ALMA surveyed the Hubble Ultra Deep Field

ALMA surveyed the Hubble Ultra Deep Field, uncovering new details of the star-forming history of the Universe. This animated GIF reveals one such galaxy (orange), rich in carbon monoxide, showing it is primed for star formation. The blue features are galaxies imaged by Hubble. Credit: B.
