Milky Way may have begun as thousands of galaxies, new simulations suggest
New supercomputer simulations indicate the Milky Way began as a collection of over 1,000 small galaxies during the cosmic dawn. These early structures varied significantly in composition: some produced stars at a frantic pace, some contained only gas, and others consisted of black holes and dead stars. This rendering provides insight into how our home galaxy evolved from a swarm of tiny galaxies into its current form.

Simulations suggest Milky Way evolved from thousands of small galaxies
New supercomputer simulations indicate the Milky Way began as a collection of over 1,000 small galaxies during the cosmic dawn. These early structures varied significantly in composition: some produced stars at a frantic pace, some contained only gas, and others consisted of black holes and dead stars. This rendering provides insight into how our home galaxy evolved from a swarm of tiny galaxies into its current form.
Why it matters
Understanding the cosmic dawn helps scientists map early star formation and galactic evolution. These findings link the first stars to the eventual structure of the Milky Way neighborhood.
What is confirmed
- The Milky Way may have started as a collection of thousands of smaller galaxies.
- Early galactic structures in the Milky Way neighborhood included some that produced stars rapidly, some containing only gas, and others filled with black holes and dead stars.
- New simulations reveal the Milky Way evolved from over 1,000 small galaxies.
What to watch next
- Further data from the James Webb Space Telescope regarding early supermassive black holes
- Additional results from the MEGATRON simulation regarding the first stars
