The moment of new moon will fall at 6:06 UTC on August 23, 2025. That’s 1:06 a.m. CDT. Many will call this moon a Black Moon. In this video, EarthSky’s Deborah Byrd explains what makes Black Moons so special! Watch in the player above, or on YouTube.
Now’s the time to see Mercury! Look for more planets, too
Mercury has come into view in the east before dawn, below the 2 bright planets Venus and Jupiter. It reached its greatest elongation – its farthest distance from the sun in the morning sky – at 10 UTC on August 19. Also, the moon will sweep past all 3 planets! And these aren’t the only planets in the morning sky. Get your planet and moon info for the week here! Deborah Byrd hosts. View here or on YouTube.
Late August mornings: 4 visible planets
In the last few weeks of August, there will be 4 planets in the early morning sky. Here’s the view of Mercury, Venus, Jupiter and Saturn as viewed from the Northern Hemisphere. You can catch Venus and Jupiter before dawn. Mercury might be visible in the morning twilight. Saturn is visible most the night. And the planets all lie along the ecliptic, the path the sun travels in the daytime (the green line on our chart). Chart via EarthSky.

August 25 and 26 evenings: Moon, Mars and Spica
Shortly after sunset on August 25, the thin waxing crescent moon moon will float just above the western horizon. It will lie near Mars in the evening twilight. Nearby is the bright star Spica, the brightest star in Virgo. Then, on the following evening, the crescent moon – full with earthshine – will shine between Mars and Spica. Chart via EarthSky.

August 27 evening: Moon and Spica
As darkness falls on August 27, a waxing crescent moon and the bright star Spica will lie low on the southwestern horizon. What’s more, a few lucky observers in parts of South America and Antarctica will see the moon occult – or pass in front of – Spica at 15 UTC on August 27. If you look outside then and don’t see Spica … that might be because it’s behind the moon! Details on the occultation here. Chart via EarthSky.
August 29: Moon reaches apogee
The moon will reach apogee – its farthest distance from Earth for the second time this month in its elliptical orbit – at 16 UTC on August 29, 2025, when it’s 251,374 miles (404,548 km) away.
August 28 and 29 evenings: Moon near Zubenelgenubi
On the evenings of August 28 and 29, the waxing crescent moon will float near a star with a strange sounding name – Zubenelgenubi – low in the south. It’s in the constellation Libra the Scales. They’ll set a few hours after sunset. Chart via EarthSky.
August 30 and 31 evenings: Moon pairs up with Antares
On the evenings of August 30 and 31, the approximately half-lit moon will approach and then pass the bright red star Antares. What’s more, a few lucky observers in parts of Africa, Madagascar, Kerguelen Islands, Antarctica and New Zealand will see the moon occult – or pass in front of – Antares at 11 UTC on August 31. If you look outside then and don’t see Antares … that might be because it’s behind the moon! Details on the occultation here. But if you don’t live where the occultation is happening and still can’t see Antares, try positioning yourself so the moon lies behind a utility pole. Now see if the star pops into view! They’ll set before midnight. Chart via EarthSky.
If you’re out stargazing on any August evening, look for these stars and constellations overhead in the evening sky.
If you have a dark sky, it’s easy to observe the edgewise view into our own galaxy – our Milky Way – spanning across the heavens. Need help finding it? Look toward the constellation Cygnus the Swan. You might know this constellation by its asterism, the Northern Cross. The Swan swims along the Milky Way. Its brightest star is Deneb, the Swan’s Tail. Additionally, the constellation Cygnus contains one of the most beloved double stars in the sky, Albireo, which appears blue and gold.The constellation Lyra the Harp is another summer favorite. It consists of a triangle and a parallelogram. Its brightest star is Vega. Then, look next to it for the famous Epsilon Lyrae, the Double Double Star, really 4 stars in all.Aquila the Eagle is home to the star Altair, which is one of the corners of the Summer Triangle. In addition, you can also use Aquila to starhop your way to the Wild Duck Cluster in Scutum. Image via EarthSky.This chart shows the 3 stars of the Summer Triangle in the evening sky, looking east. Note the size of Vega’s constellation, Lyra. So the Summer Triangle is big! A 12-inch (1/3-meter) ruler, placed at an arm’s length from your eye, will span the approximate distance from Vega to the star Altair. And an outstretched hand with thumb and pinky spread will fill the gap between Vega and Deneb. You can see the Summer Triangle in the evening from around May through the end of every year.

In early August, before sunrise, brilliant Venus will lie in the east above bright Jupiter. They’ll rise a few hours before sunrise. Plus, they’ll make a dynamic duo when they will lie closest to each other around August 12, which, coincidentally, is the peak of the Perseid meteor shower. After their eye-catching close encounter, Jupiter will climb higher each day and move away from brilliant Venus. Both Venus and Jupiter will float among the stars of Gemini the Twins, with Venus moving in front of Cancer the Crab later in the month. Chart via EarthSky.In August, Saturn will shine in the south in the morning sky. Saturn is the bright object below the 4 moderately bright stars that make up the Great Square of Pegasus asterism. Saturn will be rising about an hour after sunset by month’s end and shining at 0.7 magnitude. Saturn shines in the constellation of Pisces the Fish this month. And Saturn will reach opposition – when we fly between it and the sun – in September. It’ll be brightest around then and visible all night. Chart via EarthSky.In late August, for Northern Hemisphere viewers, brilliant Venus and bright Jupiter will lie near Mercury. Mercury will reach its greatest distance from the morning sun – or greatest western elongation – at 10 UTC on August 19. It will be 19 degrees from the sun then. And Mercury moves from the constellation of Cancer the Crab to Leo the Lion this month. Chart via EarthSky.

Marcy taught astronomy at her local community college for over 20 years. She and her husband live in Wyoming, in a rural location, with an all-sky camera and super-good horizon views! And, their observatory will soon be ready to photograph the night sky.
“I can sometimes see the moon in the daytime” was a cosmic revelation that John Jardine Goss first discovered through personal observations at age 6. It shook his young concept of the universe and launched his interest in astronomy and stargazing, a fascination he still holds today. John is past president of the Astronomical League, the largest U.S. federation of astronomical societies, with over 24,000 members. He's earned the title of Master Observer and is a regular contributor to the video series, “Global Star Party.” He has authored the celestial observing guides “Exploring the Starry Realm,” and “Carpe Lunam,” and “Take Your First Steps, an Introduction to Amateur Astronomy.” John also wrote for twenty years the monthly stargazing column, Roanoke Skies, for the Roanoke Times, and currently writes a bimonthly column, Skywatch, for Blue Ridge Country magazine. He has contributed to Sky and Telescope magazine, the IDA Nightscape, the Astronomical League’s Reflector magazine, and the RASC Observer’s Handbook.
