Summary:
- NASA's Juno spacecraft has measured the thickness of the ice shell on Jupiter's moon, Europa. This is an important finding as Europa is believed to have a subsurface ocean, which could potentially host life.
- The data from Juno's gravity measurements suggests that Europa's ice shell is between 15 to 25 kilometers (9 to 16 miles) thick, which is thinner than previously thought.
- Understanding the thickness of Europa's ice shell is crucial for future missions that aim to explore the moon's subsurface ocean and potentially search for signs of life.
