Story summary

The James Webb Space Telescope, led by University of Cambridge researchers, shows early galaxies formed shortly after the Big Bang and were chaotic and gas-rich, based on 250 analyzed young galaxies.
The analysis found turbulence and starbursts dominated formation, signaling a transition from chaos to stability.
Tel Aviv University researchers studied faint radio waves from the cosmic dark ages, suggesting dark matter clumps influenced hydrogen gas emissions.
