Europa's Hidden Alien Ocean
from Major Gazer
Europa hides a 40–100-mile-deep salty ocean—holding 2–3x Earth’s water—kept warm by Jupiter’s squeeze and possibly shooting 100-mile plumes. Galileo caught the ocean’s magnetic signature; Hubble saw hints of geysers; now ESA’s JUICE and NASA’s Europa Clipper will fly by to sniff for life.
