Loeb research paper links 3I/ATLAS non-gravitational acceleration to symmetric three-jet system

On 16 April 2026 Avi Loeb and collaborators released analysis attributing the previously unexplained non-gravitational acceleration of interstellar object 3I/ATLAS to a symmetric system of three jets observed during its perihelion approach. The Hubble Space Telescope imaged the object on 10 April 2026 at roughly 6.7 astronomical units from the Sun. 3I/ATLAS, discovered in July 2025 and the third confirmed interstellar visitor after 1I/Oumuamua and 2I/Borisov, displayed brightness, jet symmetry and outgassing patterns that Loeb has publicly catalogued as twenty-two anomalies. The April paper proposes that the three-jet geometry can account for the directional thrust without invoking artificial propulsion, while leaving open the broader anomaly catalogue that drives Loeb's ongoing argument for a peer-reviewed scientific posture toward unexplained phenomena.
