Study: Exoplanets Could Have Better Conditions For Life Than Earth

(CNN) — Earth seems like the perfect hub for life because it’s the only planet known so far to host it.
But new research suggests that other planets could have oceans that are even more hospitable, offering life that is more varied than we know it.
Researchers used NASA-developed software called ROCKE-3D to simulate ocean circulation and climates on different types of exoplanets, or planets outside our solar system.
Oceanic life on Earth depends on an upward flow, or upwelling, which
