The most powerful millimetre/submillimetre-wavelength telescope in the world opens for business and reveals its first image
Alma's view of the Antennae galaxies, created using measurements from 16 of the dishes installed on the Chajnantor plateau in the Atacama desert, Chile. The Antennae are a pair of distorted spiral galaxies that are colliding about 70m light-years from Earth

A composite of Alma and Hubble observations of the Antennae galaxies. The blue colours represent the best-quality optical image taken of this region of space so far – by Hubble. The red, pink and yellow show previously unseen wavelengths of light emanating from the vast carbon monoxide clouds that float in and between the galaxies, imaged by Alma for the first time. The clouds contain gases with a total mass several billion times that of our sun
