first time, astronomers have identified a sugar—eritruroza—in the vast expanse of interstellar space, offering a tantalizing glimpse into how life’s building blocks might have formed beyond Earth. The discovery, made in a molecular cloud near the Milky Way’s center, was reported by researchers using radio telescopes in Spain, with results published in *Nature Astronomy* on July 16, 2026.
How the Sugar Was Found
Researchers analyzed the molecular cloud G+0.693-0.027, located near the galactic center, using the 40-meter telescope in Javalambre and the 30-meter IRAM telescope. By comparing spectral data from the cloud to lab-generated samples, they detected eritruroza—a four-carbon sugar—floating in the interstellar medium. We weren’t expecting to find this, said Dr. Izaskun Himenez-Sera, a researcher at Spain’s Astrobiology Center, in an interview with *Danas*. It was a surprise.
The sugar’s presence was confirmed through its unique spectral signature, which matched lab experiments. Eritruroza, commonly used in skincare products and found in small amounts in raspberries, is not directly essential for life but can transform into molecules critical for RNA and DNA formation. It’s a stepping stone, explained Himenez-Sera. This shows that complex organic molecules can form in space without the need for extraterrestrial civilizations.
Implications for Life’s Origins
The discovery challenges previous assumptions about how life’s ingredients might have arrived on Earth. While meteorites and comets are often cited as potential carriers of organic material, this finding suggests such molecules could form independently in space. This adds weight to the idea that the basic chemicals of life were already present in the early solar system, said Professor Jošihiro Furukava of Japan’s Tohoku University, who previously studied sugars on asteroid Benu.
Eritruroza’s detection also aligns with earlier findings of simpler sugars in meteorites and on asteroid Benu. In 2024, NASA’s OSIRIS-REx mission revealed sugars like ribose and glucose in Benu’s samples, hinting that organic molecules could have been delivered to Earth via space rocks. However, this new study is the first to directly observe a sugar in interstellar space, rather than in meteorites or asteroids.
A Cosmic Chemical Playground
The findings highlight the Milky Way’s role as a “chemical factory,” where complex molecules form in the cold, dark regions between stars. Eritruroza’s creation likely involves reactions on microscopic dust particles, where organic compounds like glycolaldehyde and ethylene glycol combine at temperatures as low as -250°C. This is an example of material drifting freely across the galaxy, said astrobiologist Erika Hamden of the University of Arizona, who was not involved in the study. It suggests that the ingredients for life are more widespread than we thought.
The research also underscores the potential for life to emerge elsewhere in the universe. If these sugars are common, it opens the door to life developing on other planets, Hamden said. It’s not just about Earth—it’s about the entire cosmos.
What’s Next for the Research?
Scientists now aim to search for more complex sugars and organic molecules in space, using advanced telescopes like the James Webb Space Telescope. We want to see how these molecules evolve and whether they can form even more complex structures, said Himenez-Sera. Future studies may also explore how these cosmic ingredients interact with planetary environments, shedding light on the conditions that could foster life.
The discovery has already sparked interest in the scientific community. This is a landmark, said Dr. Himenez-Sera. It changes how we think about the origins of life. As researchers continue to probe the universe’s chemical richness, the question of whether life is unique to Earth may soon have a very different answer.
