Galaxies in the Infant Universe were Surprisingly Mature

October 28, 2020 | Science

These are two of the galaxies in the early universe that ALMA observed in radio waves. The galaxies are considered more “mature” than “primordial” because they contain large amounts of dust (yellow). ALMA also revealed the gas (red), which is used to measure the obscured star-formation and motions in the galaxies. (Credit: B.

Massive galaxies were already much more mature in the early universe than previously expected. This was shown by an international team of astronomers who studied 118 distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA).
