The moment of last quarter moon will fall at 20:31 UTC (2:31 p.m. CST) on January 21, 2025. It’ll rise after midnight your local time and set around noon. Look for it high in the sky before dawn.
The moon, close to its 3rd quarter phase, will lie near the bright star Spica on the mornings of January 20 and 21. What’s more, a few lucky observers in the Cape Verde Islands, parts of west and south Africa, and south Madagascar will see the moon occult – or pass in front of – Spica on January 21. Others will see the moon close to Spica. So, if you look outside on the morning and don’t see Spica … that might be because it’s behind the moon! Spica is the brightest star in Virgo the Maiden. They’ll rise around midnight and be visible through dawn. And it’s a good time to look for the moon in the morning daylight sky. Chart via EarthSky.

A planetary alignment on January 25?
Will the planets align on January 25, 2025? By now, you might have seen the breathless announcements claiming that they will. Is it true? Get the scoop on planets in January 2025 from EarthSky’s OB stargazers Deborah Byrd and John Goss!
Here’s the view of 4 bright planets in late January and early February 2025. They lie along the path the sun travels in daytime (the green line on our chart). As darkness falls each evening, you’ll find Venus in the west, headed toward greatest brilliancy. The steady golden light of Saturn is below Venus in the west after sunset. High overhead is bright Jupiter. And, in early evening, you’ll find the red planet Mars ascending in the east. Here’s a view of the planets from an all-sky camera in Wyoming on January 15, courtesy of EarthSky’s voice of the night sky Marcy Curran. What a planetary treat! Image via WyoAstro Observatory.
The waning crescent moon will lie close to red Antares on the morning of January 24, 2025. Antares is the brightest star in Scorpius the Scorpion. What’s more, a few lucky observers in parts of Madagascar, south Australia, south Polynesia, and New Zealand will see the moon occult – or pass in front of – Antares at 0 UTC on January 25. Others will see the moon close to Antares. So if you look outside on the morning of January 24 and don’t see Antares … that might be because it’s behind the moon! Then it will lie between Antares and the horizon on the next morning. Look for them about an hour before sunrise. Do you see a glow on the unlit portion of the moon? That’s earthshine. It’s light reflected from Earth. Chart via EarthSky.
The thin waning crescent moon will move away from Antares and will hang closer to the eastern horizon before sunrise on January 26 and 27. Look for them about 40 minutes before sunrise. Chart via EarthSky.

January 30 and 31 evenings: Moon, Venus and Saturn
The thin waxing crescent moon will hang in the bright twilight low on western horizon shortly after sunset on January 30, 2025. Brilliant Venus will shine much higher in the sky with the steady golden light of Saturn nearby. On the last evening of January, the crescent moon full with earthshine will float near Venus and will lie close to Saturn. Chart via EarthSky.
If you’re out stargazing on any January evening, look for these stars and constellations overhead in the sky.
First, look for one of the most recognizable constellations in the sky,Orion the Hunter. It’s visible in both hemispheres. It rises in the east on January evenings. The 3 bright stars in a row – Orion’s Belt – are sure to catch you eye. Chart via EarthSky.Next, look for the 5-star W or M shape of Cassiopeia the Queen. Not only is it easy to spot, it is useful to find other stars, constellations and deep-sky objects. Look for it high overhead as darkness falls in early January. Chart via EarthSky.

Stargazing tips for beginners
January morning planet
During the first half of January, Northern Hemisphere viewers can find Mercury well placed in the bright morning twilight about 30 minutes before sunrise. The little planet might be difficult to spot, but binoculars might help. The bright star Antares will shine nearby. Mercury reached its farthest distance from the sun in late December.

All-sky charts for January evening planets
Here’s the view of 4 bright planets on the evening of January 5, 2025. They will lie along the path the sun travels in daytime (the green line on our chart). If you have an unobstructed view of the sky, you can easily see all 4 of them at once. By the way, Uranus and Neptune are there as well but require optical aid to see. Brilliant Venus is a beacon in dark skies in the west with the steady golden light of Saturn nearby. Venus and Saturn were been getting closer to each other until January 17, then, they will move apart. High overhead is bright Jupiter – it’s brighter than all stars – and then the red planet Mars is in the eastern sky. Mars is visible all night and is as bright as Sirius, our brightest star.
January planet visible all night
Mars is on display this month and closing in on the bright stars Castor and Pollux. It’ll be visible all night this month. Mars was closest to Earth – about 5.3 light-minutes away – on January 12. Mars laid near the full moon on January 13 and was occulted by the moon on January 14. Then it laid opposite the sun from Earth – or at opposition – on January 15-16. It reached magnitude -1.4, matching that of Sirius, our brightest star. Mars is closest to Earth roughly every 2 years. So we won’t see Mars this bright again until 2027. Chart via EarthSky.
Venus was shining brightly after dark in the western evening sky and reached its greatest distance from the sun on January 9-10. It’ll set about 4 hours after sunset and is a beacon in a dark sky. Saturn will be there too – it’s less bright than Venus – but they’ll make a lovely pair in the evening sky as they race toward each other. Their closest approach was on the evenings of January 17-18, 2025. The planetary pair made an eye-catching sight and laid about 2.2 degrees apart at their closest. Chart via EarthSky.
Bright Jupiter will lie high in the east in the evening sky. It is surrounded by the bright stars Capella and Aldebaran, and the Pleiades and Hyades star clusters. Jupiter was at its brightest last month and will fade a bit this month. But it still outshines even the brightest stars. Jupiter will rise before sunset in January and set a few hours before sunrise by month’s end. It’ll remain in the constellation of Taurus the Bull until it passes behind the sun – in its solar conjunction – in June. Chart via EarthSky.
