Capak et al.1 used 20 of ALMA's antennas to study the interstellar medium (ISM) of 9 galaxies that were present when the Universe was only about 1 billion years old. The authors found that their sources contain a smaller amount of dust than expected. Some of the galaxies in the sample may have an ISM similar to that of the Small Magellanic Cloud (a satellite galaxy of the Milky Way), which is visible here (right of centre) as the smaller of the two Magellanic Clouds above the antennas.
