This beautiful photo by José Francisco Salgado shows four antennas of the Atacama Large Millimetre/submillimetre Array (ALMA) gazing up at the star-filled night sky. The Moon is visible to the right whilst the Milky Way can be seen stretching across the upper left. ALMA, consisting of 66 antennas, is being built at an altitude of 5000m way up on the Chajnantor plateau in the Atacama Desert in Chile. The Atacama desert is one of the driest spots on earth. This combined with the thin atmosphere at high altitude means that ALMA is well positioned to make use of awesome viewing conditions for observing the Universe at millimetre and submillimetre wavelengths. With ALMA coming online by the end of 2012, astronomers will be able to find out all sorts of trippy things about the origins of stars, galaxies and planets. Check out the timelapse from which this pic was taken:

Hello Joseph,
is it possible to use the picture “four atennas” in a slideshow for a clients Powerpoint Presentation? Who owns the Copyrights for this pic?
Yours, Tom
Hi Tom, the photo is available on the Wikimedia commons here: http://en.wikipedia.org/wiki/File:Four_antennas_ALMA.jpg
According to the creative commons license one just needs to attribute the original photographer (which I naughtily didn’t do originally – now fixed!)
Thank you for your quick responding!
