Hubble and NASA probe track interstellar comet 3I/ATLAS, revealing jets, an anti‑tail and spin
On Jan. 22, 2026 Hubble observed interstellar comet 3I/ATLAS nearly aligned with the Sun–Earth line, exposing unprecedented jet structures and an extended anti‑tail. Simultaneously a NASA exoplanet probe tracked the visitor to measure its spin and activity as it departs the inner solar system.
