ALMA's spectrum range
Catherine Cesarsky - International Astronomical Union

ALMA will work at the millimeter and sub-millimeter range, which means the wavelengths, these are microwaves and their wavelength is of that size, between one millimeter to a tenth of a millimeter, .3 millimeters, actually, for ALMA. This is a wavelength that has been least explored in astronomy these days, and so the potential for discovery is absolutely enormous.

In addition to looking at nearby regions or star formations also to study the composition of these clouds which will contain complicated molecules which are probably the first elements to build life, ALMA will also be capable of doing very important discoveries in the very far away universe.
