Helix Nebula, Galaxies and Stars Button

Galaxies, Stars and Nebulae series A fantastic colour-composite image of the Helix Nebula (NGC 7293). 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.

Congratulations, enlarged area of The Omega Nebula Greeting Card
tagged with: outer space, congratulations, congrats, well done, omega nebula m17, hrbstslr eroton, galaxy stars, good job, universe astronomy, young massive stars, star forming activity, red sulpher, green hydrogen, blue oxygen, ultraviolet radiation
Galaxies, Stars and Nebulae series Like the fury of a raging sea, this bubbly ocean of glowing hydrogen, oxygen, and sulphur gas lies in the extremely massive and luminous molecular nebula Messier 17.
This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation.
Ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds and the warmed surfaces glow orange and red. The intense heat and pressure causes some material to stream away from the surface, creating the glowing veil of even hotter green-coloured gas that masks background structures. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen.
