SOHO spots water gushing from interstellar comet 3I/ATLAS after its Sun pass

Water Where There Should Be None Why Interstellar Object 3I/ATLAS Is Breaking The Comet Rulebook

KEY OBSERVATIONS Too far from the Sun to behave this way.Too active to be dismissed as noise.Too consistent to ignore. An object from another star system is active in deep space where comets are supposed to sleep. [USA HERALD] – When scientists measured water vapor coming from interstellar object 3I/ATLAS while it was still far beyond the Sun’s usual zone of influence, the result immediately raised red flags. At roughly three and a half times…

SOHO spots water gushing from interstellar comet 3I/ATLAS after its Sun pass

NEW YORK, January 4, 2026, 17:01 ET Scientists have measured water streaming from interstellar comet 3I/ATLAS after its late-October pass around the Sun, using a solar-monitoring spacecraft to estimate how fast the object was shedding ice into space.  Phys The timing matters because most early work on 3I/ATLAS focused on its approach, when sunlight was ramping up the comet’s activity. Post-perihelion data are harder to capture as objects fade an…
