We propose the concept of a "Galactic Habitable Zone" (GHZ). Similar to the circumstellar habitable zone (CHZ), the GHZ is that region in a spiral galaxy where life can exist. The width of the GHZ is controlled by two factors. The inner (closest to the center of the galaxy) limit is set by threats to complex life: nearby transient sources of ionizing ...

The Habitable Zone: Basic Concepts
2013The detection of exoplanets has undergone extraordinary growth over the past couple of decades since substellar companions were detected around HD 114762 (Latham et al., 9 1992, and 51 Peg (Mayor and Queloz, 1995. From there, the field rapidly expanded from the exclusivity of exoplanet detection to include exoplanet characterization.
