Join us LIVE with Harvard astrophysicist Avi Loeb for the final verdict on the interstellar object 3I/ATLAS, the third confirmed visitor from beyond our solar system. We examine the newly proposed 14th anomaly: the remarkably rare alignment of 3I/ATLAS’s rotation axis within about 8 degrees of the sunward direction at distances greater than 5 AU, a configuration with a probability of less than about 0.5 percent if random.

This alignment has major implications for how we interpret the object’s anti-tail jet geometry, rotational dynamics, and overall physical behavior, adding to a growing list of anomalies that strain standard cometary explanations. Whether you are interested in jets, rotation periods, anti-tail physics, or what these observations imply about natural versus technological origins, this livestream offers a rigorous, evidence-driven deep dive. We will lay out the data, compare competing interpretations, and ask the central question: is 3I/ATLAS simply an unusual comet, or something fundamentally different?
