Overview

• An international team led by James R. A. Davenport released a preprint outlining four technosignature search categories for interstellar objects and urging that such checks be built into routine follow-ups as discovery rates rise.
• Multiple facilities, including Webb, Hubble and the Allen Telescope Array, have targeted 3I/ATLAS, and researchers report that available data remain most consistent with a natural origin.
• Gemini South imaging shows a faint tail pointing away from the Sun and an expanded coma, while separate reports cite CO₂-dominated outgassing with estimated rates near 130 kg/s for CO₂ and far lower for water and CO.
• A Daily Galaxy report says archival TESS imagery captured the object roughly two months before its official discovery, with a study under review indicating the longer arc refines trajectory modeling.
• Harvard astronomer Avi Loeb has speculated about a tiny precursor probe potentially reaching Mars and has urged HiRISE imaging, a claim that remains unconfirmed and is not widely accepted by the community.
