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 is unique. It highlights Titan's subsurface oceans, which may be extremely salty, and discusses the Rosetta mission's findings on comet 67P, which emits significant water vapor. These discoveries have implications for understanding the solar system's history and the origins of water on planets and moons.

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

• They contain no salt at all.

• They are ten times saltier than Earth's oceans.

• They are composed of pure water.

• They are warmer than Earth's oceans.

What did the Cassini spacecraft use to detect liquid water beneath Titan's surface?

• Infrared imaging

• Radio waves

• Ultraviolet light

• Magnetic resonance

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

• They lack any form of salt.

• They are too cold.

• They are full of sulfur and potassium salts.

• They are too shallow.

What is the significance of comet 67P releasing water vapor?

• It suggests comets may have contributed water to planets.

• It indicates the comet is melting.

• It proves the comet is made entirely of ice.

• It shows the comet is losing mass rapidly.

What is the Rosetta mission planning to do with comet 67P?

• Use it to test new spacecraft technology.

• Capture the comet and bring it to Earth.

• Melt the comet to study its core.

• Land on its surface and analyze samples.
