Asteroids and Alien Life

What is a common perception of asteroids?

• They are vital for space exploration.

• They are primarily composed of ice.

• They are harmless space objects.

• They are associated with doomsday scenarios.

How might asteroids have contributed to the emergence of life on Earth?

• By blocking sunlight.

• By delivering essential chemicals.

• By increasing Earth's gravity.

• By creating new species.

What significant event is linked to the extinction of dinosaurs?

• A volcanic eruption.

• A massive asteroid impact.

• A solar flare.

• A supernova explosion.

What hypothesis do Drs. Martin and Livio propose about asteroid belts?

• They are essential for life in star systems.

• They are only found in our solar system.

• They prevent life from forming.

• They are irrelevant to life formation.

What is the role of giant planets like Jupiter and Saturn in the solar system?
