About This Design
Helix Nebula, Galaxies and Stars 15 Cm Square Badge
Galaxies, Stars and Nebulae series: A fantastic colour-composite image of the Helix Nebula (NGC 7293) - aka The Eye of God. It was created from images obtained using the Wide Field Imager (WFI), an astronomical camera attached to the 2.2-metre Max-Planck Society/ESO telescope at the La Silla observatory in Chile.
The blue-green glow in the centre of the Helix comes from oxygen atoms shining under effects of the intense ultraviolet radiation of the 120 000 degree Celsius central star and the hot gas.
Further out from the star and beyond the ring of knots, the red colour from hydrogen and nitrogen is more prominent. A careful look at the central part of this object reveals not only the knots, but also many remote galaxies seen right through the thinly spread glowing gas.
