Astronomers Detect Largest Sulfur Molecule In Interstellar Space
Astronomers report detection of the ring-shaped molecule 2,5-cyclohexadiene-1-thione (C6H6S) in molecular cloud G+0.693–0.027, published in Nature Astronomy. They measured laboratory rotational spectra from thiophenol discharge products, then identified the molecule in IRAM 30m and Yebes 40m radio data near the Milky Way center, about 27,000 light-years away. The finding shows complex sulfur chemistry exists in starless clouds, linking interstellar chemistry with cometary materials.
Key Points
- 1Detects 2,5-cyclohexadiene-1-thione (C6H6S) in G+0.693–0.027 using IRAM and Yebes telescopes
- 2Demonstrates complex sulfur chemistry exists pre-star formation, bridging interstellar and cometary compositions
- 3Enables targeted laboratory spectroscopy and astronomical searches for larger sulfur-bearing molecules with known fingerprints
Scoring Rationale
High novelty and reliable Nature Astronomy validation, but findings mainly affect astrochemistry, not core AI/ML/data-science topics.
