Very High Credibility
Score 88 / 100 · Tier 1
The two-minute version
ESO reports that Very Large Telescope measurements of carbon and nitrogen isotope ratios in interstellar comet 3I/ATLAS indicate it formed in the outskirts of an ancient planetary system and may predate the Sun.
Why it matters
Isotopic composition data anchors 3I/ATLAS as a natural, very old object, pushing back against artificial-origin speculation. Watch how Loeb's council and SETI teams reconcile this with technosignature searches.
