It looks like something out of a science fiction movie - giant antennas zooming in and out of a desert, their scopes trained on far-away galaxies.

At a cost of more than a billion dollars and nearly two decades in the making, the antennas form part of the world's most powerful telescope - called ALMA - which started operating on Tuesday.
