Interstellar objects come from beyond our solar system and pass through it as they travel through space. ʻOumuamua and 3I/ATLAS are two such objects discussed on this site. Studying them may reveal more about other planetary systems and the material between the stars.
Public interest in these objects also extends to the possibility that they have artificial origins. Astrophysicist Avi Loeb is among those who have discussed this hypothesis, but debate over it is not proof. Here you’ll find interviews about ʻOumuamua and 3I/ATLAS, scientific research, and the interpretations proposed for them.
