TED-Ed: There may be extraterrestrial life in our solar system - Augusto Carballido

The video explores the potential for life on ocean worlds like Europa, Enceladus, and Titan. These moons have liquid environments that could support life, similar to Earth's aquatic conditions. Europa's ocean, Enceladus' geysers, and Titan's methane lakes are examined for their life-supporting potential. Detecting life involves finding biosignatures while avoiding contamination. The video also highlights other potential ocean worlds in our solar system, suggesting vast possibilities for life beyond Earth.

What are biosignatures, and why are they important in the search for extraterrestrial life?

What challenges do astrobiologists face in ensuring that probes do not contaminate ocean worlds?

What potential does the text suggest exists for life beyond our solar system?
