The Galactic Habitable Zone

A proposed — and much-debated — region of the Galaxy thought to be most favourable to complex life: far enough from the crowded, radiation-soaked centre yet metal-rich enough to build planets. Whether such a zone is truly well-defined remains an open question, and it is offered as a hypothesis rather than an established boundary.
