Astronomy and Physics - NASA Jet Propulsion Laboratory (JPL)
The first stars formed maybe a few hundred million years after the Big Bang, and the peak of star formation occurred after 3 or 4 billion years. Galaxies are giant collections of stars and dark matter. Less than 10% of all the baryons (protons, neutrons, electrons — the kind of matter stars and we are made of) wind up in stars.
