Scientists in 2017 detected the first sign of intelligent life outside Earth, according to a new book by Avi Loeb, a Harvard University professor.
The "rocky, cigar-shaped object with a somewhat reddish hue," was called "1I/2017 U1 'Oumuamua" by NASA.
"There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization," according to publisher Houghton Mifflin Harcourt.
An extraterrestrial object skimmed through space close to Earth in 2017, wrote a Harvard University astronomer, Avi Loeb, in a book to be published this month.
It was the first sign of intelligent life outside Earth, according to Loeb.
Scientists at a Hawaiian observatory saw "an object soaring through our inner solar system, moving so quickly that it could only have been from another star," according to the marketing summary for the Houghton Mifflin Harcourt book, "Extraterrestrial: The First Sign of Intelligent Life Beyond Earth."
The object wasn't a natural occurrence, but a bit of space junk ejected by another galaxy, according to Loeb, a professor of science with a doctorate in physics.
"There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization," according to HMH.
