The ground may be accompanied by several ghostly moons

According to a new study, which is based on the hypothesis 60 years ago, around the Earth can rotate ghostly companion... from dust.

It is known that massive objects attract each other due to gravity. But when there are some huge objects with certain masses, their mutual gravitational field you can create some anomalies — gravity point within which objects can remain stable. Scientists have discovered objects orbiting of the Lagrange points created by the combined gravity of Sun and Mars, Sun and Neptune, and the Sun and Jupiter. Now, researchers have reported clouds of dust called cloud Kordylevskogo, of the Lagrange points created by the gravity of Earth and moon.

The Swiss mathematician Leonhard Euler predicted the existence of three singular points in 1767, and the Italian astronomer and mathematician Joseph Louis Lagrange proved mathematically that the existence of points in 1772. Today, scientists know all about them — the space telescope, the James Webb will orbit the Sun and the Earth in a stable Lagrange point L2.

The earth and Moon have the correct ratio so that a certain amount of mass can stably rotate around the system of the Lagrange points L4 and L5, in fact, discovered by Lagrange. Polish scientist Kazimierz Kordylewski in 1961 found evidence that points L5 are rotating dust cloud. Since then there have been few studies of this phenomenon. But over the past two months the team of scientists conducted a study to determine whether or not these clouds to exist, despite the gravity of the Sun or solar winds. The team of the University of Eotvos Lorand began with mathematical modeling, based on calculations of the system containing the Sun, the Earth, the moon, and a cloud of dust. They found that the swirling, ever-changing dust cloud may exist at the point L5. This confirms another analytical work of Russian scientists, published a month earlier.

But if they saw a cloud Kordylevskogo? The team used private Observatory study author Judita was Tears-Balogh in Hungary using special lenses that can measure the polarization of light. Scientists hoped to be able to see the proof of the existence of dust clouds by the polarization of the light emanating from the L5. And they found such evidence, but not without effort. "After several months of observation (moonless and cloudless night in Hungary — a rarity), we were able to observe the dust cloud from the Lagrange point L5 two nights in a row", — reported in the second article.

Although the team has used in its work, the modeling and surveillance, you still should treat their findings with a grain of salt. According to the article, the observations were able to show a temporary phenomenon — any dust, which they saw could be deflated by the gravitational forces from other planets or the solar wind.

Many other telescopes, and a Japanese probe found no evidence of the existence of clouds of dust, while other observations found. However, it should be noted that the researchers tried to rule out any other potential sources of polarized light. Scientists say that their method of observation was ideal for the search cloud.

So, is there a cloud Kordylevskogo? New research govoroyat us that Yes — and if this is true, it means that we have at least one, if not two, Shadowmoon, and the probability of the existence of another cloud of dust at the point L4.
