Galactic Life

A new study suggests the best place for life in the universe might be in giant, metal-rich galaxies with low rates of star formation.  Such galaxies, many times larger than the Milky Way, could have 10,000 times as many Earth-like planets in the habitable zones of their stars than does our home galaxy.

They could also have a million times more Earth-like moons orbiting gas giants which could also support life.
