WEBVTT 00:18.390 --> 00:22.560 season without Giants or time on the quiet sky 00:22.560 --> 00:27.500 greetings greetings fellow stargazers I'm james oberg director this Kika 00:27.500 --> 00:29.710 Silverpop planetarium in Gainesville Florida 00:29.710 --> 00:33.100 19 reas astronomer for the Cincinnati Observatory 00:33.100 --> 00:36.379 if you're one of those people who loves the change in seasons 00:36.379 --> 00:39.610 have you ever wondered whether the sky changes seasons to 00:39.610 --> 00:42.680 if so stick with us because and this episode 00:42.680 --> 00:46.500 will let you in on some other secrets at the season's and how you can 00:46.500 --> 00:50.120 double up your pleasure by not only watching the face of the earth change 00:50.120 --> 00:50.620 season 00:50.620 --> 00:54.250 but also by watching the face up the night sky change as well 00:54.250 --> 00:58.690 and will give you a heads up about a planet star rendezvous that happens 00:58.690 --> 01:02.989 only every other year let's show you EC 01:02.989 --> 01:07.340 all has to do with our Earth's yearly journey in its orbit around the Sun 01:07.340 --> 01:11.770 because as our earth orbits the Sun you'll see a slightly different part the 01:11.770 --> 01:12.810 starry sky 01:12.810 --> 01:17.509 each successive evening that is if you go outside every night after sunset for 01:17.509 --> 01:18.979 a year and look up 01:18.979 --> 01:22.940 you'll notice that the various constellations slowly but steadily shift 01:22.940 --> 01:24.940 their positions in the heavens a little bit 01:24.940 --> 01:29.440 West for each night a given star pattern will first appear low in the east 01:29.440 --> 01:33.619 and then gradually become very prominent and high up in early evening 01:33.619 --> 01:36.679 and then we'll continue that slow shift westward 01:36.679 --> 01:39.690 and then completely disappear from the heavens now 01:39.690 --> 01:43.240 when astronomers talk about sky seasons they mean that the particular star 01:43.240 --> 01:43.880 patterns 01:43.880 --> 01:48.420 or constellations %uh that season are those that are high above the horizon in 01:48.420 --> 01:52.450 early evening hours during a given season for instance 01:52.450 --> 01:55.479 and summer time we know that the great summer triangle 01:55.479 --> 01:59.729 and the giant scorpion are always very high and Dominic and early evening 01:59.729 --> 02:00.789 summer skies 02:00.789 --> 02:05.550 and in winter in early evening the giant a Ryan and his dog 02:05.550 --> 02:08.669 always ride high and dominate winters landscape 02:08.669 --> 02:12.050 springtime always has its wonderful Leo the Lion 02:12.050 --> 02:15.050 and the Big Dipper towering over head in early evening 02:15.050 --> 02:18.079 but there's one season when the sky becomes quiet 02:18.079 --> 02:21.209 a season when there are fewer bright stars visible than 02:21.209 --> 02:25.380 any other time of the year and quite appropriately I think that season is 02:25.380 --> 02:25.810 autumn 02:25.810 --> 02:29.430 the season when earth to is quieting down a season 02:29.430 --> 02:33.620 muted Sun and muted starlight a season without social Giants 02:33.620 --> 02:38.750 the season up the soft sky and if you do what I'm about to show you on 02:38.750 --> 02:42.909 at least one evening in autumn every autumn for the rest of your life 02:42.909 --> 02:47.459 your add yet another dimension to your enjoyment and the exquisite fields 02:47.459 --> 02:52.019 that autumn brings simply go outside any autumn evening just 02:52.019 --> 02:56.120 after the Sun has gone down and look for the Giants summer scorpion 02:56.120 --> 02:59.409 with his break reddish orange heart star Antares 02:59.409 --> 03:03.480 as they get ready to set low in the southwest this year 03:03.480 --> 03:06.530 there's an additional point and white just above Antares 03:06.530 --> 03:10.250 it's the reddish orange planet Mars which the Greeks named 03:10.250 --> 03:14.859 Aires their God of War it's commonly stated that the harder the Scorpion and 03:14.859 --> 03:15.469 Tyrese 03:15.469 --> 03:20.099 was named as the rival varies because they appear so much alike in the sky 03:20.099 --> 03:24.499 mars passes close to in Terry's roughly every two years 03:24.499 --> 03:28.530 because in Terry's lies just south on the path to the plants 03:28.530 --> 03:32.590 this coming Monday September 29 be sure to catch mars 03:32.590 --> 03:37.290 in a crescent moon in line with the in Terry's Mars will come back to alignment 03:37.290 --> 03:38.459 with the in Terry's in 03:38.459 --> 03:41.510 August up 20-16 and next time 03:41.510 --> 03:46.909 Saturn will be right there to make it even bet so be sure to get out and watch 03:46.909 --> 03:47.650 in Terry's 03:47.650 --> 03:51.340 mars and the moon next week watchin terry's Inmarsat 03:51.340 --> 03:54.819 as the evening goes along then in the hours before midnight 03:54.819 --> 03:58.810 you'll see for yourself the softer subscribers with a minimum a bright 03:58.810 --> 03:59.430 stars 03:59.430 --> 04:03.790 a time when you'll be able to delight in the exquisite beauty up to seven sisters 04:03.790 --> 04:04.349 rising 04:04.349 --> 04:09.659 then around midnight autumn skies will slowly give way to a preview of winter 04:09.659 --> 04:14.099 as a ride the winter giant boldly rises in the southeast 04:14.099 --> 04:18.488 how fitting how poetic at the sky seasons coincidentally match 04:18.488 --> 04:21.529 are Earth's as regular as clockwork 04:21.529 --> 04:26.010 yes every October of your life summer scorpion will set at sunset 04:26.010 --> 04:29.810 and wenches Orion mall eyes at midnight and hours in between 04:29.810 --> 04:32.980 will be the power to the slideshow impressions cell 04:32.980 --> 04:37.080 get outside under the heavens softly and remember to 04:37.080 --> 04:52.650 keep looking up 04:52.650 --> 04:57.650 well me
