Hubble and ESA’s Juice Capture Clearer Views of Interstellar Comet 3I/ATLAS Ahead of Dec. 19 Flyby

Unusual methanol and hydrogen cyanide readings elevate scientific interest, with full Juice datasets due in February.

Científicos descubrieron que el cometa 3I/ATLAS empezó un estado de actividad antes de aproximarse a la Tierra
Un científico de Harvard adivrtió que este objeto interestelar podría ser un artefacto alienígena.
Científicos descartan que se trate de un objeto artificial pues su comportamiento es consistente con un cometa natural
Pronto el cometa 3I/ATLAS estará en su punto más cercano a la tierra y las preguntas sobre este objeto interestelar continúan creciendo

Overview

  • New images from Hubble (Nov. 30) and a partial NavCam frame from ESA’s Juice show a bright coma and indications of two distinct tails.
  • 3I/ATLAS will pass about 1.8 AU from Earth on December 19—roughly 270 million kilometers—posing no threat according to NASA.
  • ALMA observations led by NASA astrochemist Martin Cordiner report unusually high methanol and hydrogen cyanide compared with typical solar‑system comets.
  • ESA says Juice used five instruments for a short observing campaign in early November, and higher‑resolution composition and particle data are expected to arrive on Earth in February 2026.
  • Harvard’s Avi Loeb has floated a possible artificial origin, but NASA officials say no technosignatures have been detected and characterize the object as a comet.
