An astronomer team has confirmed that there are two weak dust satellites floating approximately 400,000 km from the ground.
A new study examines a decades old report by Kazimierz Kordylewski who in 1
961 proposed the existence of ghostly clouds that form between the Earth and the Moon. But because it is so weak, it was difficult to observe and therefore the work caused controversy at that time.
In a new study published in the journal Monthly announcements from the Royal Astronomical Society astronomers from Hungary proved the presence of these clouds.
Lagrange points, named after the astronomer / mathematician Joseph-Louis Lagrange, are the gravitational points between two celestial bodies where objects can be captured. Between the Earth and its Moon there are five Lagrange points – including L4 and L5, as Lagrange himself predicted in 1772. These two gravitational points form a triangle between the earth and the moon, moving around the planet as the natural satellite movements in circulation.
Cloud clouds, which Kordylewski reported in 1961, is located at L5.
In a paper submitted earlier this year, a team led by Gábor Horváth from Eötvös Loránd University created a mathematical simulation to figure out how the dust shed will be formed and how they can be discovered from the ground. They found that a dam cloud, even a temporary, is quite possible within L5.
The astronomers then set up to find the dust cloud in L5. The team led to a private observatory in Hungary and used a linear polarizing filter system connected to a camera lens and a CCD detector.
After months of search, they finally found the clouds. From the images they received from the observatory, the team saw polarized light reflected from dust that stretches far beyond the visual field of the camera lens. This complies with the measurements from a separate previous study conducted by a team of Russian researchers.
“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 astronomers,” said Judit Slíz-Balogh, one of the authors of the paper. “It’s exciting to confirm that our planet has dusty pseudo satellites in circulation beside our neighbor.”
