The Future of Life in the Solar System

The video explores the future of the solar system as the Sun expands into a red giant in about 5 billion years. This expansion will shift the habitable zone outward, potentially making moons like Europa, Ganymede, Callisto, and Titan suitable for life. Europa's ocean could melt, providing energy sources for life, while Titan might host methane-based life. These new habitable zones will last for a limited time, offering a brief window for life to evolve. The video concludes with a call to support SciShow Space on Patreon.

What major change will occur to the Sun in about 5 billion years?

• It will transform into a black hole.

• It will shrink and cool down.

• It will become a red giant.

• It will explode into a supernova.

Which moon of Jupiter is considered a prime candidate for hosting life due to its subsurface ocean?

• Ganymede

• Callisto

• Europa

• Io

What is the primary reason Europa might become more habitable in the future?

• Its surface will become warmer.

• Its atmosphere will thicken.

• Its ocean will receive more sunlight and internal heat.

• Its magnetic field will strengthen.

What unique feature does Titan have that could support life?

• Lakes of liquid methane and ethane

• A thick oxygen-rich atmosphere

• Volcanic activity

• Lakes of liquid water

At what temperature in Kelvin could Titan's methane lakes become oceans?

• 200 Kelvin

• 150 Kelvin

• 100 Kelvin

• 250 Kelvin
