1 00:00:18,390 --> 00:00:22,560 season without Giants or time on the quiet sky 2 00:00:22,560 --> 00:00:27,500 greetings greetings fellow stargazers I'm james oberg director this Kika 3 00:00:27,500 --> 00:00:29,710 Silverpop planetarium in Gainesville Florida 4 00:00:29,710 --> 00:00:33,100 19 reas astronomer for the Cincinnati Observatory 5 00:00:33,100 --> 00:00:36,379 if you're one of those people who loves the change in seasons 6 00:00:36,379 --> 00:00:39,610 have you ever wondered whether the sky changes seasons to 7 00:00:39,610 --> 00:00:42,680 if so stick with us because and this episode 8 00:00:42,680 --> 00:00:46,500 will let you in on some other secrets at the season's and how you can 9 00:00:46,500 --> 00:00:50,120 double up your pleasure by not only watching the face of the earth change 10 00:00:50,120 --> 00:00:50,620 season 11 00:00:50,620 --> 00:00:54,250 but also by watching the face up the night sky change as well 12 00:00:54,250 --> 00:00:58,690 and will give you a heads up about a planet star rendezvous that happens 13 00:00:58,690 --> 00:01:02,989 only every other year let's show you EC 14 00:01:02,989 --> 00:01:07,340 all has to do with our Earth's yearly journey in its orbit around the Sun 15 00:01:07,340 --> 00:01:11,770 because as our earth orbits the Sun you'll see a slightly different part the 16 00:01:11,770 --> 00:01:12,810 starry sky 17 00:01:12,810 --> 00:01:17,509 each successive evening that is if you go outside every night after sunset for 18 00:01:17,509 --> 00:01:18,979 a year and look up 19 00:01:18,979 --> 00:01:22,940 you'll notice that the various constellations slowly but steadily shift 20 00:01:22,940 --> 00:01:24,940 their positions in the heavens a little bit 21 00:01:24,940 --> 00:01:29,440 West for each night a given star pattern will first appear low in the east 22 00:01:29,440 --> 00:01:33,619 and then gradually become very prominent and high up in early evening 23 00:01:33,619 --> 00:01:36,679 and then we'll continue that slow shift westward 24 00:01:36,679 --> 00:01:39,690 and then completely disappear from the heavens now 25 00:01:39,690 --> 00:01:43,240 when astronomers talk about sky seasons they mean that the particular star 26 00:01:43,240 --> 00:01:43,880 patterns 27 00:01:43,880 --> 00:01:48,420 or constellations %uh that season are those that are high above the horizon in 28 00:01:48,420 --> 00:01:52,450 early evening hours during a given season for instance 29 00:01:52,450 --> 00:01:55,479 and summer time we know that the great summer triangle 30 00:01:55,479 --> 00:01:59,729 and the giant scorpion are always very high and Dominic and early evening 31 00:01:59,729 --> 00:02:00,789 summer skies 32 00:02:00,789 --> 00:02:05,550 and in winter in early evening the giant a Ryan and his dog 33 00:02:05,550 --> 00:02:08,669 always ride high and dominate winters landscape 34 00:02:08,669 --> 00:02:12,050 springtime always has its wonderful Leo the Lion 35 00:02:12,050 --> 00:02:15,050 and the Big Dipper towering over head in early evening 36 00:02:15,050 --> 00:02:18,079 but there's one season when the sky becomes quiet 37 00:02:18,079 --> 00:02:21,209 a season when there are fewer bright stars visible than 38 00:02:21,209 --> 00:02:25,380 any other time of the year and quite appropriately I think that season is 39 00:02:25,380 --> 00:02:25,810 autumn 40 00:02:25,810 --> 00:02:29,430 the season when earth to is quieting down a season 41 00:02:29,430 --> 00:02:33,620 muted Sun and muted starlight a season without social Giants 42 00:02:33,620 --> 00:02:38,750 the season up the soft sky and if you do what I'm about to show you on 43 00:02:38,750 --> 00:02:42,909 at least one evening in autumn every autumn for the rest of your life 44 00:02:42,909 --> 00:02:47,459 your add yet another dimension to your enjoyment and the exquisite fields 45 00:02:47,459 --> 00:02:52,019 that autumn brings simply go outside any autumn evening just 46 00:02:52,019 --> 00:02:56,120 after the Sun has gone down and look for the Giants summer scorpion 47 00:02:56,120 --> 00:02:59,409 with his break reddish orange heart star Antares 48 00:02:59,409 --> 00:03:03,480 as they get ready to set low in the southwest this year 49 00:03:03,480 --> 00:03:06,530 there's an additional point and white just above Antares 50 00:03:06,530 --> 00:03:10,250 it's the reddish orange planet Mars which the Greeks named 51 00:03:10,250 --> 00:03:14,859 Aires their God of War it's commonly stated that the harder the Scorpion and 52 00:03:14,859 --> 00:03:15,469 Tyrese 53 00:03:15,469 --> 00:03:20,099 was named as the rival varies because they appear so much alike in the sky 54 00:03:20,099 --> 00:03:24,499 mars passes close to in Terry's roughly every two years 55 00:03:24,499 --> 00:03:28,530 because in Terry's lies just south on the path to the plants 56 00:03:28,530 --> 00:03:32,590 this coming Monday September 29 be sure to catch mars 57 00:03:32,590 --> 00:03:37,290 in a crescent moon in line with the in Terry's Mars will come back to alignment 58 00:03:37,290 --> 00:03:38,459 with the in Terry's in 59 00:03:38,459 --> 00:03:41,510 August up 20-16 and next time 60 00:03:41,510 --> 00:03:46,909 Saturn will be right there to make it even bet so be sure to get out and watch 61 00:03:46,909 --> 00:03:47,650 in Terry's 62 00:03:47,650 --> 00:03:51,340 mars and the moon next week watchin terry's Inmarsat 63 00:03:51,340 --> 00:03:54,819 as the evening goes along then in the hours before midnight 64 00:03:54,819 --> 00:03:58,810 you'll see for yourself the softer subscribers with a minimum a bright 65 00:03:58,810 --> 00:03:59,430 stars 66 00:03:59,430 --> 00:04:03,790 a time when you'll be able to delight in the exquisite beauty up to seven sisters 67 00:04:03,790 --> 00:04:04,349 rising 68 00:04:04,349 --> 00:04:09,659 then around midnight autumn skies will slowly give way to a preview of winter 69 00:04:09,659 --> 00:04:14,099 as a ride the winter giant boldly rises in the southeast 70 00:04:14,099 --> 00:04:18,488 how fitting how poetic at the sky seasons coincidentally match 71 00:04:18,488 --> 00:04:21,529 are Earth's as regular as clockwork 72 00:04:21,529 --> 00:04:26,010 yes every October of your life summer scorpion will set at sunset 73 00:04:26,010 --> 00:04:29,810 and wenches Orion mall eyes at midnight and hours in between 74 00:04:29,810 --> 00:04:32,980 will be the power to the slideshow impressions cell 75 00:04:32,980 --> 00:04:37,080 get outside under the heavens softly and remember to 76 00:04:37,080 --> 00:04:52,650 keep looking up 77 00:04:52,650 --> 00:04:57,650 well me
