Black moon August 22: a rare cosmic event you can't miss — what it is, when and where to see it
As a seasonal Black Moon—the third new moon in a summer season with four—its dark side faces Earth, leaving the sky unusually clear.
This makes it a perfect opportunity for stargazers and astrophotographers to spot the Milky Way, distant star clusters, and nebulae without moonlight interference.
For the first glimpse of the Moon itself, look to the western horizon on August 24–25 just after sunset, when the thin crescent reappears.
Skywatchers are gearing up for a rare lunar event this week: a Black Moon occurring on August 22–23, 2025. While the term might sound mysterious, a Black Moon isn't something that literally appears in the sky—it's an astronomical anomaly tied to the Moon's cycles.

What is a Black Moon?
The term 'Black Moon' is popular rather than official, similar to how 'Blue Moon' is used for unusual full moons. It marks rare occurrences of new moons, and astronomers generally recognize two types:
Monthly Black Moon:
The second new moon in a single calendar month, appearing roughly every 29 months.
Seasonal Black Moon
:
The third new moon in an astronomical season that unusually contains four new moons—a rarer event, happening approximately every 33 months.
The August 2025 Black Moon is a
seasonal Black Moon
, falling in the summer season that unusually has four new moons.
Timing: When and Where to Watch
This
seasonal Black Moon
peaks at
2:06 a.m. EDT / 11:06 p.m. PDT on August 22
for U.S. observers, though the official UTC peak is
6:06 a.m. on August 23
. Unlike full moons, a new moon—and therefore a Black Moon—is
completely invisible
, since its sunlit side faces away from Earth.
Monthly Black Moons, which are less common, won't occur again until
August 31, 2027
, making this year's seasonal event a special opportunity for sky enthusiasts.
Why the Black Moon Matters Even Though It's Invisible
You might wonder: if the Black Moon itself can't be seen, why should stargazers care? The answer lies in darkness.
Optimal Stargazing Conditions:
With no moonlight washing out the sky,
Milky Way stars, distant nebulae, and star clusters
become much more visible.
Meteor Watching:
If a meteor shower happens around this time, the dark skies dramatically improve the chances of spotting shooting stars.
Photography Opportunities:
Amateur and professional astrophotographers can capture deep-sky objects without the usual lunar interference.
In short, a Black Moon isn't about seeing the Moon—it's about seeing
everything else in the night sky
more clearly.
How to Observe the Aftermath
While the Black Moon itself remains invisible, its aftermath offers a subtle but beautiful display. On the evenings of
August 24 and 25
, look toward the
western horizon 30–40 minutes after sunset
. The first thin crescent of the Moon will reappear, signaling the start of the next lunar cycle.
Tips for the best viewing experience:
Choose locations
far from city lights
to reduce light pollution.
Bring binoculars or a small telescope to enhance visibility of distant star clusters.
Check local times for sunset to synchronize your observations.

window to the cosmos
that happens only a few times a decade. With minimal light interference, this event offers some of the clearest night skies of the year—perfect for observing galaxies, nebulae, and meteor activity.
Mark your calendar, head to a dark-sky location, and let the Black Moon guide your gaze to the stars beyond.
FAQs:
Q1:
What is a Black Moon August 22–23?
A:
A seasonal new moon, invisible, offering darker skies for stargazing.
Q2:
When can I see the crescent after the Black Moon?
A:
Look on August 24–25 evenings toward the western horizon after sunset.

It's growing! Astronomers spot strange structure in the heart of Milky Way galaxy
Astronomers from Sweden's Chalmers University of Technology have made a remarkable discovery in our Milky Way galaxy: an immense structure is an expanding bubble of gas and dust surrounding the red supergiant star DFK 52. This newly detected structure is the largest of its kind ever seen, stretching an astonishing 1.4 light-years from its host star and containing nearly as much mass as the scientific team, led by Mark Siebert, used the ALMA radio telescope in Chile to observe DFK 52, a star considered a near twin to the famous Betelgeuse in Orion. To their astonishment, the data revealed the star enveloped in a sprawling, chaotic bubble, an unexpected sight, even for experts accustomed to the dramatic lives of supergiant stars. 'We got a big surprise when we saw what ALMA was showing us. The star is more or less a twin of Betelgeuse, but it's surrounded by a vast, messy bubble of material,' Siebert reported. ALMA's sensitive radio measurements allowed scientists to observe the cloud's expansion. (Photo: Getty) The bubble's mass is roughly equal to the Sun's and, if DFK 52 were as close as Betelgeuse is to Earth, it would dominate our sky, spanning a third of the full Moon's sensitive radio measurements allowed scientists to observe the cloud's expansion, pointing to a dramatic outburst about 4,000 years ago when the star ejected part of its outer layers in a massive eruption.'The bubble is made of material that used to be part of the star. It must have been ejected in a dramatic event, an explosion,' explained astronomer Elvire De Beck. The cause of such a huge ejection, without the star itself going supernova, remains a puzzle. One possibility: a hidden companion star may have helped DFK 52 shed its supergiants like DFK 52 are thought to be in the final stages of their lives, destined to explode as supernovae. Could this star be the next to light up our galaxy? 'If this is a typical red supergiant, it could explode sometime in the next million years,' says De team plans further observations to unravel the mysteries of this extraordinary structure and better understand the final acts of colossal stars.- EndsTrending Reel

We all live on this tiny dot: Earth and moon seen from 290 million km away
Nasa's ambitious Psyche mission, now more than halfway on its journey to the metal-rich asteroid Psyche, has delivered a spectacular milestone: it captured Earth and the Moon as sparkling dots from a staggering distance of about 290 million kilometers photographs were taken during scheduled checkouts of the spacecraft's science instruments, crucial for calibrating its sensitive cameras ahead of Psyche's planned arrival at its namesake asteroid in July 20 and 23, Psyche's twin multispectral imagers, equipped with telescopic lenses and specialized filters, snapped a sequence of long-exposure images, some as long as 10 seconds, showing Earth and the Moon glimmering against a backdrop of stars in the constellation Aries. When choosing targets for the imager testing, scientists look for bodies that shine with reflected sunlight, just as the asteroid Psyche does. (Photo: Nasa) These tests are more than just a photo opportunity; they're essential for ensuring that the spacecraft's imaging instruments are working flawlessly for their upcoming main task: studying the surface of asteroid Psyche in intricate like the ones aboard Psyche reveal the color and spectral 'fingerprints' of planetary bodies, offering scientists valuable information about their training its cameras on familiar targets such as Earth, the Moon, Jupiter, and Mars, each boasting known spectral signatures, engineers can compare the new data from Psyche with previous mission data, checking both the accuracy and consistency of instrument Psyche team, led by Jim Bell of Arizona State University, likens the process to collecting 'solar system trading cards,' using images of well-known celestial objects to fine-tune and validate the instruments.'We may look at Saturn or Vesta next to continue to test the imagers,' Bell remarked, hinting at ongoing preparations before the Psyche spacecraft reaches its primary target. These recent checkouts also included successful tests of the probe's magnetometer and gamma-ray and neutron spectrometer. 'We are up and running, and everything is working well,' reported Bob Mase, the mission's project manager at Nasa's Jet Propulsion up, Psyche is set for a gravity-assist flyby of Mars in May 2026—another crucial step as it hurtles through two solar orbits and covers over 1.6 billion kilometers since its October 2023 each milestone, Psyche draws closer to unlocking the secrets of metallic worlds and the early days of our solar system.- Ends
