As far as we know, we’re still alone in the solar system, but now our moon has company. After more than half a century of speculation and controversy, Hungarian astronomers and physicists say they have finally confirmed the existence of two Earth-orbiting “moons” entirely made of dust.”

Long before the official discovery, researchers inferred the existence of these moons. The clouds were first reported by Polish astronomer Kazimierz Kordylewski in 1961, who made the discovery while investigating two points in the Earth-Moon system where two gravitational forces interact in a way that stabilises the position of objects, known as a Lagrange point. Hungarian astronomers have confirmed, catching the long-rumored satellites on film.Researchers have suspected the moons were there since 1961, when Polish astronomer Kazimierz Kordylewski spotted the two bright spots, but their existence remained controversial.The KordylewskiSunlight reflecting off the particles makes them glow, but they are difficult to see from Earth due to the comparative brightness of other objects in space.Putting to rest years of speculation, researchers Judit Slíz-Balogh and Gábor Horváth of Eötvös Loránd University finally immortalized the clouds on film using special polarizing filters on their cameras. The two clouds photographed by the researchers were located near the L5 point, and they believe there may be similar formations near L4.which then require minimal fuel to stay in orbit.
A new study from Eötvös Loránd University confirms the existence of two Kordylewski clouds orbiting Earth. Kazimierz Kordylewski first observed the faint clouds of dust around the L4 and L5 Lagrangian points in the 1960s.
