For decades the existence of weird space clouds in Earth's orbit has been speculative and controversial, but new research looks to validate their strange reality after all. The Kordylewski clouds – two mysterious swarms of dust trapped between the competing gravitational fields of Earth and the Moon – were first hypothesised back in the 1950s, although evidence for their existence was faint.For decades the existence of weird space clouds in Earth's orbit has been speculative and controversial, but new research looks to validate their strange reality after all. Now, a new study by researchers at Eötvös Loránd University in Hungary helps make the case for these unusual, ever-present satellites in the sky. "The Kordylewski clouds are two of the toughest objects to find, and though they are as close to Earth as the Moon, [they] are largely overlooked by researchers in astronomy," says first author of the study, astronomer Judit Slíz-Balogh. "It is intriguing to confirm that
