Alien life might be making methane on Saturn’s moon

The video discusses the potential for life on Saturn's moon Enceladus, based on data from the Cassini space probe. In 2005, Cassini detected geysers containing dihydrogen, water ice, and methane. Methane is typically produced by bacteria on Earth but can also result from geological processes. Researchers used mathematical models to assess the likelihood of non-biological methane production, suggesting a possibility of life. The study also explores geochemical processes that could produce methane without biological activity.

What did the Cassini space probe discover on Enceladus that suggests the possibility of life?

• Atmospheric storms

• Volcanic activity

• Lakes of liquid water

• Geysers of ice particles

Which of the following is NOT a component found in the geysers on Enceladus?

• Dihydrogen

• Water ice

• Methane

• Carbon dioxide

On Earth, methane is commonly produced by which of the following?

• Ocean currents

• Bacteria

• Wind erosion

• Volcanic eruptions

What are scientists trying to determine about the methane on Enceladus?

• If it is affecting the moon's orbit

• If it is being produced by living organisms

• If it is causing climate change

• If it is depleting the moon's resources

What is the significance of finding methane on Enceladus?

• It indicates volcanic activity

• It shows the moon's atmosphere is thickening

• It suggests the presence of water

• It could imply the existence of life
