16.0 Learning Objectives

In this chapter, students will learn how to:

• Identify key concepts and terminology related to astrobiology, such as the Copernican principle, organic molecules, photosynthesis, and habitable environments.
• Evaluate the Fermi paradox and various proposed solutions, considering the implications for the prevalence of intelligent life in the universe and the potential for interstellar communication or travel.
• Compare and contrast the ability of different microorganisms to use various chemical energy sources for survival.
• Analyze the factors that contribute to the thriving microbial life in extreme conditions, such as hot springs, acidic environments, and high-pressure regions.
• Explain the factors that define a planet’s habitability, including surface temperature, atmosphere, and distance from the star.
• Utilize the Drake Equation to estimate the number of potential communicating civilizations in the Galaxy, given specific assumptions and values for its factors.
• Form a well-reasoned argument about the likelihood of finding intelligent life in the universe and its potential implications for humanity.
