A Harvard professor believes that we were visited by aliens in 2017. According to Professor, a peculiar-shaped object entered our solar system several years ago. This interstellar object is named “Oumuamua”. It was first observed through Pan-STARRS telescope in Hawaii.
It was observed three years ago. The object traveled toward our solar system from Vega. Vega is a nearby star 25 light years away. According to some scientists, it was just another comet but professor Avi Leob dismisses that assumption.
