Summary:
- Astronomers have discovered a "mini-halo" of dark matter surrounding a galaxy from the early universe, providing new insights into the formation and evolution of galaxies.
- This mini-halo is much smaller than the typical dark matter halos found around galaxies today, suggesting that the early universe had a different distribution of dark matter compared to the present-day.
- The discovery of this mini-halo helps scientists understand how the first galaxies formed and evolved in the early universe, which is an important step in unraveling the mysteries of the cosmos.
