Transcript

• Europa is one of Jupiter's moons. It's kind of about the same size as our own moon but a really different structure. It has this rocky interior, but it's surrounded by this global ocean. And on top of that ocean, we've got this ice shell that's maybe as much as 20 to 30 kilometers thick. The heat and chemical signatures that are there suggest it ... Read More

Questions & Answers

Q: What makes Europa a potential candidate for extraterrestrial habitability?

Europa's rocky interior, global ocean, and ice shell create a promising environment for life as liquid water near the surface increases the chances of habitability.

Q: How do scientists study Europa's subsurface when they can't see it directly?

Scientists analyze the various surface features, such as double ridges and chaos terrain, to gain insights into Europa's interior and its potential for supporting life.

Q: What is the significance of the "double ridges" on Europa?

Double ridges are common surface features on Europa that could provide valuable information about the moon's subsurface dynamics and the formation of habitable conditions.

Q: How can studying surface features on Earth help us understand Europa?

By studying the processes that form similar ridges on Earth's surface, scientists can gain knowledge about the dynamics that shape Europa's landscape and potential for life.
