  • A mature galaxy has been discovered in an early phase of the Universe apparently too young to contain it. Is this the end of the theorists' favourite cosmology, the Einstein–de Sitter model?

  • A fine marriage between galaxy data and theoretical simulations offers an explanation for two apparently conflicting sets of observations on the rate at which stars formed at early cosmic times.

  • How galaxies form their stars has been extensively studied but the role of the galactic gas content and the efficiency of its conversion into stars remain to be fully understood. Here the author presents a data-driven statistical analysis that reduces potential biases related to non-detections to quantify the link between star formation, molecular, and neutral gas in nearby galaxies.

  • High-resolution observations of early galaxies have shown that two-thirds are massive rotating disk galaxies with velocity dispersions typically five times higher than in today's galaxies. These authors report observations of a sample of rare, high-velocity-dispersion disk galaxies. They find that their velocity dispersions are correlated with their star formation rates, but not their masses or gas fractions, suggesting that star formation is the energetic driver of galaxy disk turbulence at all cosmic epochs.

  • Submillimetre-bright galaxies at high redshift are the most luminous, heavily star-forming galaxies in the Universe, but cosmological simulations of such galaxies have so far been unsuccessful; now a cosmological hydrodynamic galaxy formation simulation is reported that can form a submillimetre galaxy that simultaneously satisfies the broad range of observed physical constraints.

  • The Sloan Digital Sky Survey represents the most ambitious attempt yet to map out a slice of the sky. In the first five years of its existence, it has revealed cosmic structures on every conceivable scale.

  • These days, galaxies come in very different shapes and sizes. Cutting-edge technologies allow a detailed peek at how things looked in the Universe's early days — 'the same, but different' is the tentative message.
