Mysterious asteroid spotted by NASA could be an alien spaceship looking for signs of Life on earth


On 19th of October 2017, A weirdly, cigar shaped asteroid was discovered by Haleakala Observatory, Hawaii. It was observed that this asteroid was of "Interstellar origin" which means that, it originated outside our solar system. It was named Oumuamua. Fast forward this week, Astronomers from the Harvard Smithsonian Centre for Astrophysics (CfA) have measured a … Continue reading Mysterious asteroid spotted by NASA could be an alien spaceship looking for signs of Life on earth
