Unveiling the dark regions of the Universe with ALMA

This image shows a glowing green antenna, part of the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA will be composed initially of 66 high precision antennas located on the Chajnantor plateau, 5000 metres altitude in northern Chile.

ALMA has started to deliver exciting science results and valuable clues about the formation and evolution of nearby planetary systems and has kept its promises by seeing through dark regions of the Universe made of gas and dust such as those seen in this image.
