1 00:00:04,470 --> 00:00:02,389 [Music] 2 00:00:06,150 --> 00:00:04,480 what's up for september 3 00:00:08,470 --> 00:00:06,160 mars on the move 4 00:00:10,549 --> 00:00:08,480 prime viewing time for jupiter and a 5 00:00:12,070 --> 00:00:10,559 clever way to find your bearings on the 6 00:00:14,470 --> 00:00:12,080 equinox 7 00:00:16,070 --> 00:00:14,480 you'll find mars hanging out high in the 8 00:00:17,269 --> 00:00:16,080 south on september mornings before 9 00:00:18,710 --> 00:00:17,279 sunrise 10 00:00:21,029 --> 00:00:18,720 early in the month it's near 11 00:00:22,630 --> 00:00:21,039 orange-colored aldebrain the eye of 12 00:00:24,470 --> 00:00:22,640 taurus the bull 13 00:00:26,470 --> 00:00:24,480 and over the course of the month mars 14 00:00:29,109 --> 00:00:26,480 works its way eastward from aldebaran 15 00:00:32,549 --> 00:00:29,119 toward reddish beetlejuice creating a 16 00:00:34,630 --> 00:00:32,559 sort of red triangle in the morning sky 17 00:00:37,030 --> 00:00:34,640 then the red planet will appear to hit 18 00:00:38,630 --> 00:00:37,040 the brakes and halt its eastward motion 19 00:00:40,630 --> 00:00:38,640 to hang out in that triangle for the 20 00:00:43,030 --> 00:00:40,640 next month or so we'll talk about what's 21 00:00:44,790 --> 00:00:43,040 going on there in our october video 22 00:00:47,029 --> 00:00:44,800 on the morning of the 11th before 23 00:00:48,709 --> 00:00:47,039 sunrise you'll find the moon just a 24 00:00:51,029 --> 00:00:48,719 couple of finger widths from jupiter on 25 00:00:52,630 --> 00:00:51,039 the sky making for a great viewing 26 00:00:54,069 --> 00:00:52,640 opportunity to observe them together 27 00:00:56,150 --> 00:00:54,079 through binoculars 28 00:00:58,069 --> 00:00:56,160 jupiter is at opposition this month 29 00:00:59,910 --> 00:00:58,079 making it visible all night under clear 30 00:01:01,590 --> 00:00:59,920 skies and it's around this time when the 31 00:01:03,590 --> 00:01:01,600 planet's at its biggest and brightest 32 00:01:05,509 --> 00:01:03,600 for telescope viewing but a pair of 33 00:01:07,510 --> 00:01:05,519 binoculars is enough to reveal the giant 34 00:01:09,190 --> 00:01:07,520 planet's four large moons as little 35 00:01:10,390 --> 00:01:09,200 star-like points of light next to 36 00:01:14,789 --> 00:01:10,400 jupiter 37 00:01:17,350 --> 00:01:14,799 juno spacecraft is slated to make a 38 00:01:20,710 --> 00:01:17,360 special vast flyby of one of those icy 39 00:01:22,550 --> 00:01:20,720 moons europa on the 29th the spacecraft 40 00:01:24,550 --> 00:01:22,560 is planned to pass a little over 200 41 00:01:26,550 --> 00:01:24,560 miles above the moon's surface returning 42 00:01:28,310 --> 00:01:26,560 images and science data 43 00:01:30,469 --> 00:01:28,320 and nasa is currently preparing its 44 00:01:32,069 --> 00:01:30,479 europa clipper spacecraft for launch in 45 00:01:33,670 --> 00:01:32,079 2024 46 00:01:35,990 --> 00:01:33,680 it's planned to make dozens of close 47 00:01:37,749 --> 00:01:36,000 flybys of europa to investigate whether 48 00:01:39,749 --> 00:01:37,759 the moon could have conditions suitable 49 00:01:41,590 --> 00:01:39,759 for life 50 00:01:43,510 --> 00:01:41,600 turning to the evening sky you'll have 51 00:01:46,230 --> 00:01:43,520 saturn together with jupiter as your 52 00:01:48,149 --> 00:01:46,240 planetary companions all month long 53 00:01:51,109 --> 00:01:48,159 on the night of the 9th jupiter and 54 00:01:53,109 --> 00:01:51,119 saturn escort the moon across the sky 55 00:01:54,870 --> 00:01:53,119 you'll find the trio rising in the 56 00:01:57,109 --> 00:01:54,880 southeast in the first couple of hours 57 00:01:59,030 --> 00:01:57,119 after dark and gliding westward together 58 00:02:00,310 --> 00:01:59,040 over the course of the night by the end 59 00:02:02,469 --> 00:02:00,320 of the month you'll find the pair of 60 00:02:04,469 --> 00:02:02,479 planets is rising even earlier appearing 61 00:02:08,150 --> 00:02:04,479 in the east soon after it gets dark with 62 00:02:10,229 --> 00:02:08,160 bright jupiter hanging low in the sky 63 00:02:12,390 --> 00:02:10,239 september 23rd brings the september 64 00:02:13,990 --> 00:02:12,400 equinox which marks the start of fall in 65 00:02:16,070 --> 00:02:14,000 the northern hemisphere and the start of 66 00:02:18,150 --> 00:02:16,080 spring in the southern hemisphere the 67 00:02:19,990 --> 00:02:18,160 equinoxes occur twice per year when 68 00:02:22,470 --> 00:02:20,000 earth's tilt with respect to the sun is 69 00:02:24,309 --> 00:02:22,480 the same for both hemispheres both north 70 00:02:26,869 --> 00:02:24,319 and south receive the same amount of 71 00:02:29,030 --> 00:02:26,879 sunlight and day and night are briefly 72 00:02:31,670 --> 00:02:29,040 of nearly equal length 73 00:02:34,229 --> 00:02:31,680 and get this if you take note of exactly 74 00:02:36,710 --> 00:02:34,239 where the sun appears to rise and set on 75 00:02:39,270 --> 00:02:36,720 the equinoxes those points mark the 76 00:02:41,509 --> 00:02:39,280 locations of due east and due west 77 00:02:43,350 --> 00:02:41,519 respectively and that's something useful 78 00:02:45,270 --> 00:02:43,360 to know for sky watchers whatever 79 00:02:47,670 --> 00:02:45,280 hemisphere you happen to live in 80 00:02:49,509 --> 00:02:47,680 so take note of any buildings tall trees 81 00:02:50,390 --> 00:02:49,519 lamp posts and the like at those places 82 00:02:51,750 --> 00:02:50,400 on the horizon 83 00:02:53,670 --> 00:02:51,760 and you can use them to find your 84 00:02:54,390 --> 00:02:53,680 bearings when looking skyward all year 85 00:02:55,830 --> 00:02:54,400 long 86 00:02:57,110 --> 00:02:55,840 [Music] 87 00:03:00,070 --> 00:02:57,120 here are the phases of the moon for 88 00:03:03,830 --> 00:03:01,830 stay up to date with all of nasa's 89 00:03:06,070 --> 00:03:03,840 missions to explore the solar system and 90 00:03:07,750 --> 00:03:06,080 beyond at nasa.gov 91 00:03:09,589 --> 00:03:07,760 i'm preston dykes from nasa's jet
