Science confirms: Earth has more than one moon

Hungarian astronomers have proven the presence of two "pseudo satellites" in circulation around the world. These dust blasts were discovered only in the sixties, but are so difficult to discover that researchers have discussed their existence since then. The findings can be used to determine where to put satellites in the future and will need to be considered when performing interplanetary space missions. After more than fifty years of stargazing, debate and controversy, scientists have confirmed the existence of two "moons" or "pseudo-satellites" made of dust that circles around the globe. Despite the rapid use of mathematics, they also argue that the location of these dust sheds gives them some unique features.
Where are they? G. HorváthArtist's impression of the Kordylewski cloud in the night sky (with its brightness intensified) at the observations. The Kordylewski clouds are two dust sheds first observed by Polish astronomer Kazimierz Kordylewski in 1961. They are located at two of Lagrange points in the earth's orbit. These points are places where the gravity of two objects, such as the earth and the moon or a planet and the sun, corresponds to the centripetal required to track the objects while they are in the same relative position. There are five of these spots between the earth and the moon. The clouds rest at what are called the four and five, forming a triangle with the clouds and the earth in the three corners. The clouds are huge and take up the same space in the night sky as twenty moon discs. covers an area of ​​45,000 miles. They are about 250,000 miles away, about the same distance from us as the moon. They consist entirely of vacuum cleaners that reflect the sun's light so weakly most astronauts who were looking for them could not see them at all. The clouds themselves are probably ancient, but the model that the researchers created to learn about them suggests that the individual dust particles made up of them can be blown away by sunshine and replaced by the dust from other cosmic sources like the tails of the comedy. This means that the clouds barely move but change forever.
How did they discover this? J. Slíz-Balogh "On this image, the central region of the Kordylewski dust cloud is visible (light red pixels). The straight lines are traces of satellites." In his study published in the monthly reports of the Royal Astronomical Society, the Hungarian astronomers Judit described Slíz-Balogh, András Barta and Gábor Horváth how they could find the dust rinses using polarized lenses. Since the clouds were expected to polarize the light bouncing by them, by configuring telescopes to look for this type of light, the clouds were much easier to detect. What the researchers observed, polarized light in patterns that stretched beyond the telescope's view were in line with the predictions of their mathematical model and excluded other possible sources.
Why do we learn right now? J. Slíz-Balogh "Mosaic pattern of polarization angle around the L5 point of the Earth's M5 system (white point). The five rectangular windows correspond to the image-forming telescope as the patterns in the Kordylewski cloud were measured." The objects, which are dust clouds, are very weak and hard to see. While Kordylewski observed them in 1961, other astronomers have looked there and received mixed reports in the following decades. This discouraged many astronomers from joining the search, as the co-author of the study Judit Slíz-Balogh explained: "The Kordylewski clouds are two of the toughest objects to find, and although they are as close to the earth as the moon is largely overlooked by researchers in Astronomy. It's exciting to confirm that our planet has dusty pseudo satellites in circulation beside our lunar children. "
Will this have any impact on space
trips? Lagrange points have been developed as excellent locations for a space station or satellites like the James Webb Telescope to put in circulation, as they would require some fuel to stay in place. Knowing a massive dust cloud that can damage sensitive equipment already there can save money and live in the future. While we only know about the clouds in Lagrange scores four and five right now, the author of the study suggests that there may be more on other points. Although the discovery of a pair of dust clouds may not seem all that impressive, it is the result of half a century of astronomical and mathematical work and reminds us that wonders are still hidden in our cosmic backyard. While you may never have to worry about these clouds again, there's nothing wrong with looking at the sky with the wonders of the strange and amazing things we can discover.
