NASA Sets Nov. 19 Briefing to Unveil New 3I/ATLAS Images as Interstellar Comet Reappears

The event will synthesize spacecraft and telescope measurements to deliver the clearest picture yet of the rare interstellar visitor’s behavior and route.

Overview

  • NASA will stream the briefing at 3 p.m. ET on Nov. 19 from Goddard via NASA+, the agency website, YouTube and Amazon Prime, featuring senior science leaders.
  • 3I/ATLAS poses no threat to Earth, will pass at roughly 270–273 million kilometers on Dec. 19, and previously flew about 30 million kilometers from Mars in early October.
  • Orbit solutions show a hyperbolic path out of the Solar System with a projected pass near Jupiter in March 2026 after its Oct. 29 perihelion.
  • ESA and U.S. teams combined data to sharpen tracking, with ExoMars TGO improving position predictions tenfold and JUICE observations in progress with results expected in February 2026.
  • Observations reveal a tear-shaped dust coma, active jets and relatively high CO2 compared with H2O, while claims of an artificial origin have been rejected by NASA, ESA and independent astronomers.
