1 00:00:04,309 --> 00:00:02,470 [Music] 2 00:00:06,309 --> 00:00:04,319 what's up for june 3 00:00:08,070 --> 00:00:06,319 a planetary breakup 4 00:00:11,669 --> 00:00:08,080 prime viewing for a well-known star 5 00:00:13,990 --> 00:00:11,679 cluster and the constellation lyra 6 00:00:15,589 --> 00:00:14,000 the gathering of four naked eye planets 7 00:00:17,349 --> 00:00:15,599 we've been enjoying in the morning sky 8 00:00:19,670 --> 00:00:17,359 for the past few months including 9 00:00:21,189 --> 00:00:19,680 several close conjunctions is beginning 10 00:00:23,990 --> 00:00:21,199 to break up 11 00:00:25,750 --> 00:00:24,000 over the next few months saturn mars 12 00:00:27,589 --> 00:00:25,760 jupiter and venus will appear 13 00:00:30,230 --> 00:00:27,599 increasingly spread out across the 14 00:00:32,150 --> 00:00:30,240 morning sky so much so that venus and 15 00:00:35,030 --> 00:00:32,160 saturn will make their exits as morning 16 00:00:37,270 --> 00:00:35,040 objects for most observers by september 17 00:00:39,510 --> 00:00:37,280 look for this increasingly spaced out 18 00:00:41,270 --> 00:00:39,520 planetary procession in june and note 19 00:00:44,709 --> 00:00:41,280 that the crescent moon jumps into the 20 00:00:46,549 --> 00:00:44,719 lineup on the morning of the 23rd 21 00:00:49,270 --> 00:00:46,559 june is an excellent time to observe one 22 00:00:53,510 --> 00:00:49,280 of the best known globular star clusters 23 00:00:55,590 --> 00:00:53,520 m13 also known as the hercules cluster 24 00:00:57,670 --> 00:00:55,600 globular clusters are spherical 25 00:00:59,349 --> 00:00:57,680 collections of stars tightly packed 26 00:01:01,830 --> 00:00:59,359 together in their centers 27 00:01:03,430 --> 00:01:01,840 m13 itself contains several hundred 28 00:01:06,789 --> 00:01:03,440 thousand stars 29 00:01:08,710 --> 00:01:06,799 globular clusters are also extremely old 30 00:01:11,030 --> 00:01:08,720 the stars in m13 are thought to be 31 00:01:13,030 --> 00:01:11,040 around 12 billion years old which is 32 00:01:14,469 --> 00:01:13,040 approaching the age of the universe 33 00:01:16,469 --> 00:01:14,479 itself 34 00:01:19,270 --> 00:01:16,479 our home galaxy the milky way is known 35 00:01:21,670 --> 00:01:19,280 to have about 150 globular clusters they 36 00:01:23,429 --> 00:01:21,680 orbit outside the galaxy's disk 37 00:01:25,350 --> 00:01:23,439 traveling tens of thousands of light 38 00:01:27,190 --> 00:01:25,360 years above and below its spiral arms 39 00:01:28,870 --> 00:01:27,200 and most of its stars 40 00:01:30,710 --> 00:01:28,880 now the hercules cluster is best 41 00:01:32,630 --> 00:01:30,720 observed with a telescope and larger 42 00:01:34,950 --> 00:01:32,640 telescopes will allow you to see more of 43 00:01:36,630 --> 00:01:34,960 the cluster's stars but you can also 44 00:01:45,590 --> 00:01:36,640 find it with a pair of binoculars where 45 00:01:49,910 --> 00:01:48,310 find m13 in the constellation hercules 46 00:01:52,310 --> 00:01:49,920 which is high in the east in the first 47 00:01:54,710 --> 00:01:52,320 couple of hours after dark in june 48 00:01:55,990 --> 00:01:54,720 first look for the bright stars vega and 49 00:01:57,910 --> 00:01:56,000 arcturus 50 00:01:59,910 --> 00:01:57,920 then find the four stars that comprise 51 00:02:02,069 --> 00:01:59,920 the keystone which is the pattern making 52 00:02:04,069 --> 00:02:02,079 up the central part of hercules 53 00:02:06,230 --> 00:02:04,079 you'll find m13 about a third of the way 54 00:02:08,710 --> 00:02:06,240 between the two stars on the western or 55 00:02:10,869 --> 00:02:08,720 leading side of the keystone 56 00:02:13,750 --> 00:02:10,879 so check out the great globular cluster 57 00:02:15,910 --> 00:02:13,760 in hercules m13 in june and find 58 00:02:18,229 --> 00:02:15,920 yourself staring at an ancient gathering 59 00:02:20,869 --> 00:02:18,239 of stars that soars high above the milky 60 00:02:25,110 --> 00:02:23,110 finally in june a quick introduction to 61 00:02:27,670 --> 00:02:25,120 one of the smaller constellations that's 62 00:02:30,150 --> 00:02:27,680 home to one of the brightest stars 63 00:02:33,190 --> 00:02:30,160 that's the constellation lyra 64 00:02:36,150 --> 00:02:33,200 it represents a liar or harp played by 65 00:02:38,070 --> 00:02:36,160 the musician orpheus in greek mythology 66 00:02:40,229 --> 00:02:38,080 in arab cultures as well as ancient 67 00:02:41,270 --> 00:02:40,239 egypt and india lyra was seen as an 68 00:02:43,990 --> 00:02:41,280 eagle 69 00:02:45,589 --> 00:02:44,000 and the inca of south america saw it as 70 00:02:48,070 --> 00:02:45,599 a llama 71 00:02:49,670 --> 00:02:48,080 find lyra by looking for vega which is 72 00:02:51,750 --> 00:02:49,680 the westernmost of the three bright 73 00:02:53,190 --> 00:02:51,760 stars in the summer triangle 74 00:02:54,790 --> 00:02:53,200 in the northern hemisphere you'll find 75 00:02:57,589 --> 00:02:54,800 it halfway up the eastern sky in the 76 00:02:59,910 --> 00:02:57,599 first couple of hours after dark in june 77 00:03:00,869 --> 00:02:59,920 vega is by far the brightest star in 78 00:03:02,949 --> 00:03:00,879 lyra 79 00:03:04,390 --> 00:03:02,959 it's the fifth brightest star in the sky 80 00:03:06,710 --> 00:03:04,400 and the second brightest in the northern 81 00:03:08,229 --> 00:03:06,720 hemisphere after sirius 82 00:03:10,149 --> 00:03:08,239 a pair of binoculars will help you see 83 00:03:12,630 --> 00:03:10,159 the other stars in lyra which form a 84 00:03:14,229 --> 00:03:12,640 sort of parallelogram hanging beneath it 85 00:03:16,830 --> 00:03:14,239 it's sometimes described as looking a 86 00:03:19,910 --> 00:03:16,840 bit like a diamond ring with vega as the 87 00:03:22,390 --> 00:03:19,920 diamond and that's not the only ring in 88 00:03:24,869 --> 00:03:22,400 lyra it's also home to the famous ring 89 00:03:27,030 --> 00:03:24,879 nebula where a star has blown off most 90 00:03:30,070 --> 00:03:27,040 of its outer layers leaving behind a 91 00:03:32,630 --> 00:03:30,080 remnant star known as a white dwarf 92 00:03:34,869 --> 00:03:32,640 so let the bright star vega lead you to 93 00:03:35,750 --> 00:03:34,879 lyra the harp constellation in the june 94 00:03:37,750 --> 00:03:35,760 sky 95 00:03:40,070 --> 00:03:37,760 and if you see it as an eagle or a 96 00:03:42,949 --> 00:03:40,080 diamond ring or a llama well that's 97 00:03:47,030 --> 00:03:42,959 perfectly okay too 98 00:03:48,630 --> 00:03:47,040 here are the phases of the moon for june 99 00:03:50,550 --> 00:03:48,640 stay up to date with all of nasa's 100 00:03:53,350 --> 00:03:50,560 missions to explore the solar system and 101 00:03:54,869 --> 00:03:53,360 beyond at nasa.gov 102 00:03:56,710 --> 00:03:54,879 i'm preston dykes from nasa's jet
