Awesome Jupiter's Moons ! You never seen it before ! In January 1610, astronomer Galileo Galilei saw four points of light near Jupiter; but they didn't traverse the sky like other stars, they remained close to the planet. He realized he was seeing moons – the first discovered beyond Earth. In June 2016 as it approached Jupiter, NASA's Juno spacecraft enjoyed the same orbital ballet that Galileo witnessed, and captured a unique time-lapse movie of the Galilean moons in motion around the planet.
