Astronomers recently observed 3I/ATLAS, the third interstellar object recorded, entering the solar system. While the scientific consensus suggests it is a comet, Harvard's Avi Loeb speculates it might be of artificial origin. He refers to NASA's Hubble observations, which showed a glow indicating a coma but no cometary tail, suggesting dust evaporation. Loeb proposes two theories about the object's origin: it could be a fragment from a radioactive supernova or an engineered object, possibly more luminous than initially believed.
Astronomers observed 3I/ATLAS, an interstellar object approaching the solar system, with varying theories about its origin; Loeb posits it could be an engineered object.
The Hubble observations showed a coma surrounding 3I/ATLAS, but lacked a bright cometary tail, leading to Loeb's speculation about the object generating its own light.
