• Why Astrobiology? (ctd)

    We’ve seen two posts addressing the question “why study astrobiology?”, here and here. My take is very simple. There are three basic questions that any community of self-aware beings will eventually ask themselves, for reasons both practical and profound:

    • How did we get here?
    • Where are we headed?
    • Are we alone?

    The most direct way to answer these questions is exploration. To our ancestors, this meant exploring the next valley or the lands across the seas. To us, it means exploring the stars.
