The brand new moon of January will be at 2:52 p.m. EST (1952 GMT) on Jan. 18, in accordance with the U.S. Naval Observatory.
A new moon is, technically, a conjunction of the solar and moon. The 2 bodies half the the same celestial longitude — if one drew a north-south line from the North Celestial Pole (true reach where the Pole Smartly-known person, Polaris, is found) the solar and moon would both be on it.
Novel moon skies are darkish, especially when in contrast to nights when the moon is out; even a half of-moon (when the moon is initially or final quarter fragment) is the 2nd brightest object in the sky after the solar. Which implies the nights on either facet of a new moon are factual for searching at fainter stars and seeing the bare-see nebulas and star clusters, significantly if one can glance the sky from a build a ways from city lights.
Viewed planets
On the night of Jan. 18, there will be two planets considered: Saturn and Jupiter. By about 6 p.m., Saturn will be about 37 levels above the southwestern horizon. In Novel York City, the solar devices at 4:56 p.m.; the timing and Saturn’s build in the sky would possibly well be the same for wherever reach 40 levels north, corresponding to Chicago, Denver, Detroit, or Sacramento. In Novel York, Saturn devices at 9:Forty eight p.m.
Jupiter, meanwhile, rises at 3:58 p.m.; for the reason that sky darkens fully by about 6 p.m., one will test up on Jupiter about 21 levels high in the east. Jupiter is brighter than the surrounding stars; one manner to title Jupiter is glance for a rough triangle of “stars” with two of them to the left (north) of a brighter one; the brighter, steadier light is Jupiter. Jupiter is considered nearly all night; the planet does no longer quandary till 6:49 a.m. (January 19) in Novel York, and it reaches its absolute top altitude (known as transit) at 11:23 p.m. Jan. 18.
Unfortunately for planet hunters, Mercury, Venus and Mars are all too shut to the solar to survey; they are going to reach out of the solar glare in the weeks following the brand new moon. Mercury will emerge as an “evening star” in February and Venus will carry out so in March. Mars will emerge into the predawn skies in March.

For Southern Hemisphere skywatchers, the sky would now not get darkish till 9:30 p.m.; because it is the austral summer season, the solar devices late. In Santiago, Chile, as an illustration, sunset is now not till 8:54 p.m. local time on Jan. 18. Santiago is about as a ways south of the equator — 33 levels — as Dallas or Charleston, South Carolina is north of it, and is of a the same latitude to cities corresponding to Cape Town and Melbourne, Australia.
From Santiago, Saturn will be 22 levels high in the west by 10 p.m. The ringed planet devices at 11:54 p.m. Jan. 18. Jupiter, meanwhile, rises at 8:11 p.m. local time, and by 10 p.m. is in the northeastern sky about 18 levels high.
Stars and constellations
Winter constellations are in fleshy swing for Northern Hemisphere observers in the latter half of of January. Two hours after sunset — at about 7 p.m. in Novel York— some of the brightest constellations get risen — Orion (the Hunter), Gemini (the Twins), Taurus (the Bull), Canis Minor (the Minute Dogs) and Auriga (the Charioteer). Perceive low in the southeast to space the brightest star in the sky, Sirius, the alpha star of Canis Major, the Tall Dogs.
It’s possible you’ll perchance perchance perchance perchance originate up by figuring out Gemini, as right here’s the constellation Jupiter is in. The 2 stars to the left (north) of Jupiter are Castor and Pollux, with Pollux being the one closer to the horizon. nearly stage with Jupiter. If you glance down and to the true about four cases Jupiter’s distance from Pollux, you will test up on a incandescent white star; right here’s Procyon, the brightest star in Canis Minor. Wander additional to the true (south) and you test up on Sirius, which is recognizable by its blue-white hue and its brightness.
In an instant above Sirius, about a third of the manner from the horizon to the zenith (the level straight overhead) is Orion. Orion will be identified by the three stars that fabricate up his belt — early in the night, they are going to appear to fabricate an nearly vertical line. Going up from the horizon, the first star is Alnitak, the 2nd is Alnilam, and the third is Mintaka. Perceive somewhat up and to the left of the belt and one can space a incandescent reddish-orange star. Here’s Betelgeuse (pronounced indulge in beetle-juice), marking one of Orion’s shoulders. Above and to the true of Betelgeuse is Bellatrix, his a number of shoulder. On the true facet of Orion’s Belt, about the the same distance from Mintaka as Betelgeuse is from Alnitak, is a incandescent blue-white star; right here’s Rigel.

Since the night will be moonless, true to the true of Orion’s Belt and below it, you would possibly well perchance perchance perchance perchance perchance, from a wretched-sky build a ways from city lights, mark a neighborhood of faint stars that’s Orion’s sword, and in that neighborhood, it is potential for you to to space the Orion Nebula.
