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.
The study entitled ‘Could the solar radiation pressure explain the peculiar acceleration of Oumuamua?’, Has been carried out by Shmuel Bialy, postdoctoral researcher of the Institute of Theory and Computation (ITC) of CfA, Professor Abraham Loeb, director of ITC, and science professor Frank B. Baird Jr. of Harvard University and chairman of the Breakthrough Starshot Advisory Committee.
The researchers say that the strange acceleration could be the result of solar radiation pushing a giant solar sail . They explained that a candle only a fraction of a millimeter thick (0.3-0.9 mm) would be enough for a sheet of solid material to survive the journey across the galaxy. Solar sails with similar dimensions have been designed and built by humans, including the IKAROS project, a space probe launched by the Japanese space agency in 2010, and the Breakthrough Starshot project.
“Considering an artificial origin, one possibility is that ‘Oumuamua is a luminous candle, floating in interstellar space like a rubble of an advanced technological team,” the researchers wrote.
“Alternatively, another theory is that Oumuamua may be a fully operational probe intentionally sent to the vicinity of the Earth by an alien civilization,” they added.
Another option, which would explain the lack of any type of signal, could mean that the giant object is actually the remains of an alien spacecraft . Professor Loeb wrote in Scientific American that Oumuamua could be the first known case of an artificial relic that entered our Solar System from interstellar space.
“This opportunity establishes a potential basis for a new frontier of space archeology, namely, the study of the relics of past civilizations in space, ” Loeb explained in the article published last September. “Finding evidence of space debris of artificial origin would provide an affirmative answer to the old question ‘Are we alone? ‘ This would have a dramatic impact on our culture and would add a new cosmic perspective to the importance of human activity. ”
Loeb told the astronomy portal Universe Today that Oumuamua could be an active piece of alien technology that came to explore our Solar System, in the same way, that we hope to explore Alpha Centauri using Starshot and similar technologies.
“The alternative is to imagine that Oumuamua was on a reconnaissance mission, ” Loeb said. “The reason why I contemplate the possibility of recognition is that the assumption that Oumumua followed a random orbit that requires the production of ~ 1015 of objects per star in our galaxy. This abundance is up to one hundred million times more than what is expected from the Solar System, according to a calculation we made in 2009. A surprisingly high superabundance, unless Oumuamua is a specific investigation on a reconnaissance mission and is not a piece of evidence. a random population of objects. “
No doubt it is an incredible revelation, that scientists recognize the existence of intelligent extraterrestrial life somewhere in the universe. And as expected, the numbers believers and theoreticians of the conspiracy consider this finding as an authentic proof that the aliens send exploration ships to Earth to prepare an invasion of our planet. Then Oumuamua would have detected our presence without us doing anything.
Do you think that Oumuamua is an extraterrestrial space probe, the remains of a ship of an advanced civilization or is it the beginning of alien invasion?
