You are looking at the first image returned by ALMA, the Atacama Large Millimeter/submillimeter Array, to be eventually comprised of 66 radio antennas on the Chajnantor plateau in northern Chile (though currently only a third completed), at an elevation of 5,000 meters. Its first image of the Antennae Galaxies (a pair of colliding galaxies) reveals a view of the Universe that cannot be seen at all by visible-light and infrared telescopes: the clouds of dense cold gas from which new stars form.
