    "body_text": "Astronomers have identified erythrulose, a four-carbon sugar, in interstellar material, Nature reports. The detection extends the inventory of relatively complex organic molecules known to form outside the Solar System and gives origin-of-life chemistry another plausible ingredient to track. A molecule's presence in space does not show that life formed there or that it reached early Earth. The new result is a spectroscopic identification and a chemical-pathway clue, not biological evidence.",
