Can surface fractures on Earth, Mars, and Europa predict habitability on other planets?
A view of a planet in the solar system.

(On homepage) A global view of Jupiter’s moon Europa displaying extensive surface fractures—long, curving lines carved into the ice by tidal forces from Jupiter. These cracks hint at dynamic activity beneath Europa’s frozen shell and may provide clues about the moon’s potentially habitable subsurface ocean.

Can surface fractures on Earth, Mars, and Europa predict habitability on other planets?

Geophysicist Douglas Jerolmack has used the mathematical framework developed for understanding fracture patterns on Earth to survey two-dimensional fracture networks across the solar system, which could offer insights into detecting potentially habitable environments on other planets.
