  • In 1999 Gregory V. Hoppa, the late Randy Tufts, and a team of planetary scientists from the University of Arizona went a long way toward cracking the code, positing that the most mysterious fault lines identifiable on Europa — the wave-form-like "arcuate" fractures spiraling eerily across the crystalline landscapes near its poles — are almost certainly a result of Jupiter's shifting tidal pull on subsurface water.
