Neowise appears over Mount Washington, as seen from the Dee Wright Observatory in Oregon, US. According to Nasa, the lower tail, which appears broad and fuzzy, is the dust trail while the upper part is the ion tail, made up of gases that have been ionised by losing electrons in the sun’s intense light
