On this day in 1979, the Voyager I space probe had its closest approach to the planet Jupiter, and took this timelapse over the course of 60 Jovian days. The probe ended up taking over 19,000 pictures of the gas giant, while the sister probe Voyager II topped the number off to a total of 33,000 images of the planet and its satellites. These first close up images identified Jupiter’s ring system, the planet’s atmosphere, and the first evidence that the Great Red Spot is a complex storm pattern moving counterclockwise to the planet’s rotation. Voyager I has since moved past the planets and into the heliosphere, making it close to entering intersteller space, becoming the first man-made object to leave our Solar System.
