The object known as 3I/ATLAS has stunned astronomers with twin jets that form straight, stable plumes over millions of kilometres, a phenomenon many say should be impossible given what we know about comet behaviour and physics.
In recent weeks, the interstellar comet currently traversing our solar system has behaved in ways that even veteran scientists find deeply puzzling. Harvard astrophysicist Avi Loeb says these anomalies may be telling us this object is far more unusual—and potentially risky—than we initially believed, potentially signalling that conventional, natural explanations are growing increasingly strained.
