NASA finds ribose and glucose reported

NASA did not announce this finding on May 21, 2026. NASA published the result on Dec. 2, 2025, saying scientists analyzing samples from asteroid Bennu had found ribose and, for the first time in an extraterrestrial sample, glucose. The material came from NASA’s OSIRIS-REx sample-return mission, which collected rocks and dust from Bennu in 2020 and delivered them to Earth on Sept. 24, 2023. (nasa.gov) The discovery was reported by a Japanese-U.S. research team led by Yoshihiro Furukawa of Tohoku University and described by NASA as part of a broader set of Bennu results published in Nature Geoscience and Nature Astronomy. (nasa.gov) Social posts circulating in May 2026 appear to be resurfacing that earlier research rather than pointing to a new NASA release this week. ### Which asteroid sample are people talking about? Bennu is the near-Earth asteroid sampled by NASA’s OSIRIS-REx spacecraft on Oct. 20, 2020. NASA says OSIRIS-REx is the first U.S. mission to collect a sample from an asteroid, and the return capsule landed at the Utah Test and Training Range on Sept. 24, 2023. (nasa.gov) The Bennu material matters to researchers because it was collected in space and returned under controlled conditions. NASA said that makes it a more pristine record of early solar system chemistry than meteorites that fell to Earth and were exposed to terrestrial contamination. ### What exactly did scientists find in the Bennu material? (nasa.gov) NASA said Furukawa’s team identified ribose, a five-carbon sugar, and glucose, a six-carbon sugar, in the Bennu samples. NASA described glucose as a first in an extraterrestrial sample and said the sugars were found alongside other previously reported organic compounds in Bennu material. (science.nasa.gov) The earlier Bennu papers, published on Jan. 29, 2025, had already reported amino acids, ammonia, formaldehyde and all five nucleobases used by life on Earth in DNA and RNA. NASA said those findings, combined with the later sugar result, expand the inventory of biologically relevant molecules identified in the asteroid sample. (nasa.gov) ### Does this mean NASA found life? NASA said the answer is no. Its Dec. 2, 2025 write-up states that the sugars are “not evidence of life,” even though they add to the list of molecules that biochemistry on Earth uses. Nicky Fox, NASA’s associate administrator for the Science Mission Directorate, said in the agency’s Jan. 29, 2025 release that the findings do not show life itself but suggest that conditions necessary for life’s emergence were widespread across the early solar system. (nasa.gov) ### Why are ribose and glucose getting so much attention? Ribose is central to RNA. (nasa.gov) NASA said ribose forms part of RNA’s sugar-phosphate backbone, and Furukawa said the presence of ribose means Bennu now contains all the components needed to form RNA, because nucleobases and phosphates had already been identified. (nasa.gov) NASA also said researchers did not find deoxyribose in the Bennu sample. The agency said scientists think the presence of ribose and absence of deoxyribose support the “RNA world” hypothesis, which holds that early life may have relied on RNA before DNA and proteins took on their present roles. (nasa.gov) ### Does this prove panspermia? NASA’s language is narrower than some social-media posts. The agency said the Bennu chemistry shows that building blocks of biological molecules were widespread through the solar system and that asteroids may have delivered precursor ingredients to early Earth. (nasa.gov) That is not the same as proving panspermia, which generally refers to life, or its seeds, spreading between worlds. The Bennu papers and NASA releases cited here describe prebiotic ingredients and possible delivery pathways, not living organisms. ### What comes next in the Bennu research? (nasa.gov) NASA says Bennu sample analysis is ongoing. The OSIRIS-REx mission page lists the sugar discovery among the latest results and says the returned material continues to be studied for clues about the early solar system and the origins of life. OSIRIS-APEX, the renamed spacecraft after sample return, is now headed to asteroid Apophis for a planned encounter in 2029, while laboratories continue to publish new Bennu analyses from the material returned in 2023.
