The Atacama Large Millimeter/submillimeter Array (ALMA) is an international partnership of Europe, North America ,and East Asia in cooperation with the Republic of Chile. ALMA is a telescope of revolutionary design. It will be composed initially of 66 high precision antennas located on the Chajnantor plateau, 5000 meters altitude in northern Chile. ALMA will observe at wavelengths in the range 3 mm to 400 ?m (84 to 720 GHz) and will be 10-100 times more sensitive and will have 10-100 times better angular resolution than current millimeter interferometers. The design of ALMA is driven by three key science goals: The ability to detect spectral line emission from CO or [CII] in a normal galaxy like the Milky Way at a redshift of z=3 in less than 24 hours, the ability to image the gas kinematics in protostars and in protoplanetary disks around young Sun-like stars in the nearest molecular clouds (150 pc), and the ability to provide precise high dynamic range images at an angular resolution of 0.1 arcsec. ALMA Early Science operations started on September 2011 and yielded more than 60 publications in refereed journals so far. In this talk, I will present the ALMA history, its current status, and I will give a general overview on the capabilities offered in the next Cycle 2 call for proposal.
