1 00:00:10,390 --> 00:00:06,470 the 2012 perseid meteor shower 2 00:00:12,390 --> 00:00:10,400 presented by science at nasa 3 00:00:15,270 --> 00:00:12,400 on the nights of august 11th through 4 00:00:17,269 --> 00:00:15,280 13th the best meteor shower of the year 5 00:00:18,950 --> 00:00:17,279 will fill pre-dawn skies with hundreds 6 00:00:21,670 --> 00:00:18,960 of shooting stars 7 00:00:23,269 --> 00:00:21,680 and that's just for starters 8 00:00:25,269 --> 00:00:23,279 the brightest planets in the solar 9 00:00:27,189 --> 00:00:25,279 system are lining up right in the middle 10 00:00:29,189 --> 00:00:27,199 of the display 11 00:00:31,830 --> 00:00:29,199 the perseid meteor shower peaks on the 12 00:00:33,590 --> 00:00:31,840 nights around august 12 as earth passes 13 00:00:35,430 --> 00:00:33,600 through a stream of debris from comet 14 00:00:37,590 --> 00:00:35,440 swift tuttle 15 00:00:39,750 --> 00:00:37,600 we expect to see meteor rates as high as 16 00:00:42,470 --> 00:00:39,760 a hundred per hour says bill cook of 17 00:00:45,990 --> 00:00:42,480 nasa's meteoroid environment office 18 00:00:48,470 --> 00:00:46,000 the perseids always put on a good show 19 00:00:49,910 --> 00:00:48,480 perseids can be seen any time after 10 20 00:00:51,830 --> 00:00:49,920 to 11 pm 21 00:00:55,189 --> 00:00:51,840 the best time to look however is during 22 00:00:56,869 --> 00:00:55,199 the dark hours immediately before dawn 23 00:00:59,349 --> 00:00:56,879 also advises cook 24 00:01:01,270 --> 00:00:59,359 avoid city lights if possible 25 00:01:02,869 --> 00:01:01,280 faint meteors are easily lost in the 26 00:01:04,549 --> 00:01:02,879 urban glare 27 00:01:06,390 --> 00:01:04,559 a visit to the countryside will 28 00:01:08,469 --> 00:01:06,400 typically triple the number of meteors 29 00:01:10,550 --> 00:01:08,479 you see 30 00:01:12,630 --> 00:01:10,560 this year's display is extra special 31 00:01:15,749 --> 00:01:12,640 because of the planets 32 00:01:17,590 --> 00:01:15,759 jupiter venus and the crescent moon are 33 00:01:20,310 --> 00:01:17,600 gathering together just as the perseid 34 00:01:22,310 --> 00:01:20,320 meteor shower reaches its peak 35 00:01:24,469 --> 00:01:22,320 the alignment occurs in the eastern sky 36 00:01:27,510 --> 00:01:24,479 before sunrise on the three mornings of 37 00:01:30,870 --> 00:01:27,520 highest meteor activity 38 00:01:33,270 --> 00:01:30,880 on august 11th a 33 crescent moon will 39 00:01:35,190 --> 00:01:33,280 glide by jupiter temporarily forming a 40 00:01:36,469 --> 00:01:35,200 bright pair directly above brilliant 41 00:01:38,550 --> 00:01:36,479 venus 42 00:01:40,710 --> 00:01:38,560 red giant star aldebaran will be there 43 00:01:42,310 --> 00:01:40,720 too adding a splash of color to the 44 00:01:45,510 --> 00:01:42,320 gathering 45 00:01:47,429 --> 00:01:45,520 on august 12th the narrowing 24 crescent 46 00:01:48,789 --> 00:01:47,439 moon will drop down between jupiter and 47 00:01:51,030 --> 00:01:48,799 venus 48 00:01:52,389 --> 00:01:51,040 together they make a bright three-point 49 00:01:55,830 --> 00:01:52,399 line in the sky 50 00:01:58,230 --> 00:01:55,840 frequently bisected by shooting stars 51 00:01:59,510 --> 00:01:58,240 on august 13th with the shower just 52 00:02:02,469 --> 00:01:59,520 beginning to wane 53 00:02:05,429 --> 00:02:02,479 the planets put on their best show yet 54 00:02:07,510 --> 00:02:05,439 the 17 crescent moon will pass less than 55 00:02:09,990 --> 00:02:07,520 three degrees from venus as jupiter 56 00:02:11,910 --> 00:02:10,000 hovers overhead 57 00:02:13,510 --> 00:02:11,920 skywatchers say there's nothing prettier 58 00:02:16,309 --> 00:02:13,520 than a close encounter between the 59 00:02:18,470 --> 00:02:16,319 slender crescent moon and venus 60 00:02:19,270 --> 00:02:18,480 nothing that is except for the crescent 61 00:02:20,229 --> 00:02:19,280 moon 62 00:02:23,110 --> 00:02:20,239 venus 63 00:02:24,790 --> 00:02:23,120 and a flurry of perseids 64 00:02:26,710 --> 00:02:24,800 it's only natural while you're watching 65 00:02:28,229 --> 00:02:26,720 a meteor shower like the perseids to 66 00:02:29,270 --> 00:02:28,239 count the number of shooting stars you 67 00:02:30,949 --> 00:02:29,280 see 68 00:02:32,229 --> 00:02:30,959 it turns out those numbers in your head 69 00:02:33,990 --> 00:02:32,239 are valuable 70 00:02:35,670 --> 00:02:34,000 nasa wants them 71 00:02:37,509 --> 00:02:35,680 meteor tallies gathered by amateur 72 00:02:39,670 --> 00:02:37,519 skywatchers can be used by nasa's 73 00:02:42,390 --> 00:02:39,680 meteoroid environment office to study 74 00:02:44,390 --> 00:02:42,400 and model the perseid debris stream 75 00:02:46,710 --> 00:02:44,400 we've developed an app for android and 76 00:02:49,190 --> 00:02:46,720 iphones to help amateur skywatchers 77 00:02:51,830 --> 00:02:49,200 count meteors in a scientific way and 78 00:02:53,750 --> 00:02:51,840 report the results to us says cook 79 00:02:55,589 --> 00:02:53,760 it's called the meteor counter and it's 80 00:02:58,790 --> 00:02:55,599 available for free in the android 81 00:03:00,229 --> 00:02:58,800 marketplace and apple's app store 82 00:03:03,190 --> 00:03:00,239 whether you're counting meteors for 83 00:03:05,350 --> 00:03:03,200 science or just watching them for fun 84 00:03:07,670 --> 00:03:05,360 this is a must-see event 85 00:03:09,509 --> 00:03:07,680 enjoy the show 86 00:03:11,030 --> 00:03:09,519 for more news about the night sky and
