1 00:00:05,150 --> 00:00:01,969 [Music] 2 00:00:07,610 --> 00:00:05,160 what's up for February the brightest 3 00:00:10,669 --> 00:00:07,620 planets converge the constellation 4 00:00:12,830 --> 00:00:10,679 auriga and two star clusters you might 5 00:00:14,930 --> 00:00:12,840 want to get serious about 6 00:00:17,269 --> 00:00:14,940 all month long you'll notice the two 7 00:00:19,189 --> 00:00:17,279 brightest planets in the sky Jupiter and 8 00:00:21,470 --> 00:00:19,199 Venus appear closer together each 9 00:00:24,170 --> 00:00:21,480 evening find them in the West in the 10 00:00:26,509 --> 00:00:24,180 hour or so after Sundown on February 11 00:00:28,670 --> 00:00:26,519 22nd the Crescent Moon sits just a 12 00:00:30,710 --> 00:00:28,680 degree apart from Jupiter with Venus 13 00:00:32,510 --> 00:00:30,720 hanging beneath them the two planets 14 00:00:35,030 --> 00:00:32,520 then continue to get closer in the sky 15 00:00:37,490 --> 00:00:35,040 over the following week culminating in a 16 00:00:39,470 --> 00:00:37,500 close conjunction on March 1st 17 00:00:42,110 --> 00:00:39,480 another nice pairing takes place on 18 00:00:43,910 --> 00:00:42,120 February 27th when the moon and Mars 19 00:00:46,069 --> 00:00:43,920 will appear less than a degree apart 20 00:00:48,650 --> 00:00:46,079 you'll find them high in the southwest 21 00:00:51,350 --> 00:00:48,660 after sunset 22 00:00:52,850 --> 00:00:51,360 the constellation origa makes for a 23 00:00:54,310 --> 00:00:52,860 worthy Target to pick out of the 24 00:00:57,229 --> 00:00:54,320 February Sky 25 00:00:59,389 --> 00:00:57,239 origa represents an ancient Chariot 26 00:01:01,850 --> 00:00:59,399 driver and it's often depicted as the 27 00:01:03,529 --> 00:01:01,860 entire person but given the outline you 28 00:01:05,210 --> 00:01:03,539 might prefer to think of it as one of a 29 00:01:08,149 --> 00:01:05,220 chariot's Wheels 30 00:01:11,450 --> 00:01:08,159 the brightest star in auriga is Capella 31 00:01:13,789 --> 00:01:11,460 now in Latin capella is a word for a 32 00:01:15,289 --> 00:01:13,799 female goat and in addition to Capella 33 00:01:18,830 --> 00:01:15,299 there are these three little stars 34 00:01:21,410 --> 00:01:18,840 nearby known as the kids as in the name 35 00:01:23,929 --> 00:01:21,420 for baby goats which is pretty fun 36 00:01:26,630 --> 00:01:23,939 opposite capella toward the south is the 37 00:01:28,789 --> 00:01:26,640 bright star elnath technically it's part 38 00:01:31,570 --> 00:01:28,799 of Taurus next door but it helps to find 39 00:01:33,890 --> 00:01:31,580 the roughly circular shape of Oregan 40 00:01:35,749 --> 00:01:33,900 appears high in the Western sky on 41 00:01:37,609 --> 00:01:35,759 February evenings and it's relatively 42 00:01:38,630 --> 00:01:37,619 easy to find thanks to Capella and 43 00:01:41,330 --> 00:01:38,640 elnath 44 00:01:43,910 --> 00:01:41,340 from Orion look northward twice the 45 00:01:46,130 --> 00:01:43,920 height of Orion to find capella then 46 00:01:47,749 --> 00:01:46,140 spot elnath on a ridah's opposite side 47 00:01:49,609 --> 00:01:47,759 and from there it's pretty easy to 48 00:01:51,410 --> 00:01:49,619 identify the other stars that round out 49 00:01:53,050 --> 00:01:51,420 the shape of the charioteer 50 00:01:56,149 --> 00:01:53,060 constellation 51 00:01:58,010 --> 00:01:56,159 all month long observers with access to 52 00:02:00,590 --> 00:01:58,020 a good pair of binoculars or a small 53 00:02:02,810 --> 00:02:00,600 telescope can hunt for two easy star 54 00:02:04,310 --> 00:02:02,820 clusters using the brightest star in the 55 00:02:08,389 --> 00:02:04,320 sky as a guidepost 56 00:02:10,669 --> 00:02:08,399 their two open star clusters m41 and m47 57 00:02:12,470 --> 00:02:10,679 they're called open because their stars 58 00:02:14,990 --> 00:02:12,480 are close together in space but in sort 59 00:02:17,330 --> 00:02:15,000 of a diffuse structure to find them 60 00:02:18,890 --> 00:02:17,340 start with brilliant Sirius which is 61 00:02:22,430 --> 00:02:18,900 easy to pick out toward the South and 62 00:02:24,530 --> 00:02:22,440 the winter night sky m41 lies just four 63 00:02:26,089 --> 00:02:24,540 degrees south of Sirius and should be 64 00:02:28,190 --> 00:02:26,099 visible in the same field of view and 65 00:02:30,650 --> 00:02:28,200 binoculars where it appears as sort of a 66 00:02:32,990 --> 00:02:30,660 faint patch of light it's about as wide 67 00:02:35,690 --> 00:02:33,000 on the sky as the full moon though in 68 00:02:38,449 --> 00:02:35,700 actual extent it's about 25 light years 69 00:02:41,690 --> 00:02:38,459 across and is located about 2 300 light 70 00:02:43,670 --> 00:02:41,700 years away from us to find m47 you can 71 00:02:45,410 --> 00:02:43,680 also start at Sirius and work your way 72 00:02:47,210 --> 00:02:45,420 over toward the East about 12 degrees 73 00:02:49,369 --> 00:02:47,220 and then a couple of degrees to the 74 00:02:51,910 --> 00:02:49,379 north it's about the same size on the 75 00:02:55,670 --> 00:02:51,920 sky as m41 but just a little brighter 76 00:02:57,410 --> 00:02:55,680 m47 lies about 1600 light years away and 77 00:02:58,910 --> 00:02:57,420 occupies a volume of space about 12 78 00:03:01,729 --> 00:02:58,920 light years across 79 00:03:03,710 --> 00:03:01,739 our own son is thought to have formed as 80 00:03:06,110 --> 00:03:03,720 part of a cluster like these 81 00:03:07,729 --> 00:03:06,120 so finding them in the February sky can 82 00:03:09,150 --> 00:03:07,739 be a pretty neat way to connect with our 83 00:03:11,270 --> 00:03:09,160 own Cosmic Origins 84 00:03:12,890 --> 00:03:11,280 [Music] 85 00:03:16,130 -->
