What if everything astronomers thought they knew about comets was wrong? On November 22, 2025, an amateur astronomer in Aguadilla, Puerto Rico, Efraín Morales Rivera, did more than just take a picture; he captured evidence that an interstellar visitor is rewriting the rulebook of celestial mechanics.
The object, known as 3I/ATLAS, is only the third confirmed interstellar visitor to our solar system—discovered by the NASA-funded ATLAS survey telescope in Chile on July 1, 2025.
