1 00:00:04,630 --> 00:00:02,629 [Music] 2 00:00:07,430 --> 00:00:04,640 what's up for may 3 00:00:07,990 --> 00:00:07,440 this month a rocky planet roundup and a 4 00:00:11,270 --> 00:00:08,000 super 5 00:00:13,749 --> 00:00:11,280 blood moon eclipse 6 00:00:15,669 --> 00:00:13,759 beginning mid-may if you can find a 7 00:00:17,670 --> 00:00:15,679 clear view toward the western horizon 8 00:00:18,070 --> 00:00:17,680 you'll have an opportunity to see all 9 00:00:20,230 --> 00:00:18,080 four 10 00:00:21,670 --> 00:00:20,240 of the rocky inner planets of our solar 11 00:00:24,150 --> 00:00:21,680 system at the same time 12 00:00:24,790 --> 00:00:24,160 with your own eyes starting around may 13 00:00:26,790 --> 00:00:24,800 14th 14 00:00:28,550 --> 00:00:26,800 cast your gaze to the west about half an 15 00:00:31,509 --> 00:00:28,560 hour after sunset local time 16 00:00:32,229 --> 00:00:31,519 to see if you can spot mercury venus and 17 00:00:35,110 --> 00:00:32,239 mars 18 00:00:35,670 --> 00:00:35,120 and well earth is kind of hard to miss 19 00:00:37,270 --> 00:00:35,680 to see 20 00:00:39,590 --> 00:00:37,280 near the horizon you need an 21 00:00:40,790 --> 00:00:39,600 unobstructed view free of nearby trees 22 00:00:42,630 --> 00:00:40,800 and buildings 23 00:00:44,630 --> 00:00:42,640 some of the best places for this are the 24 00:00:47,029 --> 00:00:44,640 shores of lakes or the beach 25 00:00:48,229 --> 00:00:47,039 open plains or high up on a mountain or 26 00:00:49,910 --> 00:00:48,239 tall building 27 00:00:51,350 --> 00:00:49,920 in addition to the planet from around 28 00:00:53,189 --> 00:00:51,360 the 14th through the 17th 29 00:00:55,430 --> 00:00:53,199 the crescent moon joins the party for a 30 00:00:58,150 --> 00:00:55,440 lovely planetary tableau 31 00:00:59,830 --> 00:00:58,160 now venus will be really low in the sky 32 00:01:01,029 --> 00:00:59,840 it'll be easier to observe on its own 33 00:01:02,709 --> 00:01:01,039 later in the summer 34 00:01:04,710 --> 00:01:02,719 but for now take advantage of this 35 00:01:07,910 --> 00:01:04,720 opportunity to observe all of the inner 36 00:01:11,670 --> 00:01:07,920 planets in a single view 37 00:01:13,990 --> 00:01:11,680 may 26th brings a total lunar eclipse 38 00:01:15,429 --> 00:01:14,000 over several hours the moon will pass 39 00:01:17,590 --> 00:01:15,439 through earth's shadow 40 00:01:19,030 --> 00:01:17,600 causing it to darken and usually become 41 00:01:20,870 --> 00:01:19,040 reddish in color 42 00:01:22,789 --> 00:01:20,880 the red color comes from sunlight 43 00:01:24,469 --> 00:01:22,799 filtering through earth's atmosphere a 44 00:01:26,469 --> 00:01:24,479 ring of light created by all the 45 00:01:28,070 --> 00:01:26,479 sunrises and sunsets happening around 46 00:01:29,990 --> 00:01:28,080 our planet at that time 47 00:01:31,510 --> 00:01:30,000 because of the reddish color a lunar 48 00:01:34,789 --> 00:01:31,520 eclipse is often called 49 00:01:35,910 --> 00:01:34,799 a blood moon just how red it will look 50 00:01:37,749 --> 00:01:35,920 is hard to predict 51 00:01:39,510 --> 00:01:37,759 but dust in the atmosphere can have an 52 00:01:40,469 --> 00:01:39,520 effect and keep in mind there have been 53 00:01:43,190 --> 00:01:40,479 a couple of prominent 54 00:01:45,030 --> 00:01:43,200 volcanic eruptions recently lunar 55 00:01:46,950 --> 00:01:45,040 eclipses take place when the moon is 56 00:01:48,789 --> 00:01:46,960 full and this full moon happens when the 57 00:01:49,749 --> 00:01:48,799 moon is also near the closest point to 58 00:01:53,030 --> 00:01:49,759 earth in its orbit 59 00:01:55,030 --> 00:01:53,040 often called a super moon unlike solar 60 00:01:56,870 --> 00:01:55,040 eclipses which you should never look at 61 00:01:58,469 --> 00:01:56,880 it's safe to view lunar eclipses with 62 00:02:00,550 --> 00:01:58,479 your eyes and 63 00:02:02,230 --> 00:02:00,560 unlike solar eclipses which tend to have 64 00:02:03,830 --> 00:02:02,240 a narrower viewing path 65 00:02:05,590 --> 00:02:03,840 lunar eclipses are at least partly 66 00:02:06,709 --> 00:02:05,600 visible from anywhere on the planet's 67 00:02:08,630 --> 00:02:06,719 night side 68 00:02:10,630 --> 00:02:08,640 now eclipses happen at the same moment 69 00:02:12,470 --> 00:02:10,640 no matter where you are on earth but the 70 00:02:13,510 --> 00:02:12,480 time your clock reads during the eclipse 71 00:02:15,670 --> 00:02:13,520 depends of course 72 00:02:17,910 --> 00:02:15,680 on your time zone the best viewing for 73 00:02:19,990 --> 00:02:17,920 this eclipse is in the pacific rim 74 00:02:21,430 --> 00:02:20,000 that's the western parts of the americas 75 00:02:24,229 --> 00:02:21,440 australia and new zealand 76 00:02:25,670 --> 00:02:24,239 and eastern asia for the u.s the best 77 00:02:28,470 --> 00:02:25,680 viewing will be in hawaii 78 00:02:29,430 --> 00:02:28,480 alaska and the western states for the 79 00:02:31,430 --> 00:02:29,440 eastern u.s 80 00:02:32,470 --> 00:02:31,440 the eclipse begins for you during dawn 81 00:02:34,070 --> 00:02:32,480 twilight 82 00:02:35,750 --> 00:02:34,080 you may be able to observe the first 83 00:02:37,509 --> 00:02:35,760 part of the eclipse as the moon just 84 00:02:39,750 --> 00:02:37,519 starts to darken but the moon will be 85 00:02:41,430 --> 00:02:39,760 near or on the horizon as earth's shadow 86 00:02:43,190 --> 00:02:41,440 begins to cover it 87 00:02:44,790 --> 00:02:43,200 the farther west you are the more of the 88 00:02:46,869 --> 00:02:44,800 eclipse you'll be able to see before the 89 00:02:48,470 --> 00:02:46,879 moon sets that morning 90 00:02:50,229 --> 00:02:48,480 those in the western half of the country 91 00:02:53,030 --> 00:02:50,239 will be able to see almost the entire 92 00:02:53,589 --> 00:02:53,040 eclipse so if you're in the path of this 93 00:02:55,110 --> 00:02:53,599 eclipse 94 00:02:56,949 --> 00:02:55,120 check your local times for the best 95 00:02:58,869 --> 00:02:56,959 viewing near you and if you're in the 96 00:03:00,949 --> 00:02:58,879 u.s be prepared to get up early if you 97 00:03:05,110 --> 00:03:00,959 want to see this rare celestial event 98 00:03:09,270 --> 00:03:05,120 a super blood moon eclipse 99 00:03:12,949 --> 00:03:10,869 you can catch up on all of nasa's 100 00:03:15,110 --> 00:03:12,959 missions to explore the solar system and 101 00:03:16,630 --> 00:03:15,120 beyond at nasa.gov 102 00:03:18,470 --> 00:03:16,640 i'm
