With All These New Planets Found in the Habitable Zone, Maybe it's Time to Fine Tune the Habitable Zone

In the past few decades, thousands of extra-solar planets have been discovered within our galaxy. As of July 28th, 2018, a total of 3,374 extra-solar planets have been confirmed in 2,814 planetary systems. While the majority of these planets have been gas giants, an increasing number have been terrestrial (i.e. rocky) in nature and were found to be orbiting within their stars' respective habitable zones (HZ).

However, as the case of the Solar System shows, HZs do not necessary mean a planet can support life. Even though Mars and Venus are at the inner and the outer edge of the Sun's HZ (respectively), neither is capable of supporting life on its surface. And with more potentially-habitable planets being discovered all the time, a new study suggests that it might be time to refine our definition of habitable zones.

Welcome to the Inhospitable Zone.

    Exactly my point. Pretty weak production for a centuries of empire.
