Technician Enrique Garcia checks electronics on the @ALMA.Radiotelescope correlator, housed 5000-metres above sea level at the Array Operations Site (AOS). Due to the extreme altitude, he's using supplemental oxygen.

Usually the black probe goes on the chassis ground, but the magnitude should be the same.

The impressive ALMA transporters! 20 metres long and 10 metres wide, these trucks are able to position an ALMA antenna to millimetre accuracy — ESO Picture of the Week.

At the very centre of the image, the ghostly tendrils of a red sprite — a ghostly phenomenon that occurs at high altitudes above thunderstorms.

This snowy image shows the @ALMA.Radiotelescope antennae atop the #Chajnantor Plateau in the #Atacama Desert, northern #Chile. In the background, the 5920-metre-high Licancabur volcano can be seen. Credit: @ESOAstronomy /M. Alexander http://socsi.in/3HZr1

Introduction
Welcome to the official page of the European Southern Observatory, the world's most productive ground-based observatory!

ESO, the European Southern Observatory, provides state-of-the-art research facilities to European astronomers and astrophysicists. It is an intergovernmental organisation with 15 member-states.

ESO carries out an ambitious programme focused on the design, construction and operation of even more powerful observing facilities.
ESO has enabled the first picture of a planet around another star, measured the distance to the most remote object ever found, found the largest solar system yet around another star and contributed to the discovery of the Universe’s accelerating expansion due to the elusive dark energy.
