The mystery of Omuwa, the first interstellar object ever discovered in our solar system, received a new twist, unexpected, and someone you did not expect – NASA.
In a new study published in astronomy, The government space agency reveals that when it looked at the interstellar object in November with its Spitzer Space Telescope, it came with nothing.
"Omamura was too weak for Spitzer to recognize when it looked more than two months after the nearest event of the object [sic]To Earth in early September, "NASA said in a statement accompanying the study. "However," without discovery "sets a new limit on how large a strange object can be."
A hysterical interstellar object can be a "leitseil"
NASA also noted that Oumuamua, Hawaii's name for "pathfinder" or "scout", was unusually bright, perhaps up to 10 times more reflective of the comets that are normally found in our solar system.
"But Ammoua has made its surface fresh through such" outgassing "when it has made a very close approach to its surface," NASA added in a statement. Our sun, just over five weeks before it was discovered. In addition to sweeping dust and dirt, some of the released gas may have covered the surface of "Umuwa with reflective coat of ice and snow – a phenomenon observed in comets in our solar system."
The study's summary only adds further intrigue to why NASA never saw it when it pointed to its telescope at the object in November.
"Both our size and our outer limits are important because" the path of Omuwama shows a gravitational acceleration that is sensitive to size and mass, and probably caused by emissions, "the study concludes." We suggest that Oumuamua may experience low-emission Emissions and emission emissions that produced a fresh, bright, ice coat. "
NASA added that it limits the amount of carbon monoxide and carbon carbon expected to come from the object, but added that other species of gas – probably "H2O" – caused the observed "non-gravity acceleration."
Oumuamua was discovered in October 2017 by Canadian physicist and astronomer Robert Weryk.
A strange interstellar object is not an alien probe, says an astronomer who exposed IT
Due to different degrees of brightness emanating from Omuamu's surface, NASA suggests that it is "very elongated and probably less likely (2,600 feet or 800 meters) anyway in its longest dimension."
The conspiracy of what Ummamua is or has not picked up significantly in recent weeks, especially as some researchers have a theory that this could be an object from extraterrestrial civilization.
A study from the Harvard-Smithsonian Center for Astrophysics says the goal could be "lights of artificial origin" sent from another civilization. "Given the artificial origin, one possibility is that Omamura is lighting lights, floating in interstellar space like waste from advanced technological equipment," wrote Shmuel Biyali and Avraham Loeb in the article.
Warwick called this idea simple and simple "wild speculation," although he noted that the speed of the object was unusual.
"There is maximum speed you can be driving to be chained to gravity by the sun," said Werkk Kennedy of CBC originator in an interview. "When we first saw this object, it traveled faster than that, so we know for a fact that it is outside our solar system, we decided it was a comet that had some outgassing that did not look from the ground, so it did not seem to be a comet."
He continued: "(Harvard researchers) decided to focus on another aspect of it, because it is a foreign spacecraft and it has a type of solar sail and this type causes a non-gravity trajectory, but we really believe that this is not true based on the data we received."
In an e-mail to "Fox News," Libya said that Bailey's newspaper "is trying to explain the excess power" that was working on Oumwamwe, when he was observed and Warwick's reaction "shows prejudice."
Comets and asteroids can move life all over the galaxy,
"Our paper follows the standard scientific methodology: Anomaly is observed in the data, the standard explanation does not explain it, and therefore an alternative interpretation is offered," Loeb wrote in an e-mail, "I encourage everyone with a better explanation to write an article about it and publish it. Any incorrect interpretation can be ruled out when additional data will be released on `Oumuamua or other members of its population in the future. The kind of response you quoted shows prejudice. "
NASA was robust because it is a "metallic or rocky object" and is probably a comet.
So can we ever learn more about why it was so bright or why it has extraordinary acceleration?
An InterStellar Visitor & Omaha He never left the house,
"Normally, if we get a measurement from a comet that's pretty weird, we'll measure it again until we understand what we're seeing," said David Pernoch, a NASA research fellow. We probably know about it the way we're going to know. "
