Photo / SuppliedProfessor Avi Loeb, the former chair of astrophysics at Harvard University, believes an object that passed through our solar system had extraterrestrial origins - but his colleagues largely disagreed. In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. The object - dubbed "Oumuamua" - was pancake-shaped and as big as a football field. It had no tail so wasn't a comet and it was moving too quickly to be an asteroid. Professor Loeb lays out this controversial theory , which enraged some of his colleagues, in his new book Extraterrestrial.
