WEBVTT FILE 1 00:00:00.010 --> 00:00:03.020 Coming up on November 14 is 2 00:00:03.020 --> 00:00:06.020 a supermoon, the closest moon to Earth since 1948. 3 00:00:06.020 --> 00:00:09.210 Here to tell us a little bit about it is Dr. Alex Young. 4 00:00:09.210 --> 00:00:14.220 So what is a supermoon and what this one so super? 5 00:00:14.220 --> 00:00:19.410 Well a supermoon is what happens when the moon is 6 00:00:19.410 --> 00:00:24.590 within 90% closest approach as it orbits the Earth 7 00:00:24.590 --> 00:00:29.600 also a full moon and this one is extra special because 8 00:00:29.600 --> 00:00:32.620 it is the closest approach we've had during 9 00:00:32.620 --> 00:00:36.810 a full moon since 1948. 10 00:00:36.810 --> 00:00:39.830 When is the best time to see the supermoon 11 00:00:39.830 --> 00:00:43.840 and will it look different from other full moons? 12 00:00:43.840 --> 00:00:45.860 Well you can go out on Saturday night, 13 00:00:45.860 --> 00:00:47.880 Sunday night or Monday night 14 00:00:47.880 --> 00:00:49.890 and as long as there is a clear sky 15 00:00:49.890 --> 00:00:51.890 when the moon is up 16 00:00:51.890 --> 00:00:54.090 you're going to get to see a moon 17 00:00:54.090 --> 00:00:58.100 that's 14% bigger and 30% brighter. 18 00:00:58.100 --> 00:01:02.290 So it's going to give everyone a spectacular show. 19 00:01:02.290 --> 00:01:06.310 Many of our viewers will be amazed to hear that NASA 20 00:01:06.310 --> 00:01:09.330 has had a spacecraft orbiting over 7 years. 21 00:01:09.330 --> 00:01:12.360 What's the most surprising thing you've seen? 22 00:01:12.360 --> 00:01:15.370 So over the past 7 years 23 00:01:15.370 --> 00:01:18.400 NASA's Lunar Reconnaissance Orbiter (LRO) 24 00:01:18.400 --> 00:01:21.410 has been orbiting the moon giving us a spectacular 25 00:01:21.410 --> 00:01:24.470 view, mapping the surface, 26 00:01:24.470 --> 00:01:26.650 showing it's impact craters 27 00:01:26.650 --> 00:01:28.660 telling us an awful lot about 28 00:01:28.660 --> 00:01:30.680 how the moon was formed and how its evolved 29 00:01:30.680 --> 00:01:32.700 over time. But one of things 30 00:01:32.700 --> 00:01:34.710 that's been so amazing is we've come 31 00:01:34.710 --> 00:01:36.720 to find how much the moon is changing. 32 00:01:36.720 --> 00:01:38.900 That is the surface is being 33 00:01:38.900 --> 00:01:41.090 bombarded much more then we ever 34 00:01:41.090 --> 00:01:44.120 expected over such a short period of time. 35 00:01:44.120 --> 00:01:47.300 So we have seen how much the moon is changing and how dynamic 36 00:01:47.300 --> 00:01:50.320 of a place it really is. 37 00:01:50.320 --> 00:01:53.380 What can our moon teach us about other mysterious places 38 00:01:53.380 --> 00:01:56.400 deeper in the solar system? 39 00:01:56.400 --> 00:01:59.410 Studying the moon serves as a 40 00:01:59.410 --> 00:02:02.420 way to compare with other objects 41 00:02:02.420 --> 00:02:04.430 in the solar system. 42 00:02:04.430 --> 00:02:06.450 So for example the New Horizons 43 00:02:06.450 --> 00:02:08.460 mission has sent back pictures 44 00:02:08.460 --> 00:02:10.470 of Pluto and what we've found 45 00:02:10.470 --> 00:02:12.490 is that it's much different then 46 00:02:12.490 --> 00:02:14.510 we expected. We didn't see 47 00:02:14.510 --> 00:02:16.520 the impact craters that we thought we were 48 00:02:16.520 --> 00:02:18.530 going to see. 49 00:02:18.530 --> 00:02:20.540 Like we expect comparing it to the moon 50 00:02:20.540 --> 00:02:22.710 so this is telling us that the environment 51 00:02:22.710 --> 00:02:24.720 is much different 52 00:02:24.720 --> 00:02:26.900 and the planet 53 00:02:26.900 --> 00:02:29.090 itself is changing in 54 00:02:29.090 --> 00:02:32.270 evolving that we never expected. 55 00:02:32.270 --> 00:02:35.470 Where can we learn more? 56 00:02:35.470 --> 00:02:39.480 Go to nasa.gov/lro 57 00:02:39.480 --> 00:02:43.500 to see more about the LRO mission and 58 00:02:43.500 --> 00:02:46.520 studying the moon and the solar system 59 00:02:46.520 --> 00:02:48.550 and if you take pictures of the supermoon 60 00:02:48.550 --> 00:02:50.580 share them on social media 61 00:02:50.580 --> 00:02:53.770 with #NASAsupermoon 62 00:02:53.770 --> 00:02:54.452
