A research by American astronomers revealed that aliens have visited earth about three years back.
According to Abraham Lobe, professor of Harvard University and an astronomer, mysterious object that passed by earth may indeed be an alien spaceship, in 2017.
On 19th October 2017 an unidentified spaceship entered in the earth’s space which was named as ‘Oumuamua’, which means “a messenger that reaches out from the distant past”
Moreover, as per the research of Harvard University’s professors, the spaceship or alien technology might have been sent to earth to gather information about the planet.
The research also predicted that the spaceship travelled 196000 miles per hour.
