1 00:00:04,630 --> 00:00:02,550 [Music] 2 00:00:05,990 --> 00:00:04,640 what's up for august 3 00:00:07,670 --> 00:00:06,000 this month brings a bunch of 4 00:00:08,950 --> 00:00:07,680 opportunities to see the moon posing 5 00:00:12,549 --> 00:00:08,960 with the planets 6 00:00:14,390 --> 00:00:12,559 plus here come the meteors on august 1st 7 00:00:15,669 --> 00:00:14,400 the moon makes a lovely triangle with 8 00:00:18,150 --> 00:00:15,679 jupiter and saturn 9 00:00:20,310 --> 00:00:18,160 low in the southeast after sunset the 10 00:00:22,550 --> 00:00:20,320 trio is visible all night rising to its 11 00:00:23,750 --> 00:00:22,560 highest point in the south around 11 pm 12 00:00:25,269 --> 00:00:23,760 local time 13 00:00:27,429 --> 00:00:25,279 if you miss them there's another chance 14 00:00:29,269 --> 00:00:27,439 at the end of the month on august 28th 15 00:00:32,069 --> 00:00:29,279 as the moon swings back around in its 16 00:00:34,630 --> 00:00:32,079 orbit to join the planetary pair 17 00:00:37,030 --> 00:00:34,640 on august 9th mars will appear super 18 00:00:39,110 --> 00:00:37,040 close to the moon before dawn 19 00:00:40,630 --> 00:00:39,120 look toward the south high in the sky 20 00:00:42,229 --> 00:00:40,640 and you can't miss it 21 00:00:44,310 --> 00:00:42,239 mars is the bright reddish point of 22 00:00:45,670 --> 00:00:44,320 light just right of the moon 23 00:00:47,830 --> 00:00:45,680 weather permitting this should be a 24 00:00:50,069 --> 00:00:47,840 beautiful sky with the pleiades 25 00:00:51,830 --> 00:00:50,079 orion aldebaran and venus to the 26 00:00:53,590 --> 00:00:51,840 southeast 27 00:00:56,150 --> 00:00:53,600 on august 15th in the hour before 28 00:00:57,830 --> 00:00:56,160 sunrise look for venus in the east just 29 00:00:59,029 --> 00:00:57,840 a couple of finger widths apart from the 30 00:01:00,549 --> 00:00:59,039 crescent moon 31 00:01:02,549 --> 00:01:00,559 and if you take a look before the sky 32 00:01:04,390 --> 00:01:02,559 gets too bright you'll see the duo 33 00:01:06,469 --> 00:01:04,400 surrounded that morning by a ring of 34 00:01:08,950 --> 00:01:06,479 bright stars 35 00:01:10,950 --> 00:01:08,960 the annual perseid meteor shower peaks 36 00:01:12,630 --> 00:01:10,960 on the morning of august 12th 37 00:01:14,390 --> 00:01:12,640 the last quarter moon will interfere 38 00:01:15,990 --> 00:01:14,400 with the visibility of most fainter 39 00:01:17,429 --> 00:01:16,000 perseid meteors this year 40 00:01:19,270 --> 00:01:17,439 but you'll still be able to see a few 41 00:01:20,469 --> 00:01:19,280 brighter ones including the occasional 42 00:01:22,310 --> 00:01:20,479 fireball 43 00:01:23,830 --> 00:01:22,320 the best time to look is in the predawn 44 00:01:25,590 --> 00:01:23,840 hours of august 12th 45 00:01:27,429 --> 00:01:25,600 but midnight to dawn any morning the 46 00:01:28,710 --> 00:01:27,439 week before or after should produce a 47 00:01:30,870 --> 00:01:28,720 few meteors 48 00:01:32,550 --> 00:01:30,880 the perseids generally appear to radiate 49 00:01:33,510 --> 00:01:32,560 from a point high in the north called 50 00:01:34,950 --> 00:01:33,520 the radiant 51 00:01:37,109 --> 00:01:34,960 but you need only point yourself 52 00:01:39,270 --> 00:01:37,119 generally toward the north and look up 53 00:01:41,190 --> 00:01:39,280 and while we're talking meteors did you 54 00:01:44,310 --> 00:01:41,200 know many of these shooting stars 55 00:01:46,630 --> 00:01:44,320 come from comets most of the annual 56 00:01:48,789 --> 00:01:46,640 meteor showers we observe take place as 57 00:01:50,950 --> 00:01:48,799 earth passes through trails of debris 58 00:01:53,350 --> 00:01:50,960 left behind by active comets orbiting 59 00:01:55,670 --> 00:01:53,360 the sun casting off little bits of dusty 60 00:01:57,590 --> 00:01:55,680 debris in their long tails 61 00:01:58,789 --> 00:01:57,600 the perseid meteors come from a comet 62 00:02:02,230 --> 00:01:58,799 called swift tuttle 63 00:02:04,310 --> 00:02:02,240 which orbits the sun every 133 years 64 00:02:06,469 --> 00:02:04,320 in july a comet that was just discovered 65 00:02:08,790 --> 00:02:06,479 this spring by nasa's neowise mission 66 00:02:10,389 --> 00:02:08,800 made an appearance in our skies wowing 67 00:02:13,270 --> 00:02:10,399 observers on the ground 68 00:02:15,670 --> 00:02:13,280 and even in space this comet has a 69 00:02:16,309 --> 00:02:15,680 nearly 7 000 year orbit around the sun 70 00:02:18,070 --> 00:02:16,319 so 71 00:02:20,550 --> 00:02:18,080 it won't be back this way for a long 72 00:02:22,070 --> 00:02:20,560 time but it's possible that a meteor you 73 00:02:24,309 --> 00:02:22,080 see some night in the future 74 00:02:26,309 --> 00:02:24,319 might just be a little reminder of comet 75 00:02:27,670 --> 00:02:26,319 neowise 76 00:02:30,390 --> 00:02:27,680 here are the phases of the moon for 77 00:02:34,070 --> 00:02:32,150 you can catch up on all of nasa's 78 00:02:36,869 --> 00:02:34,080 missions to explore the solar system and 79 00:02:38,390 --> 00:02:36,879 beyond at nasa.gov 80 00:02:40,150 --> 00:02:38,400 i'm preston dykes from nasa's jet
