A stunning image of the Helix Nebula (NGC 7293), a planetary nebula located 700 light-years away in the constellation Aquarius. This detailed view, created from 58 hours of exposure, reveals the nebula's bright inner region (3 light-years across) and fainter outer halo (over 6 light-years across), showcasing its intricate structure and the central white dwarf star. The vibrant colours represent emission lines from hydrogen (red) and oxygen (blue-green).
