WEBVTT 00:01.590 --> 00:20.820 web 00:20.820 --> 00:25.320 flying along the Milky Way Heather stargazers 00:25.320 --> 00:29.369 I'm james oberg director the key cassava plant planetarium in Gainesville Florida 00:29.369 --> 00:32.738 I'm di Maria's astronomer for the Cincinnati Observatory 00:32.738 --> 00:36.210 this week will be your guide to the galaxy yep 00:36.210 --> 00:39.610 we're going to show you the Milky Way something I hardly 00:39.610 --> 00:43.120 ever get to see in Florida how many times have you seen the Milky waiting 00:43.120 --> 00:46.610 haha the call the Milky Way I see in Cincinnati is a 00:46.610 --> 00:51.309 filled with chocolate and new get for me light pollution is a big problem 00:51.309 --> 00:56.230 citylights aluminate signs parking lots buildings and also the night sky 00:56.230 --> 00:59.720 the more like that we shine up the less like the stars 00:59.720 --> 01:03.909 shine down even though it's invisible from cities James and I can share as 01:03.909 --> 01:06.659 sneaky tip to find the Milky Way in your Sky 01:06.659 --> 01:11.380 let's show you okay let's pretend it's 10 o'clock at night 01:11.380 --> 01:15.030 and we're far from city lights may hand it's dark out here 01:15.030 --> 01:19.570 now and look at all the summer stars you can see so many stars that you can't 01:19.570 --> 01:20.680 even count them all 01:20.680 --> 01:25.039 you can also see a band a faint light stretching from the northeast 01:25.039 --> 01:28.479 up overhead and down to the southwest this 01:28.479 --> 01:31.840 is the Milky Way when you look at the Milky Way you're observing 01:31.840 --> 01:37.070 billions and billions of stars most the stars in our galaxy are stretched out in 01:37.070 --> 01:37.630 a band 01:37.630 --> 01:41.770 all around us with us in the middle there are so many stars a our line of 01:41.770 --> 01:44.439 sight that they appear as milky clouds 01:44.439 --> 01:48.399 most ancient cultures were just as fascinated with the Milky Way 01:48.399 --> 01:52.640 as they were with any planet or constellation you can definitely see why 01:52.640 --> 01:58.240 out in the country it dominates the sky some bright and famous constellations 01:58.240 --> 02:00.649 can be found along this galactic River 02:00.649 --> 02:04.159 such as Casio Pierre the Queen Cygnus the Swan 02:04.159 --> 02:08.538 and Scorpius the Scorpion Cassie appear as one of the most recognizable 02:08.538 --> 02:09.500 constellations 02:09.500 --> 02:12.640 in the summer evenings she sits on her throne 02:12.640 --> 02:17.130 in the north eastern sky what you mean those stars that look like the letter W 02:17.130 --> 02:18.620 that's a queen 02:18.620 --> 02:22.900 use your imagination Dean well that picture certainly helps but 02:22.900 --> 02:26.240 I guess some imagination challenged in that case 02:26.240 --> 02:30.970 picture this W shape stars as Cassie apiece crowned sparkling with five 02:30.970 --> 02:31.900 stellar joel's 02:31.900 --> 02:35.470 okay now that I can see now 02:35.470 --> 02:40.110 kickback and look high in the sky almost straight overhead you'll see three very 02:40.110 --> 02:42.470 bright stars marking the summer triangle 02:42.470 --> 02:45.730 the summer triangle is not an official constellation 02:45.730 --> 02:49.100 it's really three constellations Lyra the harp 02:49.100 --> 02:54.180 Cygnus the Swan and a quality Eagle let's focus on Cygnus since it's 02:54.180 --> 02:56.190 probably the easiest to identify 02:56.190 --> 03:01.010 because its cross like shape in fact it's also called the northern cross 03:01.010 --> 03:05.470 sicknesses brightest star is Dana which marks the tale The Swan 03:05.470 --> 03:09.700 sickness is located in an extremely rich part in the Milky Way 03:09.700 --> 03:13.400 so imagine it flying along the Great river in the sky 03:13.400 --> 03:16.810 near dead the Milky Way branches into two channels 03:16.810 --> 03:20.720 leaving a dark region in the middle this is called the sickness rift 03:20.720 --> 03:24.670 or the northern call sec now face South 03:24.670 --> 03:28.460 here the Milky Way threads between two xoxo constellations 03:28.460 --> 03:32.240 Scorpius and secretary s Scorpius the scorpion is 03:32.240 --> 03:36.220 easy to spot with its bright red star for heart and its curtail 03:36.220 --> 03:40.660 and stinger stars the stars and said the terrace resemble more about teapot been 03:40.660 --> 03:42.530 a centaur wielding a bow and arrow 03:42.530 --> 03:47.170 when you look between Scorpius and said it areas you're peering into the center 03:47.170 --> 03:48.079 of our galaxy 03:48.079 --> 03:52.350 in that direction are billions and billions of stars 03:52.350 --> 03:56.010 and at the very center those is a supermassive black hole 03:56.010 --> 04:01.060 X-ray satellites have captured amazing activity around this region called Sajan 04:01.060 --> 04:02.040 teri is a 04:02.040 --> 04:05.180 of course you can see the Milky Way 04:05.180 --> 04:09.360 if you're a citibank and stargazer let's show you the difference between a rural 04:09.360 --> 04:10.050 sky 04:10.050 --> 04:13.180 and a light polluted skies yaks 04:13.180 --> 04:16.720 what a difference even though the Milky Way's disappeared 04:16.720 --> 04:20.320 we still have three constellations clearly visible to guide us 04:20.320 --> 04:23.400 Casio p in the Northeast Cygnus high overhead 04:23.400 --> 04:26.740 and Scorpius low in the south and that's where the Milky Way 04:26.740 --> 04:31.180 is even if you can't see it once you identify Casio p.m. 04:31.180 --> 04:36.190 Cygnus or scorpions scan these regions on the sky with the not 04:36.190 --> 04:40.630 just a little magnification well stars will be revealed 04:40.630 --> 04:44.850 so start counting those billions and billions of stars tonight 04:44.850 --> 04:52.820 as you keep looking up 04:52.820 --> 04:57.820
