How Common Are Potential Habitable Worlds In Our Galaxy?
Imagine this scenario: You are planning to buy a new house in a nice neighborhood. The schools in the area are good, the neighborhood is very safe, but you want to know the ‘kid friendly’ area (so that your kids can have friends). You drive around, looking at the available houses, watching for any ‘kid signatures’. You notice that a good proportion of the homes in your neighborhood show some ‘potential’ to have kids. Based on your observation, you estimate the percentage of houses with kids. A very similar process is currently being carried out in the field of ‘exoplanets’: planets orbiting other stars.
Habitable Worlds And The Future Of Civilizations
Humans have gazed up at the sky in wonder since before the dawn of civilization, and the age-old question of “are we alone?” has occupied philosophers and priests for centuries on end. Today the interdisciplinary field of astrobiology strives toward an answer to this mystery by examining this history of life on Earth in an effort to search for life elsewhere and better understand our future.
