1 00:00:20,220 --> 00:00:25,925 great midnight triangle fest welcome stargazers I'm Dean Regas a stronger 2 00:00:26,026 --> 00:00:30,530 from the Cincinnati Observatory and I'm James Albert director the kike Sola plop 3 00:00:30,630 --> 00:00:34,567 planetarium in Gainesville Florida summer is almost here and our favorite 4 00:00:34,667 --> 00:00:39,272 winter constellations are almost gone but don't despair after midnight 5 00:00:39,372 --> 00:00:42,876 any night this week we have 250 triangles that are going to dazzle the 6 00:00:42,976 --> 00:00:47,547 night sky that's right James one of the Triangle's you see every summer but the 7 00:00:47,647 --> 00:00:52,352 other one is formed by a unique arrangement of the planet's plus if you 8 00:00:52,452 --> 00:00:56,656 go outside at midnight the morning of May 15th and 16th you'll see yet another 9 00:00:56,756 --> 00:01:01,728 triangle formed by the moon a planet and a star wondering what we're talking 10 00:01:01,828 --> 00:01:06,933 about let's show you ok we have our skies set for midnight the morning of 11 00:01:07,033 --> 00:01:11,337 May 15th if you look to the west will see the giant planet jupiter among the 12 00:01:11,438 --> 00:01:16,042 stars of Leo the Lion Jupiter will have a close conjunction with the moon on may 13 00:01:16,142 --> 00:01:21,314 fifteenth and sixteenth so if you're into geometric shapes like we are you 14 00:01:21,414 --> 00:01:25,652 can form a triangle between Jupiter the waxing crescent moon and the star 15 00:01:25,752 --> 00:01:30,990 Regulus on may fifteenth and then use leos tale start the nebula the Mormon 16 00:01:31,091 --> 00:01:36,529 triangle at Jupiter and the moon on May 16 since the moon moves pretty quickly 17 00:01:36,629 --> 00:01:41,134 triangles formed using the moon only last a few hours so if you want to see 18 00:01:41,234 --> 00:01:43,470 more stable triangles all week long 19 00:01:43,570 --> 00:01:47,440 check out the sky toward the southeast and you can do that any night this week 20 00:01:47,540 --> 00:01:49,075 or next 21 00:01:49,175 --> 00:01:53,913 at midnight any night this week look southeast you'll spot our next triangle 22 00:01:54,013 --> 00:01:58,918 the northernmost point in this triangle is the red planet Mars and it's right 23 00:01:59,018 --> 00:02:03,690 next to the star shubha the center star of the three stars making the face of 24 00:02:03,790 --> 00:02:08,528 Scorpius the Scorpion Mars is fairly close to us right now and was named 25 00:02:08,628 --> 00:02:13,399 after the Roman god of war because red color of this planet reminded many 26 00:02:13,500 --> 00:02:18,671 ancient people of blood and violence the second part of our triangle is formed by 27 00:02:18,771 --> 00:02:24,110 the ringed planet Saturn Saturn is an excellent spot for viewing right now and 28 00:02:24,210 --> 00:02:27,947 its rings are tipped toward us in such a way that if you have a small telescope 29 00:02:28,047 --> 00:02:32,719 will get a picture perfect view of Saturn Saturn reaches opposition in just 30 00:02:32,819 --> 00:02:36,689 a few weeks so it'll get bigger and brighter as the days pass so definitely 31 00:02:36,789 --> 00:02:41,761 get outside and final part of our triangle is formed by the star in 32 00:02:41,861 --> 00:02:47,567 taryn's Antares means rival Mars and if you look at it closely as the same 33 00:02:47,667 --> 00:02:52,539 reddish tint is mars however this red celestial Dazzler isn't ready for the 34 00:02:52,639 --> 00:02:57,777 same reason that Mars is red and Terry's is a red supergiant star that's nearing 35 00:02:57,877 --> 00:02:59,445 the end of its life 36 00:02:59,546 --> 00:03:04,517 the star is just over five hundred and fifty light years away from us so large 37 00:03:04,617 --> 00:03:09,689 that you could easily fit the orbits of Mercury Venus Earth and Mars inside 38 00:03:09,789 --> 00:03:14,994 already let's take a look at our second triangle of the midnight triangle fast 39 00:03:15,094 --> 00:03:20,433 ok we still have our sky set to midnight and if you look east you'll see the 40 00:03:20,533 --> 00:03:26,306 three billion stars summer triangle then gets the brightest damages the brain 41 00:03:26,406 --> 00:03:30,977 storm signals that alter his brightest star of Aquila the eagle 42 00:03:31,077 --> 00:03:37,217 the brightest star of the 38 Vega only 25 light years from Earth and is one of 43 00:03:37,317 --> 00:03:41,020 the most luminous stars in our neighborhood the second brightest star 44 00:03:41,120 --> 00:03:45,225 in the summer triangle is an alternate only seventeen light years from Earth of 45 00:03:45,325 --> 00:03:50,396 all the stars nearest alter spins the fastest and its equator alter can make 46 00:03:50,496 --> 00:03:53,333 one complete rotation only nine hours 47 00:03:53,433 --> 00:03:57,470 compare that to our side which takes twenty six days to complete one rotation 48 00:03:57,570 --> 00:04:02,909 last start of the summer triangle is the blue-white supergiant Danny Danon just 49 00:04:03,009 --> 00:04:08,648 happens to be the North Star on mars and is almost 60,000 times as bright as our 50 00:04:08,748 --> 00:04:13,386 son however because it's over three thousand light years away from us 51 00:04:13,486 --> 00:04:19,158 it appears much fainter than Vega and Altair so there you have it too right 52 00:04:19,259 --> 00:04:25,064 triangles to light up your night sky Mars Saturn and I'm tired eyes and the 53 00:04:25,164 --> 00:04:30,837 ever-popular and lovely summer triangle Vega solitaire and Jenna and if you're 54 00:04:30,937 --> 00:04:32,472 outside later this week 55 00:04:32,572 --> 00:04:36,843 Jupiter and the moon make a triangle with Regulus on May 15 and Annapolis on 56 00:04:36,943 --> 00:04:40,943 May 16 keep let me know
