As it passed a hei ...read more
An artist’s impression of the Kordylewski cloud in the night sky (with its brightness greatly enhanced) at the time of the observations. (Credit: Gábor Horváth) A team of Hungarian astronomers and physicists may have finally confirmed two clouds of interplanetary dust orbiting Earth that were first reported in 1961. There are five points of stability in the Earth-moon system where gravitational forces keep objects in position. Scientists call these “Lagrange points,&r ...read more
