Water Weirdness Sweaty Comets, and Titan's Hidden Oceans

The video explores the abundance of water in the solar system, challenging the notion that Earth's water makes it unique. It highlights Titan's potential subsurface oceans, which may be extremely salty, and discusses the implications for habitability. The Rosetta mission's observations of comet 67P reveal significant water vapor emissions, offering insights into the early solar system and the origins of water on planets and moons.

What makes Titan's subsurface oceans unique compared to Earth's oceans?

• They are composed of pure water.

• They are filled with sodium chloride.

• They are ten times saltier and contain different minerals.

• They are completely frozen.

How did scientists determine the presence of subsurface oceans on Titan?

• Through data from the Cassini spacecraft.

• By observing the surface with telescopes.

• Using satellite imagery.

• By sending a lander to Titan.

Why might Titan's subsurface oceans be less likely to support life?

• They lack any form of liquid.

• They are too cold.

• They are too salty and contain sulfur and potassium.

• They are too shallow.

What is the significance of the water vapor emission from comet 67P?

• It provides insights into the early solar system.

• It indicates the comet is habitable.

• It shows the comet is losing mass rapidly.

• It suggests the comet is melting.

What is the Rosetta mission's next major objective with comet 67P?

• To land on the comet and analyze its surface.

• To capture the comet's water vapor.

• To redirect the comet's path.

• To observe the comet from a distance.
