Detailed studies of galaxy and AGN evolution exploiting the unique data set of the Millennium Simulation therefore make stringent new tests of the theory of hierarchical galaxy formation possible.

The Milky Way is not just a band of stars stretching across the night sky; it's a massive, dynamic galaxy spanning over 200,000 light-years and containing hundreds of billions of stars, planets, and ...

The formation of galaxies is still one of the most active research areas in astrophysics; and, to some extent, this is also true for galaxy evolution. Some ideas, however, are now widely accepted.
