Hubble observations of massive stars in metal-poor dwarf galaxies are revealing clues to why the early universe looks so unusual. Researchers found that stellar winds weaken sharply at extremely low metallicities, potentially allowing massive stars to retain more material and evolve in unexpected ways. The team also found large differences in iron abundance, a key ingredient in stellar winds and supernovae.

Black hole jets reach far beyond galaxies' visible edges, potentially deciding their fate
Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. This reservoir of raw material stretches 10–20 times th
