Hubble view of green filament in galaxy UGC 7342
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.
