Mounted image 035: The Helix Nebula
A colour-composite image of the Helix Nebula created from images obtained by the Wide Field Imager, an astronomical camera attached to the MPG/ESO 2.2‑metre telescope at the La Silla Observatory in Chile. The blue-green glow in the centre of the Helix comes from oxygen atoms shining due to the intense ultraviolet radiation from the 120000 degree Celsius central star. Further out from the star and beyond the ring of knots, the red colour from hydrogen and nitrogen is more prominent.
