E pluribus unum

Centre-stage in this image is one of the array of dishes that make up the ALMA telescope. In the background are some of its 65 fellow telescopes, operating together to produce some of the sharpest astronomical images imaginable using light at millimetre and submillimeter wavelengths. This photograph was taken by one of a team of crack photographers — the Fulldome Expedition — who are visiting ESO's observatories in Chile to obtain spectacular images for use in planetarium presentations
