first galaxies

A debate is resurfacing over when dark matter was first discovered. Some credit Fritz Zwicky, who in 1933 inferred unseen mass from the motions of galaxies in the Coma Cluster. Others point to Vera Rubin's 1970s observations of galactic rotation curves, which made the case impossible to ignore. Commenters argue the real history is richer than any single person's contribution, involving multiple astronomers building evidence over decades.

Astrophysicists at the Center for Astrophysics, run by Harvard University and the Smithsonian, have unveiled Lumina, a high-resolution cosmological simulation designed to model the first two billion years of cosmic history. The simulation integrates gravitational forces, gas dynamics and radiation transport to recreate how the early universe evolved, and researchers say it will help scientists study the formation of the first stars and galaxies.
