Asteroids are rocky objects that orbit around the sun and are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, which vary in size from hundreds of kilometers to several meters in width. This is the definition of an asteroid, but they are also the witnesses of the history of the universe. But if we have to talk about asteroids, none has attracted so much attention as Oumuamua, a mysterious interstellar object in the shape of a cigar that sailed past the Earth at 156,428 km / h in October of last year.
On October 19, 2017, the Pan-STARRS-1 telescope, located in Hawaii, detected the asteroid Oumuamua on October 19 and was observed 34 times in the following week. He was baptized as Oumuamua, which in Hawaiian means the messenger from afar who arrives first, and passed close to the Earth at approximately 85 times the distance to the moon. The astronomers were completely bewildered since it was the first interstellar object seen in our solar system. At first it was thought that the mysterious object could be a comet, however, it did not show any expected behavior of a celestial body, like a tail of ice particles and dust.
It was estimated that Oumuamua was up to 400 meters long and 10 times as long as it was wide. These confusing data caused all kinds of hypotheses in the scientific community, including the researchers of Breakthrough Listen, a program funded by the late physicist Stephen Hawking, announced that they found no evidence that it was of extraterrestrial origin . However, now a recent study by researchers at Harvard University has suggested that the interstellar visitor Oumuamua could be an alien probe.
Confirmed: Oumuamua is of extraterrestrial origin
According to a recent study, the mysterious asteroid Oumuamua could be a gigantic extraterrestrial solar sail sent to look for signs of life. Astronomers at the Harvard-Smithsonian astrophysics center (CfA) analyzed the strange cigar shape of the object, the unexpected increase in speed and change in trajectory as it passed through the inner solar system last year. They have come to the conclusion that the strange asteroid could be a luminous candle of artificial origin.
