Kordylewski cloud
Kordylewski clouds are clumps of dust located at 2 out of the 5 special points in space between the Earth and the Moon. The 2 special points are called L4 and L5 Lagrange points.[1][2][3] They were discovered by a Polish astronomer in the 1960s, and recently confirmed by the Royal Astronomical Society in October 2018.[1][2][3]
Discovery and observation
changeKordylewski searched for clouds of dust at the Lagrange points in 1951.[4][5] He first saw them in 1956.[6] He then succeeded in photographing two bright patches near the L5 Lagrange point in between 6 March 1961 to 6 April 1961. J. Wesley Simpson observed the clouds in 1967 using the Kuiper Airborne Observatory, and in 2018, the Royal Astronomical Society confirmed their existence.[1][2][3] However, the Japanese Hiten space probe did not find the clouds in 1992,[6][7] although this does not mean they are not there.[8]
