The last or third quarter moon rises around 2 a.m. and sets around 1 p.m. It is most easily seen just after sunrise in the southern sky.


Thu., May 9, 8:28 p.m. EDT

New Moon

The moon is not visible on the date of new moon because it is too close to the sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise. It is visible low in the west an evening or two after new moon.

Sat., May 18, 12:34 a.m. EDT

First Quarter Moon

The first quarter moon rises around 1 p.m. and sets around 2 a.m. It dominates the evening sky.

Sat., May 25, 12:25 a.m. EDT

Full Moon

The full moon of May is called the Milk Moon. Its Cree name is Aligipizun, meaning “Frog Moon.” Other names are Corn Planting Moon, Corn Moon, Hare Moon, and Flower Moon. In Hindi it is known as Buddha Poornima. Its Sinhala (Buddhist) name is Vesak. The full moon rises around sunset and sets around sunrise, the only night in the month when the moon is in the sky all night long. The rest of the month, the moon spends at least some time in the daytime sky.

Thu., May 31, 2:58 p.m. EDT

Last Quarter Moon

This is the second last quarter moon this month. It rises around 1 a.m. and sets around 1 p.m. It is most easily seen just after sunrise in the southern sky.


Observing Highlights

Fri., May 10

Annular Solar Eclipse

An annular solar eclipse will be visible in a narrow path stretching from central Australia across the south Pacific Ocean. Partial phases of this eclipse will be visible over a much larger area. This is how it will look at maximum eclipse in Cooktown, Australia.

Sat., May 11, after sunset

The moon framed by Jupiter and Venus

Venus has now moved into the evening sky, and tonight it and Jupiter frame the slender crescent moon.

Wed., May 22, before sunrise

Spica near the moon

The moon will move closer to the bright star Spica all night long, getting closest just around the time the moon sets. As seen from southeast Asia, the Philippines, Indonesia, northeastern Australia, and Polynesia, the moon will actually pass in front of Spica.

Thu., May 23, before sunrise

Saturn near the moon

The following night, the moon will move closer to Saturn, again getting closer all night.

Fri., May 24, after sunset

Venus and Mercury in conjunction

Venus and Mercury are in close conjunction, with Jupiter a few degrees away.

Sun., May 26, after sunset

Planetary triangle

Three bright planets, Mercury, Venus, and Jupiter, form a 2-degree equilateral triangle in the western sky just after sunset.

Tue., May 28, after sunset

Venus and Jupiter in conjunction

The three planets rearrange themselves so that Jupiter and Venus are only a degree apart, with Mercury just above.


Planets


Mercury will be in the western  sky at sunset for the last week of May, moving towards maximum elongation on June 12. Although only an average apparition of Mercury, its proximity to the brighter planets Venus and Jupiter will make Mercury easier than usual to spot. In particular it will be in close conjunction with Venus on May 24.

Venus is now an “evening star” setting just after the sun.

Mars is on the far side of the sun, not visible this month.

Jupiter continues its stay in Taurus. It is low in the western sky at dusk, and sets soon afterwards.

Saturn is just past opposition near the border between Libra and Virgo. It is visible most of the night.

Uranus is in Pisces, rising just before the sun.

Neptune is in Aquarius all month, visible in the morning sky.

Wed., April 10, 5:35 a.m. EDT

New Moon

The moon is not visible on the date of new moon because it is too close to the sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise. It is visible low in the west an evening or two after new moon.

Thu., April 18, 8:31 a.m. EDT

First Quarter Moon

The first quarter moon rises around 12:30 p.m. and sets around 3 a.m. It dominates the evening sky.

Thu., April 25, 3:57 p.m. EDT

Full Moon

The full moon of April is called the Seed Moon. Its Cree name is Kiskipizun, meaning “Gray Goose Moon.” Other names are Sprouting Grass Moon, Fish Moon, Growing Moon, Waking Moon, and Pink Moon. In Hindi it is known as Hanuman Jayanti. Its Sinhala (Buddhist) name is Bak. The full moon rises around sunset and sets around sunrise, the only night in the month when the moon is in the sky all night long. The rest of the month, the moon spends at least some time in the daytime sky.

 

Observing Highlights

Sun., April 14, 2 p.m. EDT

Jupiter north of the moon

Jupiter will be 2 degrees north of the moon, giving an excellent opportunity to view the giant planet is the daylight sky. Quite a few people have seen Venus with their unaided eyes in daylight, but very few have seen Jupiter. Locate it first with binoculars, then try to spot it with the naked eye.

Wed., April 24, 8 p.m. local time

Spica near the moon

Look closely at the rising moon tonight. Notice a tiny star just above it? That’s Spica, the brightest star in the constellation Virgo. As seen from Central America, the Caribbean, and southern Africa, the moon will actually pass in front of Spica.

Thu., April 25

Partial Lunar Eclipse

The moon will pass through the outer parts of the moon’s shadow tonight for observers over much of the Eastern Hemisphere. Unfortunately this eclipse will not be visible anywhere in North America.

Sun., April 28, 4 a.m. EDT

Saturn at opposition

Saturn is directly opposite the sun in the sky. It sits on the boundary between the constellations Virgo and Libra, just to the east of the bright star Spica. It is visible all night, rising in the east as the sun sets in the west, and setting in the west as the sun rises in the east.


Planets


Mercury will be in the eastern  sky at sunrise all month, but will be very low for observers in the Northern Hemisphere. Southerners will fare better: this will be their best morning apparition of the year.

Venus is on the far side of the sun, and too close to it to be observed all month.

Mars is on the far side of the sun, being in conjunction with it on April 18.

Jupiter continues its stay in Taurus. It is high in the western sky in the early evening and sets in the northwest around midnight.

Saturn is in opposition in Libra on April 28. It is visible all night.

Uranus is in Pisces but still too close to the sun to be observed.

Neptune is in Aquarius all month, now visible in the morning sky.

Another close conjunction between Jupiter and the Moon, close to Aldebaran and the Hyades. Say farewell to the Pleiades and the Orion Nebula, now sinking fast in the west.

Wed., March 20, 7:02 a.m. EDT

Vernal equinox

The Sun crosses the celestial equator heading north, marking the beginning of Spring in the Northern Hemisphere. Notice the close gathering of the planets Uranus, Mars and Venus close to the Sun: all are on the far side of the Sun relative to Earth..

Wed., March 27, early evening

Spica and the Moon

For the second time this month, the moon passes close to Spica. This time the moon will occult Spica for observers in southeast Asia, northern Australia, and the many islands to the west, north and east.

Sun., March 31, morning twilight

Mercury at greatest elongation west

This is not a good opportunity for observers in the Northern Hemisphere to observe Mercury in the morning sky, as shown here; Mercury will be much higher for observers in the Southern Hemisphere. Sweep the eastern horizon with binoculars to pick up Mercury’s tiny speck of light.


Planets


Mercury will be in the eastern  sky towards the end of the month, the best opportunity for observers in the Southern Hemisphere to see it as an “morning star” in 2013.

Venus is now very low in the southeast at sunrise, and will be superior conjunction with the sun on March 28, moving into the evening sky.

Mars has faded into the west moving behind the sun. It spends most of the month in the constellation Pisces.

Jupiter continues its stay in Taurus close to Aldebaran and the Hyades. It is high in the southwestern sky in the early evening and sets in the northwest around 1 a.m.

Saturn is spends the month in western Libra. It rises in the east at around 11:30 p.m., and is visible the rest of the night.

Uranus is in Pisces but too close to the sun to be observed.

Neptune is in Aquarius all month, too close to the sun to be observed.

Spica north of the moon

The moon will be close to the bright star Spica. Observers in southern Africa and eastern Australia will see the moon occult Spica.

Fri., February 8, 4 p.m. EST

Mercury north of Mars

The two planets Mercury and Mars will be in a close conjunction. Since both are close to the sun, this will be difficult to observe, as there is only a narrow window between when the sky gets dark enough after sunset and when the two planets are high enough above the horizon to still be visible. Binoculars or a telescope recommended

Sat., February 16, evening twilight

Mercury at greatest elongation east

This is the best opportunity this year for observers in the Northern Hemisphere to observe Mercury in the evening sky. Sweep the western horizon with binoculars to pick up Mercury’s tiny speck of light.

Mon., February 18, early evening

Jupiter and the Moon

Another close conjunction between Jupiter and the Moon, flanked by Aldebaran and the Hyades to the left and the Pleiades to the right. The Moon will actually pass in front of Jupiter for viewers in the southern Indian Ocean. Southern Australia and Tasmania. Shown here is the view from Melbourne, Australia.

Mon., February 18, early evening

Vesta and the Moon

The moon will pass just south of the bright asteroid Vesta, making it easier to locate than usual. The moon will occult Vesta as seen from central South America and much of western and southern Africa.


Planets


Mercury will be well placed in the western  sky for most of the month, the best opportunity to see it as an “evening star” in 2013.

Venus is now very low in the southeast at sunrise, heading towards superior conjunction with the sun on March 28.

Mars has faded into the west moving behind the sun. It rapidly crosses the entire constellation of Aquarius this month. Mars passes just south of Neptune on February 4, but Neptune will probably be too dim to see in evening twilight.

Jupiter remains in Taurus, close to Aldebaran and the Hyades. It is high in the southern sky in the early evening and sets in the northwest around 2 a.m.

Saturn is spends the month in western Libra. It rises in the east at around midnight, and is visible the rest of the night.

The moon is not visible on the date of new moon because it is too close to the sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise. It is visible low in the west an evening or two after new moon.

Thu., December 20, 12:19 a.m. EST

First Quarter Moon

The first quarter moon rises around 11:45 a.m. and sets around 12:30 a.m. It dominates the evening sky

Its Sinhala (Buddhist) name is unduvap. The full moon rises around sunset and sets around sunrise, the only night in the month when the moon is in the sky all night long. The rest of the month, the moon spends at least some time in the daytime sky.


Observing Highlights

Sun., December 2, 9 p.m. EST

Jupiter at opposition

Jupiter is directly opposite the sun and, as a result, shines brightly all night long. Because Jupiter is above the horizon for longer than its rotation period, it is possible to watch an entire rotation of the planet in one night. Jupiter joins a circle of seven of the brightest stars in the sky: Sirius, Procyon, Pollux, Castor, Capella, Aldebaran, and Rigel, with Betelgeuse at its center.

Tue., December 4, dawn

Mercury at greatest elongation west

The best morning apparition of the year for the elusive planet Mercury. Venus and Saturn will point to the tiny glimmer of Mercury, best seen about an hour before sunrise.

Sun., December 9, 3 a.m. EST

Vesta at opposition

Now that Ceres has been promoted from an asteroid to a dwarf planet, Vesta has become the largest and brightest of the asteroids. Tonight, at magnitude 6.2, it is slightly too faint to be visible naked eye, but is an easy object in binoculars.

Tue., December 11, dawn

Mercury,  Venus and the moon

The slender waning crescent moon passes just below Venus, with Mercury nearby.

Fri., December 14, midnight–dawn

Geminid meteor shower

One of the finest meteor showers of the year, without a moon to block the view.

Tue., December 18, 4 a.m. EST

Ceres at opposition

Once the largest asteroid, Ceres has now been reclassified as a dwarf planet. At magnitude 6.6, it is an easy target in binoculars. Notice that Ceres is close to Vesta in the sky. The Dawn spacecraft, after spending nearly 14 months studying Vesta, left on September 5 to rendezvous with Ceres in February 2015.

Tue., December 25, 7 p.m. EST

Jupiter and the moon

The moon will pass just south of Jupiter soon after moonrise in the eastern sky. The two brightest star clusters in the sky, the Hyades and the Pleiades, are nearby.


Planets


Mercury will be well placed in the morning sky for observers in the northern hemisphere for the first half of the month.

Venus is still a morning “star,” shining brightly before sunrise. It moves from Libra through Scorpius into Ophiuchus during the month, sinking lower into morning twilight as it moves towards superior conjunction with the Sun on March 28.

Mars has faded into the west moving behind the sun. It moves from Sagittarius into Capricornus on December 25.

Jupiter is in Taurus, close to Aldebaran and the Hyades. It reaches opposition on December 2 and is visible all night long.

Saturn is now a morning star. It begins the month in Virgo, but moves into Libra on December 6.

Uranus is visible all evening in Pisces. It sets around 1 a.m.

Neptune remains in the depths of Aquarius all month, and sets around 10 p.m.
