Scientists scrambled to observe the disapproved object before it disappeared, moving at a speed of 196,000 miles per hour, and their observations raised more questions than answers about the “audible ball” as scientists dubbed it.
Now, the latest research suggests that it is a Pluto-like piece of another solar system.
After the exploration, “the object was dubbed ‘Omuamua, Hawaiian’, a messenger coming from the distant past.” Initially, astronomers assumed it would be a comet.
But the dry, rocky red, elongated cigar-shaped object object, as thick as a three-story building and half the length of a city block, had no cometary tail, and could not explain its messy motion. And a debate has arisen over whether this is an international planet.
And, of course, there was speculation that ‘Omuamua was a form of alien investigation.
“In many ways, Omuamua looked like a comet, but the mystery surrounding its nature was strange in many ways, and speculation about what it was spread,” said Deshe, a professor at ASU.
Links to rocket impact
‘Omuamua differs from comets in many ways, including the fact that its velocity was low as it entered our solar system. If it had been traveling between interstellar stars for a billion years as a comet, it would have had more momentum.
Its shape was flattened like a pancake, unlike comets like the Cometic Snowballs. The Object object gained considerable momentum, known as the “rocket effect”, when comets evaporate more than they feel when their ice faces the sun.
The researchers wondered, ‘Omuamua was made of ice with various compositions, allowing them to calculate how quickly ice would turn to gas with a bezel zipped by the sun. This allowed Dashek and Jackson to determine the mass, shape and rocket effect and to assess how reflective the figures are.
“We realized that a portion of the ice would be more reflective than people think, which means it could be smaller. After the same rocket impact, ‘Omuamua will have a greater push than the comet normally feels.’
In our solar system, Pluto and Saturn’s moon Titan are mostly covered with nitrogen ice. If a large object is made up mostly of nitrogen ice, it is possible that a solid portion of it may have been scattered from a planet like Pluto after being affected by other planetary systems.
A similar phenomenon has occurred in our own solar system, including objects in Pluto and the icy Kuiper belt. This distant belt of objects on the edge of our solar system once had more mass than that.
When Neptune migrated to the outer solar system billions of years ago, it disrupted the orbits of these objects that remained from the formation of the solar system. Thousands of objects, like Pluto, covered with nitrogen ice, collided with each other.
If it could happen in our own solar system, the same event could probably happen in another solar system, meaning that “Omuamua could be the first specimen of an exoplanet born around another star to be brought to Earth,” the authors wrote. . Learning.
Jacques, a research scientist and research fellow at ASU, also said in a statement that it was knocked off the surface about half a billion years ago and thrown out of its original system.
“It also explains the unusual shape of the omeuamua made up of frozen nitrogen. As the outer layers of nitrogen ice evaporated, the body shape would gradually become more flat, as the outer layers of soap bar were removed. By use.”
The researchers estimated that Omuamua lost 95% of its mass due to its collision with our Sun.
Alien speculation
Theories by Avi Loeb, a professor of science at Harvard University, say that ‘Omuamua is an alien object or part of technology, and that the new book is Extraterrestrial: The First Sign of Intelligent Life Bind Earth. .
‘There is no evidence to prove that Omuamua is an alien technology, the researchers of this study said, adding that it is natural that the first observed object from outside our solar system would bring aliens to mind.
“But in science it is important not to go over those findings,” Desh said. “It took two or three years to find a natural explanation – a piece of nitrogen ice – that matches everything we know about ‘Omuamua. It’s not that long in science, and very soon it is said that we are all natural revelations. It’s over. “
However, ‘Omuamua has been a unique way for scientists to study any scientific project outside our solar system. Understanding more about ‘Omuamua’, which disappeared from view in December 2017, can shed more light on the composition and composition of other planets.
“So far, we have no way of knowing if there are planets like Pluto in other solar systems, but now we have seen the amount of a pass through Earth,” Deshe said.
Future telescopes, like the Vera Rubin Observatory in Chile, will regularly survey the fullness of the sky as seen from the Southern Hemisphere, increasing our ability to see more international objects entering our solar system. The observatory will start in 2022.
“It is hoped that in a decade or so we will be able to obtain statistics on what types of substances pass through the solar system, and if parts of nitrogen ice are scarce or as common as we calculated,” Jackson said. “Either way, we should be able to learn a lot about other solar systems, and whether they’ve gone through the same kind of colliding history that we did.”
