Australian Photographer Captures Exact Moment ISS Passed Through Jupiter-Saturn Conjunction FOLLOW US ON: An Australian photographer has captured a photograph in which the International Space Station (ISS) can be seen moving between Jupiter and Saturn during the Great Conjunction, reported Colossal. The Great Conjunction is when two planets appear closest together in the sky. This event occurs roughly every two decades. But the one that happened this year on December 21 was special because, during this Great Conjunction, Jupiter and Saturn appeared closer together in the sky than they have since March 4, 1226. Many photographers and space enthusiasts trained their cameras towards the event and shot photos of the event. However, one among them definitely stands out for capturing ISS, a habitable artificial satellite and a multinational collaborative project, moving between the two glowing planets.
