Is Oumuamua an Extraterrestrial Object?
Oumuamua is the name given to an object observed in our solar system for the first time in 2017. It is the first known sighting of an object that came from outside of our solar system, arriving to our solar system from unknown origins in interstellar space. Likely an asteroid, certain scientists--notably Avi Loeb of MIT--believe that it cannot be ruled out that this object is a craft from an advanced civilization.
