1 00:00:04,309 --> 00:00:02,550 [Music] 2 00:00:07,430 --> 00:00:04,319 what's up for august 3 00:00:08,230 --> 00:00:07,440 prime time for the perseids jupiter and 4 00:00:10,870 --> 00:00:08,240 saturn at 5 00:00:11,350 --> 00:00:10,880 opposition and why the third moon of the 6 00:00:13,830 --> 00:00:11,360 season 7 00:00:16,230 --> 00:00:13,840 is kind of special august brings the 8 00:00:17,349 --> 00:00:16,240 best-known meteor shower of the year the 9 00:00:19,590 --> 00:00:17,359 perseids 10 00:00:21,830 --> 00:00:19,600 this annual meteor shower happens each 11 00:00:23,750 --> 00:00:21,840 year as earth crosses the debris trail 12 00:00:26,150 --> 00:00:23,760 of comet swift tuttle 13 00:00:27,509 --> 00:00:26,160 most of these meteors are grains of dust 14 00:00:29,830 --> 00:00:27,519 up to the size of a pea 15 00:00:32,470 --> 00:00:29,840 and they create fabulous shooting stars 16 00:00:33,990 --> 00:00:32,480 as they burn up in earth's atmosphere 17 00:00:35,910 --> 00:00:34,000 although perseids can be seen from 18 00:00:37,990 --> 00:00:35,920 mid-july through late august the most 19 00:00:39,750 --> 00:00:38,000 likely time to see any meteors is a 20 00:00:40,950 --> 00:00:39,760 couple of days on either side of the 21 00:00:44,630 --> 00:00:40,960 peak 22 00:00:46,069 --> 00:00:44,640 august 11th and into the pre-dawn hours 23 00:00:47,590 --> 00:00:46,079 of august 12th 24 00:00:50,470 --> 00:00:47,600 think of that as prime time for the 25 00:00:52,389 --> 00:00:50,480 perseids under really dark skies you 26 00:00:54,310 --> 00:00:52,399 could see almost one per minute near the 27 00:00:56,150 --> 00:00:54,320 time of maximum activity 28 00:00:57,750 --> 00:00:56,160 this year's peak night for the perseids 29 00:00:59,510 --> 00:00:57,760 benefits from a moon that sets 30 00:01:01,430 --> 00:00:59,520 early in the evening so it won't 31 00:01:03,270 --> 00:01:01,440 interfere with the faint meteors 32 00:01:05,270 --> 00:01:03,280 but before it sets that evening be sure 33 00:01:07,270 --> 00:01:05,280 to check out that gorgeous crescent moon 34 00:01:08,630 --> 00:01:07,280 in the west after sunset with brilliant 35 00:01:10,789 --> 00:01:08,640 planet venus 36 00:01:11,990 --> 00:01:10,799 to enjoy the perseid meteor shower just 37 00:01:14,870 --> 00:01:12,000 find a safe dark 38 00:01:16,630 --> 00:01:14,880 location away from bright city lights 39 00:01:18,230 --> 00:01:16,640 lie down or recline with your feet 40 00:01:20,789 --> 00:01:18,240 facing roughly toward the north 41 00:01:22,390 --> 00:01:20,799 and look up the meteors appear to 42 00:01:24,149 --> 00:01:22,400 radiate from around the constellation 43 00:01:26,310 --> 00:01:24,159 perseus but they can streak across the 44 00:01:28,310 --> 00:01:26,320 sky anywhere above you 45 00:01:30,230 --> 00:01:28,320 nasa also has a way for you to catch 46 00:01:32,390 --> 00:01:30,240 some perseids online 47 00:01:34,630 --> 00:01:32,400 nasa's meteor watch team plans a live 48 00:01:36,069 --> 00:01:34,640 stream overnight on august 11th 49 00:01:38,069 --> 00:01:36,079 visit the link on screen for more 50 00:01:39,749 --> 00:01:38,079 details 51 00:01:42,389 --> 00:01:39,759 august is perhaps the best time this 52 00:01:44,230 --> 00:01:42,399 year to enjoy viewing jupiter and saturn 53 00:01:46,710 --> 00:01:44,240 as both planets reach opposition this 54 00:01:48,710 --> 00:01:46,720 month opposition is the term for when a 55 00:01:49,590 --> 00:01:48,720 planet is on the same side of the solar 56 00:01:51,910 --> 00:01:49,600 system as earth 57 00:01:54,069 --> 00:01:51,920 and directly opposite from the sun it 58 00:01:54,789 --> 00:01:54,079 happens each year as earth loops around 59 00:01:57,109 --> 00:01:54,799 in its orbit 60 00:01:58,550 --> 00:01:57,119 passing by the much slower moving gas 61 00:02:00,230 --> 00:01:58,560 giant planets 62 00:02:02,469 --> 00:02:00,240 around this time the planet is visible 63 00:02:04,950 --> 00:02:02,479 from sunset to sunrise and reaches its 64 00:02:06,950 --> 00:02:04,960 highest point in the sky around midnight 65 00:02:08,790 --> 00:02:06,960 opposition is also near the time when 66 00:02:10,229 --> 00:02:08,800 earth is closest to the planet so this 67 00:02:11,830 --> 00:02:10,239 is when the planet tends to look its 68 00:02:14,229 --> 00:02:11,840 biggest and brightest 69 00:02:14,869 --> 00:02:14,239 now opposition does technically have a 70 00:02:17,110 --> 00:02:14,879 precise 71 00:02:17,990 --> 00:02:17,120 moment when the sun earth and the planet 72 00:02:19,350 --> 00:02:18,000 line up 73 00:02:21,510 --> 00:02:19,360 but in practice it's better to think of 74 00:02:22,470 --> 00:02:21,520 it as a period of time usually about a 75 00:02:24,390 --> 00:02:22,480 month 76 00:02:25,830 --> 00:02:24,400 for saturn opposition takes place this 77 00:02:28,630 --> 00:02:25,840 year on august 2nd 78 00:02:30,790 --> 00:02:28,640 and for jupiter it's august 19th for the 79 00:02:31,670 --> 00:02:30,800 latest close-up views and discoveries 80 00:02:33,990 --> 00:02:31,680 from jupiter 81 00:02:35,990 --> 00:02:34,000 follow nasa's juno mission with nasa's 82 00:02:38,309 --> 00:02:36,000 solar system exploration website and 83 00:02:40,390 --> 00:02:38,319 social media 84 00:02:42,550 --> 00:02:40,400 as you're enjoying jupiter and saturn 85 00:02:43,270 --> 00:02:42,560 during august watch as the increasingly 86 00:02:45,350 --> 00:02:43,280 full moon 87 00:02:48,550 --> 00:02:45,360 slides beneath the pair of planets over 88 00:02:51,030 --> 00:02:48,560 several days from the 19th to the 22nd 89 00:02:53,509 --> 00:02:51,040 plus the full moon on august 22nd is 90 00:02:55,350 --> 00:02:53,519 what's known as a seasonal blue moon 91 00:02:57,270 --> 00:02:55,360 as it's the third full moon out of four 92 00:02:58,790 --> 00:02:57,280 this season where normally each season 93 00:03:00,229 --> 00:02:58,800 there are only three 94 00:03:01,990 --> 00:03:00,239 this happens every two and a half to 95 00:03:05,589 --> 00:03:02,000 three years or as they say 96 00:03:08,229 --> 00:03:05,599 once in a blue moon here are the phases 97 00:03:10,070 --> 00:03:08,239 of the moon for august 98 00:03:12,229 --> 00:03:10,080 you can catch up on all of nasa's 99 00:03:12,869 --> 00:03:12,239 missions to explore the solar system and 100 00:03:15,589 --> 00:03:12,879 beyond 101 00:03:17,270 --> 00:03:15,599 at nasa.gov i'm preston dykes from
