Jupiter has over 60 known moons, but the big four are the real stars of the show: Io, Europa, Ganymede and Callisto. These are known as the Galilean satellites, so named for being discovered by astronomer Galileo Galilei around 1610. His observations revolutionized astronomy and helped change the common belief that Earth was the center of the universe.
NASA celebrates this legacy with a lovely time-lapse video showing the Juno spacecraft's view as it approaches Jupiter and its moons.
The time-lapse involves a sweet intro where the view tracks through a digital re-creation of Galileo's room, zooming up to his telescope and through the lens. The soundtrack soars as we watch Jupiter's moons rotate around the planet. The video fits in with NASA's recent penchant for dramatic movie-style videos, like this extremely fun trailer created for the Juno mission.
The footage covers images taken from June 12-29. Juno's distance from Jupiter during that time ranged from 10 million miles (16.1 million kilometers) away to 3 million miles (4.8 million kilometers) away. Juno successfully entered into orbit around Jupiter on July 4. The mission is focused on learning more about Jupiter's origin and evolution and is scheduled to last nearly two years.
