High Credibility
Score 76 / 100 · Tier 1
The two-minute version
An arXiv preprint reports high-resolution VLT/ESPRESSO spectroscopic monitoring of interstellar comet 3I/ATLAS across its perihelion passage, tracking CN and forbidden oxygen emission.
Why it matters
Detailed spectroscopy is how the 3I/ATLAS composition debate gets settled empirically, away from the alien-probe talk. Watch for the peer-reviewed version and whether the chemistry looks ordinary or anomalous.
