The brand new moon happens September 25, at 5:54 p.m. EDT (2154 GMT). The brand new moon occurs a day earlier than Jupiter reaches opposition, when the planet is seen all evening.
The brand new moon happens when the moon is straight between the solar and Earth. The 2 our bodies share the identical celestial longitude, an alignment additionally referred to as a conjunction. Celestial longitude is a projection of the Earth’s personal longitude traces on the sky; throughout new moons, a line drawn from the pole star due south by means of the solar would additionally hit the moon.
When there’s a new moon, the illuminated aspect of the moon faces away from Earth, making it invisible to ground-based observers. The exceptions are when the moon passes straight in entrance of the solar, which creates an eclipse. That will not occur this time – the subsequent one is due on October 25 of this yr.
Moon phases happen at totally different occasions relying on one’s longitude, or time zone. So the brand new moon that happens at 5:54 p.m. in New York occurs on Sept. 26 at 9:54 a.m. Equally, in Mexico Metropolis it’s at 4:54 p.m.

In case you want pictures gear, contemplate our finest cameras for astrophotography and finest lenses for astrophotography to arrange for the subsequent planet sight.
Jupiter at opposition
(opens in new tab)
A day after the brand new moon, on Sept. 26, the planet Jupiter will attain opposition, when it’s on the alternative aspect of the Earth from the Solar (therefore the identify). Oppositions can solely occur for “outer” planets – Mars, Jupiter, Saturn, Uranus, and Neptune. At these occasions the Earth is closest to these planets they usually are usually brighter. They’re additionally seen the complete evening.
On this case the second of opposition is at 3:25 p.m. Jap Time (opens in new tab), in accordance with In-the-Sky.org. From New York Metropolis the planet rises at 6:46 p.m. on the night of Sept. 26 and units the subsequent morning at 6:50 a.m (opens in new tab). The solar units on Sept. 26 on the similar time (opens in new tab), and rises at 6:48 a.m. on the twenty seventh (opens in new tab).
Jupiter can be within the constellation Pisces, the fishes, and so in metropolis areas the planet would be the brightest star-like object within the japanese sky after sundown. How excessive Jupiter will get when it crosses the meridian – the road going by means of the zenith from north to south – will depend on one’s latitude. From New York Metropolis (and different locations within the mid-northern latitudes), Jupiter can be about 49 levels excessive.
From close to the equator, as in Quito, Ecuador, the planet can be virtually straight overhead – at 12:10 a.m. native time on Sept. 27 it will likely be 89 levels excessive (opens in new tab) (and on the northern aspect of the sky, versus the southern). From mid-southern latitudes – locations like Cape City – Jupiter will seem decrease once more, about 56 levels (opens in new tab) above the northern horizon when it crosses the meridian at 12:42 a.m. native time.
Different seen planets
Except for Jupiter, the opposite naked-eye planets can be seen in succession over the course of the evening. On the night of Sept. 25 the primary planet to rise is Saturn, at 5:00 p.m. in New York (opens in new tab), and turns into seen a few half hour to 45 minutes after sundown, relying on how clear the sky is. (A superb train is to see how quickly after sundown one can spot the planet, which can be within the southeastern sky). By the point the solar is 12 levels beneath the horizon at 7:47 p.m. – the tip of nautical twilight – Saturn can be about 24 levels excessive. Saturn is in Capricornus, the Sea Goat, and as Capricornus is a fainter constellation the planet stands out.
Extra southerly areas will see Saturn increased within the sky; in Quito, Saturn rises at 4:17 p.m. native time (opens in new tab) whereas the solar units at 6:08 p.m. (opens in new tab) on Sept. 25; nautical twilight ends at 6:53 p.m. By that point the ringed planet can be about 51 levels above the southeastern horizon. In Cape City, Saturn rises at 3:09 p.m. native time (opens in new tab) and nautical twilight ends at 7:38 p.m. (opens in new tab) At that time Saturn can be 54 levels excessive within the northeast.
Subsequent to rise is Mars, within the constellation Taurus. From New York Metropolis the crimson planet will clear the horizon at 10:20 pm. native time (opens in new tab), and by midnight can be about 17 levels excessive within the east. The planet will seem to the left of Aldebaran, the brightest star in Taurus. Each are a reddish shade, with Mars a extra intense crimson in comparison with Aldebaran’s extra white-orange. Not like Aldebaran, Mars will not twinkle the way in which stars do – as a basic rule, planets shine with a gradual mild.

Mars will seem decrease within the sky as one strikes southwards. In Quito, for instance, Mars rises a bit later, at 11:01 p.m. native time (opens in new tab), and by 11:45 p.m. it will likely be solely 10 levels excessive within the northeast. Additional south (and two time zones eastwards), in Buenos Aires, Mars rises at 12:45 a.m. on Sept. 26 (opens in new tab), and by 1:30 a.m. is simply 7 levels excessive.
Venus is a morning planet; if you’re up early on Sept. 26 the planet rises at 6:11 a.m. native time in New York (opens in new tab). Nonetheless the solar rises solely a few half hour later, and the planet can be misplaced within the glare earlier than it turns into simply seen. Mercury is in the same place (the planet rises at 6:20 on Sept. 26) and is fainter than Venus is. The scenario does not change with one’s location – whereas the rising and setting time will differ, the space from the solar (as measured throughout the celestial sphere) doesn’t.
Constellations: Northern Hemisphere
September and October are when the Northern Hemisphere’s autumn constellations come out and are seen a lot of the evening. Within the early night the summer time stars are setting, and within the wee hours earlier than daybreak one sees the winter stars rising. Between these areas of sky are constellations corresponding to Andromeda, Pegasus, Cetus and Perseus. Generally, the autumn constellations aren’t as brilliant, and far of the sky is taken up with the “west area” — a set of water-themed constellations within the south, notably Capricornus, Aquarius (the Water Provider), Pisces, and Cetus, the Whale or Leviathan.
At about 10 p.m. on the night of Sept. 25, trying in the direction of the south (roughly within the path of Jupiter and above it), one can see the Nice Sq., a gaggle of stars that marks the top of Andromeda and the wings of Pegasus, the legendary flying horse. Alpheratz, the alpha star of Andromeda, can be on the best nook, whereas the opposite three stars are in Pegasus. Andromeda is made up of two curved traces of stars operating roughly eastward. In a darkish sky location one can see the Andromeda Galaxy, as a faint smudge of sunshine; by means of binoculars the spiral form is clearly seen. The Andromeda Galaxy is a few 2.7 million light-years distant.

Wanting straight in the direction of the horizon from the Nice Sq., one sees Jupiter, and if the sky is darkish sufficient, to the best and above the planet is a small circle of stars that marks one of many two fish in Pisces. From the circlet one can comply with a line of faint stars to the east and south (down and to the left) which makes a pointy flip upwards to the opposite circlet of stars, the place the second of the 2 fishes are. That line represents the wire holding the fish collectively. Close to the purpose the place the wire bends occurs to be the place the march equinox is.
To the south of Pisces is Cetus, the Leviathan, the ocean monster that was referred to as as much as eat Andromeda. Cetus can be arduous to see from city areas, however trying beneath Jupiter, one can spot a “V” form of stars that’s the entrance finish of the ocean monster’s head. Typically the constellation is drawn as a sperm whale. Cetus has one notable star, Mira, or Omicron Ceti, which is variable and the very first variable star to be found; it modifications from magnitude 2 to 10 over the course of about 332 days. Its final most — the star was about one one tenth as brilliant as Saturn — was in July, which suggests it’s nonetheless naked-eye seen, although fainter than in the summertime.
Turning northeast, one can see Perseus, the hero who rescued Andromeda from Cetus. Perseus is a brighter group of stars, and makes a compact triangular form. Close to Perseus is Cassiopeia, the Queen and Andromeda’s mom. Cassiopeia can be above Perseus, and is formed like a “W”. You should utilize Cassiopeia to seek out Polaris, much like the Huge Dipper: the open aspect of the “W” faces north, so handing over that path leads proper to Polaris. At about 10 p.m. in mid-northern latitudes the Dipper can be near the horizon, going through upwards.
Rising within the east one will see Auriga, the Charioteer, and simply to the best of it, Taurus the Bull.
Constellations: Southern Hemisphere
Within the Southern Hemisphere, on the latitude of Buenos Aires or Melbourne, on Sept. 25 at about 10 p.m., the Southern Cross is within the south-southwest, low within the sky. The Cross factors to the South Celestial Pole, however there is not a star like Polaris that marks the spot. The pole is about 4 occasions the size of the cross from the Cross itself.
To the best of the Southern Cross and above it’s Rigil Kentaurus, in any other case referred to as Alpha Centauri, well-known for showing in myriad science fiction tales.
Within the southeast and about midway to the zenith (about 42 levels up) is Achernar, the brightest star within the River, which begins within the Southern Hemisphere sky and ends close to the foot of Orion, which begins to rise after midnight. Arising over the southern horizon east of south is Canopus, the brightest star in Carina, the Ship’s Keel, which rises at 8:51 p.m.
Cetus is rising within the northeast at the moment, and within the south-southwest one can see an “the wrong way up” Scorpius going through right down to the horizon. From the place Cetus is trying left (northwards) one encounters Pisces, Pegasus and Cygnus.
New moons and eclipses
New moons aren’t seen until there may be an eclipse; eclipses do not occur each new moon as a result of the orbit of the moon is tilted by about 5 levels relative to the aircraft of the Earth’s orbit, and the node — the purpose the place the orbits intersect — strikes relative to the Earth’s floor. So the moon’s shadow “misses” the Earth more often than not. (The subsequent photo voltaic eclipse is not till Oct. 25, 2022).
