A Seafloor Spreading Slowdown May Have Slashed Sea Levels
Between 15 million and 6 million years ago, a drop in ocean crust production may have lowered sea level by 26–32 meters.
Jupiter’s Moon Callisto Is Very Likely an Ocean World
A closer look at previously disregarded observations reveals stronger evidence that a deep ocean lies beneath Callisto’s icy surface.
Ceres’s Organics Might Not Be Homegrown After All
Scientists have been unable to determine whether the dwarf planet’s organics were produced by its own chemical processes or delivered by asteroids. New evidence implicates asteroids.
