1 00:00:19,919 --> 00:00:25,859 seen shapes in the stars hey there stargazers Ondine regus astronomer for 2 00:00:25,959 --> 00:00:29,796 the Cincinnati observatory and I'm James all Barry director of the kike sola 3 00:00:29,896 --> 00:00:31,998 planetarium in gainesville florida 4 00:00:32,098 --> 00:00:35,368 we're here to help you find your way around the sky 5 00:00:35,468 --> 00:00:39,506 hey Dean have you seen the Big Dipper the summer i have after all it's my 6 00:00:39,606 --> 00:00:43,410 favorite constellation demons 7 00:00:43,510 --> 00:00:47,447 laughing because he knows darn well the Big Dipper is not a constellation 8 00:00:47,547 --> 00:00:51,818 I know I know I just like messing with you James the Big Dipper is only part of 9 00:00:51,918 --> 00:00:55,688 a larger constellation called Ursa Major or the big bear 10 00:00:55,789 --> 00:00:59,826 so if it's not an official constellation what do we call it like to call it an 11 00:00:59,926 --> 00:01:04,497 asterism an asterism is basically just a shape we see in the stars to help us 12 00:01:04,597 --> 00:01:05,999 find our way around 13 00:01:06,099 --> 00:01:10,136 think of it as an unofficial constellation and summertime is a great 14 00:01:10,236 --> 00:01:13,073 time to find many of the asterisms in the sky 15 00:01:13,173 --> 00:01:17,777 exactly who got the summer terrible the fish hook and the teapot 16 00:01:17,877 --> 00:01:22,916 well let's show you ok we have our sky set up for any night this week facing 17 00:01:23,016 --> 00:01:24,751 north west after sunset 18 00:01:24,851 --> 00:01:29,889 now that we're into July the sunsets really late so use this as an excuse to 19 00:01:29,989 --> 00:01:31,791 stay up past your bedtime 20 00:01:31,891 --> 00:01:36,029 definitely because we want you to find your first asterism of the evening up in 21 00:01:36,129 --> 00:01:37,697 the north western sky 22 00:01:37,797 --> 00:01:42,068 there it is standing on its spoon the Big Dipper the formation of those seven 23 00:01:42,168 --> 00:01:44,204 bright stars is unmistakable 24 00:01:44,304 --> 00:01:48,441 4 stars make the spoon of the Big Dipper and three more makeup the handle 25 00:01:48,541 --> 00:01:53,246 now where's that big bear that I'll turn my asterism into a constellation 26 00:01:53,346 --> 00:01:58,551 haha i see it now Ursa Major the Big Bear takes up a lot of space in the sky 27 00:01:58,651 --> 00:02:02,489 the Big Dipper is only the rear end and long tail of the bear while other 28 00:02:02,589 --> 00:02:05,158 fainter stars Mark his head and feet 29 00:02:05,258 --> 00:02:09,629 astronomers don't just stop there to them everything within this boundary 30 00:02:09,729 --> 00:02:14,667 every star every deep space object is part of the constellation Ursa Major 31 00:02:14,767 --> 00:02:17,270 wow that's a big bear 32 00:02:17,370 --> 00:02:22,642 now we're facing east and here you can find another huge ass tourism in the sky 33 00:02:22,742 --> 00:02:26,412 I'll give you two hints it's up all summer and it's in the shape of a 34 00:02:26,513 --> 00:02:28,014 triangle 35 00:02:28,114 --> 00:02:31,551 yep we call it the summer triangle who said astronomy was tough to follow 36 00:02:31,651 --> 00:02:37,023 brightest and blues to the 3 stars in the summer triangle is Vega down into 37 00:02:37,123 --> 00:02:41,794 the left is Delta and way over to the right is all tear each of these stars 38 00:02:41,895 --> 00:02:46,099 belongs to its own constellation vega is part of liar of the harp 39 00:02:46,199 --> 00:02:51,604 who stars make a little parallelogram Deneb is the tale of Cygnus the Swan who 40 00:02:51,704 --> 00:02:56,809 I can actually picture a swan and those stars and all tear is the eagle eye of 41 00:02:56,910 --> 00:02:59,012 the constellation aquila the eagle 42 00:02:59,112 --> 00:03:03,550 so this asterism the summer triangle really incorporates three regions of 43 00:03:03,650 --> 00:03:05,885 three different constellations 44 00:03:05,985 --> 00:03:11,124 now let's face south and look low on the horizon for two more distinct asterisms 45 00:03:11,224 --> 00:03:16,563 here we find the stars I most associate with summer looking like the letter j or 46 00:03:16,663 --> 00:03:20,466 a big fish look ad in The Fader stars around the fish hook and you'll see the 47 00:03:20,567 --> 00:03:24,771 constellation scorpius the Scorpion at the heart of the Scorpion you find a red 48 00:03:24,871 --> 00:03:29,909 supergiant star called and Terry's as an added special effect and terry's is 49 00:03:30,009 --> 00:03:33,680 often low in the southern sky and appears to flicker like a beating heart 50 00:03:33,780 --> 00:03:38,284 through the thicker atmosphere the planets Mars and Saturn are also hang 51 00:03:38,384 --> 00:03:43,156 around scorpius's summer now to the left of the fishhook you can find stars in 52 00:03:43,256 --> 00:03:47,293 the shape of a teapot these stars are part of a larger constellation called 53 00:03:47,393 --> 00:03:49,295 Sagittarius the Archer 54 00:03:49,395 --> 00:03:54,667 he's a centaur half man half horse with his legs down below the horizon for most 55 00:03:54,767 --> 00:03:56,302 people in the US 56 00:03:56,402 --> 00:04:00,406 other than the teapot the remaining stars in sagittarius are tough to find 57 00:04:00,506 --> 00:04:05,311 but the asterism marks the center's body and out stretch bow and arrow 58 00:04:05,411 --> 00:04:09,682 what's the aiming at and Tory's the heart of the Scorpion of course 59 00:04:09,782 --> 00:04:14,754 watch out Scorpius so find your favorite asterism tonight from the Big Dipper in 60 00:04:14,854 --> 00:04:18,491 the northwest to the summer triangle high in the east to the fish hook in the 61 00:04:18,591 --> 00:04:22,591 South next to the teapot and it's all there when you keep looking up
