WEBVTT 00:01.270 --> 00:20.520 web 00:20.520 --> 00:22.770 supermoon not so much 00:22.770 --> 00:26.980 hey there stargazers and in re guess astronomer from the Cincinnati 00:26.980 --> 00:27.900 Observatory 00:27.900 --> 00:32.870 don't look now but we've got another super moon coming on August 10 00:32.870 --> 00:36.680 and I James Aubrey director the key cassava pop planetarium in Gainesville 00:36.680 --> 00:37.260 Florida 00:37.260 --> 00:42.160 don't let the supermoon get to you because it's not really that big a deal 00:42.160 --> 00:47.040 I'll come on James all the TV news people go nuts about the supermoon 00:47.040 --> 00:50.430 so it must be something really special right Dean 00:50.430 --> 00:54.320 you know as well as I do that even though there is a measurable size 00:54.320 --> 00:57.309 difference between the biggest and smallest full moon of the year 00:57.309 --> 01:00.620 you can't really notice it without special measuring devices 01:00.620 --> 01:04.790 pay I have an idea but to tell everybody about one of the simplest 01:04.790 --> 01:08.289 most handy measuring devices around okay 01:08.289 --> 01:11.789 everyone already has one right at hand but 01:11.789 --> 01:16.880 we need a really catchy time for but combined our names in college the 01:16.880 --> 01:19.908 reg all barry noon sizer 01:19.908 --> 01:23.580 now I think I prefer the our gas moon a meter 01:23.580 --> 01:27.590 is maybe not after all we're talking about using your pinkie finger 01:27.590 --> 01:30.940 to see how big does supermoon is not 01:30.940 --> 01:35.000 the moon is the easiest thing to see in the night sky but remember when you're 01:35.000 --> 01:37.750 looking at the moon you're seen reflected sunlight 01:37.750 --> 01:42.479 the moon does not produce light up and the moon is not always the stargazers 01:42.479 --> 01:44.100 friend because they can 01:44.100 --> 01:48.190 get to be so bright it wipes out most to the stars and the Milky Way 01:48.190 --> 01:51.470 let's start watching the moon on the evening of August 4th 01:51.470 --> 01:55.180 and see what we can see and use your pinky finger to measure the apparent 01:55.180 --> 01:56.009 size amor 01:56.009 --> 01:59.039 extend your arm stick a pinky finger 01:59.039 --> 02:02.159 close one eye and then put your pinky finger over the moon 02:02.159 --> 02:07.010 it will disappear behind your finger the moon will be one day pass first quarter 02:07.010 --> 02:11.390 so it's what we call a waxing gibbous moon remember give this means hopped 02:11.390 --> 02:16.019 and waxing means it'll get bigger night after night to the moon's left is the 02:16.019 --> 02:18.379 biggest and brightest constellation of summer 02:18.379 --> 02:22.970 Scorpius the Scorpion these three stars mark the head of the Scorpion 02:22.970 --> 02:26.400 and follow this curving line stars down and around 02:26.400 --> 02:29.690 to the parent stars that marked the stinger at the end of the tail 02:29.690 --> 02:33.420 the next night a slightly fatter moon will be above bright 02:33.420 --> 02:37.910 red and Taris which marks the heart of the Scorpion remember to use your pinky 02:37.910 --> 02:38.350 finger 02:38.350 --> 02:42.720 to measure the moon and Tyrese is one of the largest stars no 02:42.720 --> 02:47.329 and it were placed where our son is it would extend out be on mars 02:47.329 --> 02:51.209 and Tories produces over sixty thousand times as much 02:51.209 --> 02:54.360 energy is our son who 02:54.360 --> 02:58.230 the next two nights the sixth and seventh even fatter moon will be about 02:58.230 --> 02:59.870 the stars have said Terry its 02:59.870 --> 03:04.340 the Centaur that follows the Scorpion across the sky but with the extra white 03:04.340 --> 03:05.450 the moon is reflecting 03:05.450 --> 03:09.890 he'll do well to spot but teapot stars that make up just part of secretaries 03:09.890 --> 03:14.280 the next two nights the 8 and the night the moon will continue to get fatter 03:14.280 --> 03:19.349 try your finger trick see what happens the moon is now in the constellation of 03:19.349 --> 03:20.489 Kappa cornice 03:20.489 --> 03:24.120 just barely and though it's not quite for now 03:24.120 --> 03:28.660 it will probably look forward to most people but I won't really be full 03:28.660 --> 03:32.110 until 2009 p.m. Eastern Time on the tech 03:32.110 --> 03:35.970 we won't get to see the moon until rises several hours later 03:35.970 --> 03:40.480 so if you really want to be picky about it the moon is passed ball when it rises 03:40.480 --> 03:42.040 for us in North America 03:42.040 --> 03:46.319 so what makes this full moon a supposedly supermoon 03:46.319 --> 03:49.549 supermoon is not really an astronomical term 03:49.549 --> 03:53.760 refers to a moon that is for at about the same time it's especially close to 03:53.760 --> 03:55.200 the air 03:55.200 --> 03:59.010 the moon's orbit is not a perfect circle but is really an ellipse 03:59.010 --> 04:02.190 this means the moon gets closer to the earth paris je 04:02.190 --> 04:05.260 once every orbit and for this from the earth Apogee 04:05.260 --> 04:08.270 once every orbit in fact this year the moon had 04:08.270 --> 04:11.610 to paris je is in January and will have two more 04:11.610 --> 04:14.690 in November but this pair G on August 10 04:14.690 --> 04:17.810 is only nine minutes away from the time the moon is full 04:17.810 --> 04:23.650 so it gives us the closest and of biggest full moon Cup 2014 04:23.650 --> 04:28.040 so look at the rising moon on the evening of August 10 and use your pinky 04:28.040 --> 04:30.280 finger to measure it can you tell it's a 04:30.280 --> 04:54.130 supermoon keep looking up 04:54.130 --> 04:59.130 me
