In the 1960s, astronomers observed two places that seemed to be in orbit around the Earth, such as the MoonSince then, many debates have faced different hypotheses, debates and speculation. Now a group of Hungarian scientists have discovered that they are two hidden moons made entirely of dust that spins around the planet and can influence future plans for exploring the universe.
According to a new study published in the Monthly Magazine of the Royal Academy of Astronomy, large amounts of dust 400,000 kilometers from Earth, right behind the most famous satellite about 385,000 kilometers away. They are huge: they are about 100,000 to 70,000 kilometers.

Although they were observed for the first time in 1961, when a Polish astronomer Kazimierz Kordylewskiwhose name has since been identified, have always been so small due to their composition that the experts have not reached agreement on their nature.
"The Kordylewski clouds are two of the toughest objects,, said National Geographic Judit Sliz-Balogh, co-author of the thesis and professor at the Eötvös Loránd University in Budapest. "Astronomers are mostly overlooked, and it is curious that our planet has swine pseudosatellites in our orbit with our lunar neighbor.",

Although the clouds are several times larger than Earth, it is estimated that the particles that make them measure one micron of the circuit. The sun that is reflected in them makes it harder for them to shine, and if left hidden in the darkness of the universe, it's simply because they have a great lightness.
"It is very difficult to find Kordylewski clouds against galactic light, starlight, zodiacal light and sky brightness"said another co-author, Gábor Horváth, physicist Eötvös Lorand, NatGeo. To photograph them, the Hungarian team used polarization filters in cameras. By doing so, they have been able to detect the diffused light that is reflected from the individual particles in the clouds.
Generations of astronomers are thinking about Earth for more than a month, he remembered the article. They agreed on the existence of five points of stability, where they might be, called Lagrange Points. Kordylewksi investigated two of them, the L4 and L5 of the Earth-Moon system, during the 1950s and photographed them in 1961. There he continued their work, now Hungarian scientists.
