In January 1610, Galileo discovered the largest moons of Jupiter, including Europa. You can see them yourself with most binoculars or – as in this photo – a zoom lens. Jupiter and three moons can be seen at top center. Our mission will take a closer look: europa.nasa.gov

Two of Jupiter's moons, Io and Europa, floating peacefully above the planet's Great Red Spot – a permanent, violent storm, many times larger than the Earth. Unbelievably beautiful😍👽
