huge hurricane like storm systems when you have opposing jet streams they 36 00:01:01,580 --> 00:01:01,590 when you have opposing jet streams they 37 00:01:01,590 --> 00:01:03,830 when you have opposing jet streams they tend to generate vortices or small 38 00:01:03,830 --> 00:01:03,840 tend to generate vortices or small 39 00:01:03,840 --> 00:01:06,289 tend to generate vortices or small storms and those small storms collide 40 00:01:06,289 --> 00:01:06,299 storms and those small storms collide 41 00:01:06,299 --> 00:01:08,539 storms and those small storms collide with each other and accumulate to make 42 00:01:08,539 --> 00:01:08,549 with each other and accumulate to make 43 00:01:08,549 --> 00:01:12,350 with each other and accumulate to make one large storm Voyager 2 also found

in a retrograde orbit that 66 00:01:40,520 --> 00:01:40,530 moon which is in a retrograde orbit that 67 00:01:40,530 --> 00:01:41,870 moon which is in a retrograde orbit that is it's orbiting backwards around 68 00:01:41,870 --> 00:01:41,880 is it's orbiting backwards around 69 00:01:41,880 --> 00:01:43,520 is it's orbiting backwards around Neptune compared to the way Neptune is 70
