Nice article and cool telescope array but found it a little misleading in its terminology.
This is a 1mm array due to most frequencies above and below this are absorbed by the atmosphere. Pic. (http://www.google.co.uk/imgres?imgurl=http://www.udel.edu/Geography/DeLiberty/Geog474/spectrum.jpg&imgrefurl=http://www.udel.edu/Geography/DeLiberty/Geog474/geog474_energy_interact.html&h=524&w=1047&sz=70&tbnid=QsZ1lIXtCti5ZM:&tbnh=68&tbnw=136&zoom=1&usg=__wCtZxxfm3uvcu4FDTdyoze5cL_A=&docid=OXDAvezunDuIGM&hl=en&sa=X&ei=PhFCUbKbNu2S0QWN64HYDQ&ved=0CFcQ9QEwBQ) If you look at the pic you'll see a band gap a 0.1cm (1mm).
There's a lot of cool stuff going on in the IR bands but these are difficult from Earth due to the atmosphere.
QuoteALMA will be exponentially more powerful than any of its predecessors and about 10 times more powerful than NASA's Hubble telescope.
Hubble is a visible spectrum & IR telescope (http://www.google.co.uk/imgres?imgurl=http://www.jwst.nasa.gov/images/em_spectrum_satellite.jpg&imgrefurl=http://www.jwst.nasa.gov/comparison_about.html&h=232&w=649&sz=30&tbnid=faniBV40yDwIpM:&tbnh=43&tbnw=120&zoom=1&usg=__oAoUmRx8Cr-DmQAKNIE_BqOrjIk=&docid=05l2KoZGRpJkZM&hl=en&sa=X&ei=LBJCUciSDOiW0QXNiYCYAw&ved=0CFkQ9QEwBg&dur=1076) and doesn't look in the 1mm band. This is like comparing apples to oranges.
The article not withstanding, there should be some good data from these 'scopes.
