The spectacular planetary nebula NGC 7009, or the Saturn Nebula, emerges from the darkness like a series of oddly-shaped bubbles, lit up in glorious pinks and blues. This colourful image was captured by the MUSE instrument on ESO's Very Large Telescope (VLT). The map -- which reveals a wealth of intricate structures in the dust, including shells, a halo and a curious wave-like feature -- will help astronomers understand how planetary nebulae develop their strange shapes and symmetries.
