"ALMA - A Billion Dollar Radio Observatory in the Chilean Andes" - a presentation made by Dr. Andy Woodsworth to a meeting of the Royal Astronomical Society of Canada, Victoria Centre on December 8, 2010.
Canada is a participant in the development of this international radio observatory, which will represent a bigger advance in the field of radio astronomy than Hubble did in optical astronomy. This enormous observatory, which includes 66 large movable antennas in a 15 km area, is being built at the 5,000 metre level in the Atacama desert region of northern Chile.
This talk compared optical and radio astronomy, and explained some of the excitement behind the scientific potential and the very challenging technology development required to realize this potential. The talk also showed a few of the touristic aspects of the Atacama region.
