The night sky is about to treat stargazers to two beautiful celestial events this week. On September 25 and again on September 27, 2025, the Moon will pair up with two fiery red objects Mars and Antares, the brilliant heart of the Scorpius constellation. These rare alignments will create stunning views that anyone with a clear sky should not miss.
September 25: Crescent Moon Between Mars and Antares
On Thursday, September 25, look to the southwestern sky just after sunset and you’ll witness a striking trio the crescent Moon, Mars, and Antares all sharing the same patch of sky.
The Moon will be about 15% illuminated, glowing softly as evening falls. On one side of it, you’ll find Mars, shining with its signature orange-red hue. On the other side will be Antares, a red supergiant star about 550 light-years away, forming the bright, beating heart of the constellation Scorpius.
This alignment isn’t just a pretty sight. It’s also a fascinating astronomical moment. The name “Antares” comes from ancient Greek, meaning “rival of Mars” a nod to how similar their colors appear to the naked eye. Seeing them both so close to the Moon perfectly highlights this ancient rivalry.
To enjoy the view, head outside about 30 to 60 minutes after sunset and look low in the southwestern sky. A clear view of the horizon is essential, as the trio will be setting not long after the Sun. Binoculars can enhance the view, but this is one of those rare astronomical scenes that you can fully appreciate with just your eyes.
September 27: The Moon Meets Antares Again
Just two nights later, on Saturday, September 27, the Moon returns for another breathtaking show this time moving even closer to Antares. The pair will appear side by side in the evening twilight, creating a beautiful contrast between the Moon’s pale light and Antares’ deep red glow.
In some parts of the world, this event will be even more dramatic. Observers in parts of the Southern Hemisphere and near Antarctica may witness a lunar occultation, where the Moon actually passes in front of Antares, hiding it from view for a short time. For most skywatchers elsewhere, including those in South Asia, Europe, and North America, the Moon and Antares will simply make a very close approach still a beautiful sight worth stepping outside for.
Once again, the best time to look is shortly after sunset, facing southwest. Because Antares sits relatively low in the sky, try to find an observing spot with minimal obstructions like trees or buildings.
Conjunctions like these are more than just a treat for the eyes they’re also reminders of our place in the cosmos. Mars is a neighboring planet orbiting just beyond Earth, while Antares is a colossal red supergiant nearing the end of its life, located hundreds of light-years away. Seeing them both close to the Moon our own celestial companion is a humbling reminder of the vast range of distances and scales in our universe.
Events like the ones on September 25 and 27 are also wonderful opportunities for beginners and seasoned skywatchers alike. They don’t require telescopes or special equipment just clear skies and a few moments to look up.
