ALMA’s Antennae

Last December I was at an ALMA workshop, predicting that there would be beautiful first images from the new array within a year. Today one arrived, and it didn’t disappoint:

The Antennae galaxies as seen by ALMA (red, pink & yellow) and Hubble (blue)

This is ALMA’s view of the giant clouds of star-forming gas (red, pink and yellow) in the Antennae – a pair of colliding spiral galaxies – combined with the stars seen in the same system by the optical Hubble Space Telescope (blue). For lots more detail on the story check out this nice BBC News article. This image was made with only a small fraction of the dishes that will make up the final array so, all in all, the future’s looking pretty good for ALMA.
