This resource contains stunning images of nebulae, produced by the European Southern Observatory (ESO). The images include:
* View of the Orion Nebula (Messier 42), lying about 1,350 light-years from Earth, taken with the VISTA infrared survey telescope at ESO’s Paranal Observatory in Chile.
* A colour-composite image of the Helix Nebula (NGC 7293), showing oxygen atoms shining under the effects of the intense ultraviolet radiation of the 120,000 degree Celsius central star and the hot gas. Farther out from the star and beyond the ring of knots, the red colour from hydrogen and nitrogen is more prominent.
* A composite colour image of the Horsehead Nebula and its immediate surroundings. It is based on three exposures in the visual part of the spectrum.
* The Carina nebula, produced by images taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile.
* Vista of the Lagoon Nebula taken with the 67-million-pixel Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile.
