‘The Atacama Large Millimeter/submillimeter Array, under construction. ALMA will be initially composed of 66 antennas, consisting a main array of fifty 12-meter antennas that can be spread over distances from 150 metres to 16 kilometers. In addition to the main array, ALMA will also have a compact array, composed of four 12-meter antennas plus twelve 7-meter antennas. By using the technique of interferometry, ALMA will work as a single giant telescope, enabling astronomers to observe the cold universe with unprecedented sensitivity and resolution.

‘A color composite of visible and near-infrared images of the dark cloud Barnard 68. It was obtained with the 8.2-m VLT ANTU telescope and the multimode FORS1 instrument in March 1999. At these wavelengths, the small cloud is completely opaque because of the obscuring effect of dust particles in its interior’ (ESO)
‘The KMOS spectrograph, shown when it was undergoing tests at the UK Astronomy Technology Center in Edinburgh, before it was shipped to Chile to become a powerful new instrument on the VLT. The 24 robotic arms are visible. (STFC/UKATC/ESO)’
Taking fourth prize in image processing, Renaud Houdinet (France) submitted a hugely ambitious mosaic of Hubble images. Chamaeleon I is a large nebula near the south celestial pole, and it does not fit into a single Hubble image. Renaud painstakingly tiled the exposures together. Despite the small gaps between the Hubble images, the jury was impressed by the technical achievement of putting together this ambitious vista. Houdinet said “Sometimes, things don’t turn out as they ought… It started as something promising, unfortunately it soon turned out there were quite a few ‘gaps’ between tiles that maybe weren’t so obvious looking at the footprint… It was a learning experience though!” (NASA/ESA/Renaud Houdinet) Hubbles Hidden Treasures
Fourth prize in image search, to Kathlyn Smith, for this portion of NGC 1579, a reflection nebula in the constellation of Perseus. (NAS/ESA/Kathlyn Smith) Hubbles Hidden Treasures

The center of our Galaxy is a busy place. In visible light, much of the Galactic Center is obscured by opaque dust. In infrared light, however, dust glows more and obscures less, allowing nearly one million stars to be recorded in the above image.
