Scientists believe there is possibility that aliens are listening to us on Earth. Astronomers from program called Breakthrough Listen are excited about giant, mysterious space object that has passed close to our plant. Breakthrough Listen scientists search for evidence of civilizations beyond Earth. scientists work at University of Hawaii. They described object as 800-meter-long, 80-meter-wide, cigar-shaped rock. Some scientists believe rock has too many straight lines on it for it to be formed naturally. This suggests it could have been designed by some form of extra-terrestrial life. scientists have dubbed rock Oumuamua, which means 'first messenger' in Hawaiian language.

astronomers first spotted Oumuamua in October. It was travelling at great speed through solar system and passed Earth at about 85 times distance to the Moon. This is just hair's breadth relative to vast expanses of universe. Oumuamua is first object spotted in solar system that appears to originate from another star system. The astronomers say its high speed of over 300,000 kph suggests it is outside gravitational pull of the Sun and is instead travelling on its own path that originated in another galaxy. scientists said it was highly unlikely that Oumuamua was sign that aliens exist, but the huge rock and its journey was a unique event that possibly offered new secrets.
