The Ripples on Titan's Lakes that Shocked NASA Scientists

The video explores the Cassini mission's discoveries about Titan, Saturn's moon, focusing on its methane lakes. It compares Earth and Titan, highlighting differences in atmosphere and surface conditions. Cassini's radar and infrared instruments revealed Titan's lakes, which are mostly near the poles and vary with seasons. The video discusses theories about the lakes' formation, including explosion craters. Despite Cassini's extensive data, many mysteries remain, and future missions are anticipated to further explore Titan and the Saturn system.

What was one of the most significant discoveries made by the Cassini mission on Titan?

• Presence of liquid water oceans

• Detection of volcanic activity

• Existence of liquid methane lakes

• Discovery of new moons

How does Titan's atmosphere differ from Earth's?

• Titan's atmosphere is thinner and less dense

• Titan's atmosphere is thicker and extends higher

• Titan's atmosphere is composed mainly of oxygen

• Titan's atmosphere is warmer than Earth's

What cycle on Titan is similar to Earth's water cycle?

• Carbon cycle

• Sulfur cycle

• Nitrogen cycle

• Methane cycle

What is surprising about the lakes on Titan?

• They are extremely turbulent

• They are filled with water

• They are surprisingly still

• They have no liquid at all

What method did Cassini use to detect lakes on Titan?

• Magnetic resonance imaging

• Specular reflection with radar and infrared

• Ultraviolet imaging

• X-ray diffraction

Where are most of Titan's lakes located?

• Near the poles

• In the southern hemisphere

• In the western hemisphere

• Near the equator

What is one theory about the formation of steep-rimmed lakes on Titan?

• They are formed by erosion

• They are volcanic craters

• They are explosion craters filled with methane

• They are impact craters from asteroids
