This new NASA/ESA Hubble Space Telescope image shows ghostly green filaments, lying within galaxy UGC 7342. This filament was illuminated by a blast of radiation from a quasar a very luminous and compact region that surrounds the supermassive black hole at the centre of its host galaxy. Its bright green hue is a result of ionised oxygen, which glows brightly at green wavelengths.
