Cosmic candy, anyone?
Sugars, Gum, Stardust Found in NASA's Asteroid Bennu Samples
Cosmic candy and 'space gum' spark sneeze fears, bubblegum jokes, and origin‑of‑life brawls
TLDR: NASA’s Bennu samples contain life-related sugars like ribose and glucose plus a weird nitrogen‑rich ‘space gum’ and stardust, hinting early solar system chemistry made life’s ingredients. Commenters swung between bubblegum memes, 'someone sneezed?' contamination fears, and existential debates about whether comets or pure chance seeded our planet.
NASA cracked open asteroid Bennu’s “goodie bag” and found life-related sugars—ribose (linked to RNA) and glucose (life’s go-to energy source)—plus a mysterious “space gum” rich in nitrogen and oxygen, and a surprising haul of supernova stardust. Scientists stress this isn’t life, but it’s a juicy clue: all the key pieces for RNA have now turned up in Bennu’s pristine samples from OSIRIS‑REx, supporting the idea that early life might have run on RNA before DNA ever showed up.
But the real fireworks are in the comments. The word “gum” sent the thread into a sugar rush of memes—“extraterrestrial bubblegum” is now canon—and the community is divided. One camp is wide‑eyed at “cosmic candy” raining from space; another instantly went CSI: Cleanroom, asking whether anyone “sneezed” in the sample and demanding chain‑of‑custody receipts. Then the existentialists rolled in: if comets seeded Earth, what seeded the comets—is it just “chance with extra steps”? Pedants even nitpicked the headline’s quotation marks. Meanwhile, skeptics and stargazers tussled over contamination vs. “trust the lab,” while fascinated readers latched onto the RNA world angle: no deoxyribose (the DNA sugar) found, but ribose was—potentially a hint about how life might have started. Science brought the facts; the comments brought the drama.
Key Points
- •Three peer-reviewed papers report new results from NASA’s OSIRIS-REx Bennu samples in Nature Geoscience and Nature Astronomy.
- •Ribose and, for the first time in an extraterrestrial sample, glucose were detected; deoxyribose was not found.
- •All five nucleobases and phosphates had previously been identified in Bennu material, meaning all components for RNA are present.
- •A previously unseen, nitrogen- and oxygen-rich, gum-like polymeric material was discovered, likely formed as Bennu’s parent body warmed.
- •An unexpectedly high abundance of supernova-derived dust was identified in the samples.
