The Atacama Large Millimeter/sub-millimeter Array is an array of radio telescopes in the Atacama desert of northern Chile. Since a high and dry site is crucial to millimeter wavelength operations, the array has been constructed on the Chajnantor plateau at 5000 metres altitude. Consisting of 66 12-meter and 7-meter diameter radio telescopes observing at millimeter and sub-millimeter wavelengths, ALMA is expected to provide insight on star birth during the early universe and detailed imaging of local star and planet formation.
Images from initial testing
By the summer of 2011 sufficient telescopes were operational during the extensive program of testing prior to the Early Science phase for the first images to be captured.These early images give a first glimpse of the potential of the new array that will produce much better quality images in the future as the scale of the array continues to increase.
#Starburst galaxy--A starburst galaxy is a galaxy undergoing an exceptionally high rate of star formation, as compared to the long term average rate of star formation in the galaxy or the star formation rate observed in most other galaxies.
