Overview
- New images from Hubble on Nov. 30 show a clear nucleus and bright coma as the interstellar object continues vigorous outgassing.
- ESA’s Juice navigation camera captured indications of two distinct tails—a plasma tail and a fainter dust tail—with the mission’s full science data due in February 2026.
- The closest approach to Earth is set for Dec. 19 at roughly 1.8 AU (about 270 million km), and agencies say the object poses no threat.
- Spanish researchers and an arXiv study propose cryovolcanism to explain observed jets and composition features, including reported metal-rich signatures.
- Harvard’s Avi Loeb cites ALMA reports of methanol and hydrogen cyanide with an unusually high methanol ratio and advances artificial‑origin and panspermia ideas, which other scientists and agencies characterize as unsubstantiated.
