A Harvard professor named Avi Loeb, the chair of Harvard’s Department of Astronomy, believes the first sign we will get of an alien intelligence won’t be spacecraft. Rather he thinks the first sign we will get of extraterrestrial life will be the civilization’s trash. Loeb has a book being published on January 26 that lays out a case for why a bizarre asteroid that entered our solar system in 2017 was a piece of alien technology. The object he is talking about was the first known interstellar object to enter our solar system and traveled to our solar system from the direction of Vega. Vega is a star about 25 light-years, nearby in the cosmic scale. The object entered our solar system’s orbital plane on September 6,2017. By September 9, the object, known as Oumuamua, made its closest approach to the sun, and by the end of September and it traveled past Venus’s orbital distance.
