September 2026 Astrology: Neptune Sextile Pluto

September 2026 is a month when the sky evolves in a constructive direction after an intense eclipse season. There are still oppositions and squares; life flows on as usual with its good days, bad days, and unexpected turns. But beneath it all, something is moving forward constructively. The outermost planets of our solar system, Neptune and Pluto, perfect an exact sextile this month. The lunar cycles are also particularly supportive. And there are enough planetary movements and sign ingresses that we can finally feel the story moving forward.

Let's look together at this month's most important transits.

Venus Enters Its Shadow Phase: A Time to Deepen Relationships

On September 1st, Venus reaches 22° Libra, stepping into the shadow degree of its upcoming retrograde. The retrograde begins on October 3rd at 8° Scorpio and ends on November 13th at 22° Libra. Venus will spend an extended period in this zone (22° Libra-8° Scorpio) until December 16th. Pay attention to anything that comes up around September 1st: a feeling, a discomfort, a relationship dynamic... Something you're holding onto that resurfaces. This will likely be the theme Venus wants you to work on until December.

Mercury and Venus Change Signs: Diving into Relationship Waters

On September 10th, the inner planets Mercury and Venus change signs: Mercury moves into Libra, and Venus moves into Scorpio. Both step into both the relationship and shadow zones. Because relationships confront us with the 'other', with the mirror, and with parts of ourselves that can only be understood and awakened through reflection. This process is never easy, because the mirror is never neutral. When things heat up, and you find yourself caught in old patterns, remember: this is the price of admission to true intimacy, and it's worth it.

New Moon in Virgo: Practical Steps and Clarity

On September 11th, a New Moon occurs at 18° Virgo. This supportive Moon forms a tight sextile with Mars. The New Moon's ruler, Mercury, is in the early degrees of Libra, making trines to Uranus and Pluto, and is in good shape. After the eclipse season, whatever we've seen, it's time to clarify what needs to be done in the real world. Virgo knows better than anyone how to turn what 'makes sense' into what 'really works'.

Uranus Stations Retrograde: Signals of a New Era

On the same day, September 11th, Uranus stations retrograde at 5° Gemini. As with outer planets always, more attention should be paid to the station moments than to their aspects. Uranus is still fresh in Gemini, in the getting-to-know-each-other phase. Therefore, the station, especially in the context of the New Moon, may feel like Uranus is raising its voice for the Gemini agenda. We may get a clear clue about what the next seven years are really about.

Mercury Connects to Generational Aspects: Seeing the Big Picture

On September 12-14, Mercury, reaching 3-5° Libra, connects to the generational architecture. We've talked a lot about what it means for Uranus, Neptune, and Pluto to be in new signs and in aspect to each other. However, unless activated by a personal planet like Mercury, all of this remains somewhat abstract. We're so used to seeing our thoughts and inner dialogue as the only reality... But the fact is, our poor Mercury, left to its own devices, often misses the meaning. Taking into account other perspectives, how events are actually unfolding on a much larger scale, and how it fits into a bigger picture, is both humbling and liberating. This Mercury series will take us out of the small story in our heads and connect us to a much larger reality.

Black Moon Lilith Enters Capricorn: Confronting Shadow Ambitions and Authority

On September 14th, Black Moon Lilith enters Capricorn. Lilith is the shadow of the Moon; all the emotions, impressions, and psychological complexes that never come into the light of consciousness. But that doesn't mean they disappear. They go underground, settling into the body as raw, unfiltered psychic material. Black Moon Lilith is essentially what the Moon wants when the Sun isn't looking. When this part of us enters Capricorn, it brings out the more Lilith-like aspects of the sign. Capricorn is the cardinal earth element; it tells us how we claim our ground, what we're willing to work for, and what is non-negotiable in the physical world. This can manifest as rebellion against false authority or a rediscovery of an ambition we never dared to claim. Or, conversely, it may surface as the realization that being a workaholic or competing with others is not the expression of our true passion and fulfillment, but a substitute for it.

Venus Square Pluto: The Eve of Deep Transformation

On September 15th, Venus squares Pluto at 3° Scorpio, giving a taste of the months ahead. Venus will retrograde in early October at 8° Scorpio, but it's already moving very slowly, meaning the Venus-Pluto square will be in effect for an unusually long time. We're talking about a transit lasting nearly three months. Normally, a Venus-Pluto transit lasts a few days; imagine the scale. No one can stay on the surface with this transit. During this period, deeply rooted emotions, power dynamics, and control themes may surface. This offers an opportunity for honesty and transformation in relationships.

Neptune Sextile Pluto: The Invisible Scaffolding

On September 15th, Neptune and Pluto form an exact sextile in Aries and Aquarius. This is a new version of an aspect that has repeated several times over the past decades; it's the first exact aspect while Neptune is in Aries and Pluto is in Aquarius. This perfect alignment is a celestial 'stamp' moment when the aspect crystallizes. The months and years of Neptune and Pluto dancing around each other are, in a sense, a preparation for these exact meetings. In its most direct interpretation, this is good news: Beyond our understanding, the universe has scaffolding that provides the support needed for possibility to become reality. This exact 'click' moment may be one of those times even mortals can notice. Clarity may come about how something you feel is important but can't quite grasp fits into a much larger process. Clues as to where this collaboration will begin to show up in your life are hidden in the Aquarius and Aries houses of your chart.

Chiron Returns to Aries: Healing the Last Wounds

On September 19th, Chiron returns to Aries after its brief visit to Taurus, coming here to complete its long-overdue work. We have until April 2027 to clean up and heal the themes in the Aries house; then it will move permanently into Taurus territory.

Sun Enters Libra: Equinox and New Beginnings

On September 23rd, the Sun enters Libra; happy birthday to all Libras and happy equinox to everyone! The equinox is the time of year when day and night are equal. This point of balance is also a turning point: the balance between night and day is now shifting. It brings a new season, new developments, new opportunities, and new beginnings. Although Libra is almost synonymous with the word 'balance', and balance may seem somewhat inert, let's not forget that Libra is a cardinal sign. Libra season is actually a great time to take action: put yourself out there, start intellectual projects, or forge new social connections.

Full Moon in Aries: Big Dreams and Discovery of Purpose

On September 26th, a Full Moon occurs at 3° Aries. This Full Moon, exactly conjunct Neptune, evokes what Carl Jung called the 'big dream': a numinous, archetypal dream that reveals something extraordinary about ourselves and our purpose. This means we should pay attention to messages that don't come through the usual channels. There's something trying to emerge about your purpose (Aries); a missing piece that will fit different parts of the story together. More literally, this could be a 'dreams come true' Full Moon, as it almost exactly activates the Neptune-Pluto sextile. The impersonal, transcendent realm is now becoming personal.

Mars Enters Leo: A Long and Bold Story

On September 28th, Mars leaves Cancer and enters Leo. In all astrological honesty, Mars in Cancer was not an easy transit, not just in terms of basic dignity. While Mars was in Cancer, it was squaring Neptune and Saturn, and since all the outer planets have moved into fire and air signs, it didn't get much support from water and earth elements. This should make us at least somewhat enthusiastic about Mars in Leo. Warning: Mars's first aspect will be an opposition to Pluto, and a Mars-Pluto opposition is a Mars-Pluto opposition. Still, it's softened by a trine to Neptune and a sextile to Uranus. Then things start to get interesting as Mars approaches Jupiter and the South Node. This Mars transit will be quite interesting because Mars will return to Leo next year; that is, we're talking about a much longer Mars-in-Leo story than usual. Mars will enter its retrograde shadow in Leo in November and won't complete its retrograde cycle until June 2027.

September 2026 is a month when the sky indicates deep restructuring on both personal and collective levels. Venus's shadow phase and retrograde are an invitation to review our relationships. The Neptune-Pluto sextile allows us to become aware of invisible support structures. The insights during this period will guide the months ahead. As you write your own story in this celestial dance, remember that the stars are guiding you.
