1 00:00:02,436 --> 00:00:04,404 [Preston] What's Up for January? 2 00:00:04,404 --> 00:00:06,607 The planets have some close encounters, 3 00:00:06,874 --> 00:00:08,742 the bright stars of winter 4 00:00:08,742 --> 00:00:11,178 and a chance to catch a comet. 5 00:00:11,778 --> 00:00:14,648 All month after sunset, you can see four planets 6 00:00:14,648 --> 00:00:16,750 without the aid of binoculars or a telescope. 7 00:00:17,217 --> 00:00:20,954 You'll find Mars in the east, Jupiter high overhead 8 00:00:20,954 --> 00:00:23,123 and Saturn in the southwest with Venus. 9 00:00:23,857 --> 00:00:27,160 January 2nd finds the Moon and Mars high in the southeast 10 00:00:27,160 --> 00:00:28,028 after sunset, 11 00:00:28,395 --> 00:00:30,931 in a lovely grouping with the Pleiades and Aldebaran. 12 00:00:31,465 --> 00:00:35,602 Then from about January 18th to the 24th, watch Venus 13 00:00:35,602 --> 00:00:38,939 cross paths with Saturn as the glow of sunset fades. 14 00:00:39,506 --> 00:00:41,508 Look for the pair low in the southwest, 15 00:00:41,508 --> 00:00:44,478 about 45 minutes after the sun dips below the horizon. 16 00:00:45,078 --> 00:00:48,582 The two planets appear their closest on January 22nd, 17 00:00:48,582 --> 00:00:51,618 when they'll be only a third of a degree apart on the sky. 18 00:00:51,985 --> 00:00:53,520 You'll be able to capture both of them 19 00:00:53,520 --> 00:00:54,554 in the same field of view 20 00:00:54,554 --> 00:00:56,556 through binoculars or a small telescope. 21 00:00:56,990 --> 00:01:00,327 On the 23rd, the two planets are still only a degree apart 22 00:01:00,327 --> 00:01:02,963 and will be joined by a slim crescent Moon. 23 00:01:03,597 --> 00:01:06,767 And on January 25th, looking to the southwest 24 00:01:06,767 --> 00:01:10,704 30 to 45 minutes after sunset, look high above Venus and Saturn 25 00:01:10,704 --> 00:01:12,739 to find the Moon only a degree apart 26 00:01:12,739 --> 00:01:15,108 from Jupiter, about halfway up the sky. 27 00:01:16,543 --> 00:01:19,913 January nights are filled with bright stars. 28 00:01:20,414 --> 00:01:22,316 Looking toward the south or southeast 29 00:01:22,316 --> 00:01:25,319 in the first few hours after dark, you'll spy the bright 30 00:01:25,319 --> 00:01:27,888 constellations of winter in the Northern Hemisphere. 31 00:01:28,455 --> 00:01:30,691 Of course, there's Orion the hunter, 32 00:01:30,691 --> 00:01:33,961 the big dog constellation Canis Major, and the lesser 33 00:01:33,961 --> 00:01:37,698 known little dog, Canis Minor, with its bright star Procyon. 34 00:01:38,231 --> 00:01:41,335 And Y-shaped Taurus, the bull, includes 35 00:01:41,335 --> 00:01:44,171 the bright Hyades and Pleiades star clusters. 36 00:01:44,404 --> 00:01:45,639 And just east of Orion, 37 00:01:45,639 --> 00:01:48,008 you'll find the bright stars Castor and Pollux, 38 00:01:48,008 --> 00:01:50,477 which form the heads of the twins in Gemini. 39 00:01:51,078 --> 00:01:53,580 Make sure you take a moment to appreciate the beauty 40 00:01:53,580 --> 00:01:56,049 of the January sky, which more than meets the 41 00:01:56,049 --> 00:01:59,419 definition of “star studded,” with so much to marvel at. 42 00:02:00,754 --> 00:02:02,656 A recently discovered comet 43 00:02:02,656 --> 00:02:05,158 is now passing through the inner solar system 44 00:02:05,158 --> 00:02:07,060 and should be visible with a telescope 45 00:02:07,060 --> 00:02:09,029 and likely with binoculars. 46 00:02:09,029 --> 00:02:14,868 The comet, which has a mouthful of a name C/2022 E3 (ZTF) 47 00:02:14,868 --> 00:02:16,803 was first sighted in March last year 48 00:02:16,803 --> 00:02:18,872 when it was already inside the orbit of Jupiter. 49 00:02:19,606 --> 00:02:22,609 It makes its closest approach to the sun on January 12th 50 00:02:22,609 --> 00:02:25,345 and then passes its closest to Earth on February 2nd. 51 00:02:25,979 --> 00:02:28,915 Comets are notoriously unpredictable, 52 00:02:28,915 --> 00:02:31,518 but if this one continues its current trend in brightness, 53 00:02:31,518 --> 00:02:33,587 it'll be easy to spot with binoculars, 54 00:02:33,854 --> 00:02:36,023 and it's just possible it could become visible 55 00:02:36,023 --> 00:02:38,191 to the unaided eye under dark skies. 56 00:02:38,792 --> 00:02:40,594 Observers in the Northern Hemisphere 57 00:02:40,594 --> 00:02:41,395 will find the comet 58 00:02:41,928 --> 00:02:44,431 in the morning sky as it moves swiftly toward the northwest 59 00:02:44,431 --> 00:02:45,732 during January. 60 00:02:45,732 --> 00:02:46,600 It'll become visible 61 00:02:46,867 --> 00:02:48,702 in the Southern Hemisphere in early February. 62 00:02:49,302 --> 00:02:51,938 This comet isn't expected to be quite the spectacle 63 00:02:51,938 --> 00:02:54,574 that Comet NEOWISE was back in 2020. 64 00:02:54,941 --> 00:02:56,843 But it's still an awesome opportunity 65 00:02:56,843 --> 00:02:58,245 to make a personal connection 66 00:02:58,245 --> 00:03:01,615 with an icy visitor from the distant outer solar system. 67 00:03:03,383 --> 00:03:06,219 Here are the phases of the Moon for January. 68 00:03:07,954 --> 00:03:10,190 Stay up to date with all of NASA's missions 69 00:03:10,190 --> 00:03:13,593 to explore the solar system and beyond at nasa.gov. 70 00:03:14,061 --> 00:03:16,997 I'm Preston Dyches from NASA's Jet Propulsion Laboratory 71 00:03:16,997 --> 00:03:18,465 and that's What's Up for this month.
