Tiny Extremophiles Living in Rocks!

Endoliths are microorganisms that thrive in extreme environments, such as Antarctica's cold deserts, South Africa's deep gold mines, and beneath the ocean floor. These extremophiles survive by utilizing available resources like sunlight, chemical reactions, and nutrients from rocks. Their resilience offers insights into life's potential on other planets and supports the panspermia hypothesis, suggesting life could travel between worlds on asteroids. Endoliths help us understand life's limits and their potential impact on global climate.

Describe the conditions under which deep-biosphere endoliths live and how they obtain energy.

What implications does the study of endoliths have for the panspermia hypothesis?
