July 2026 Astronomical Events: Aphelion, Summer Milky Way, Alpha Capricornids and Southern Delta Aquariids

July 2026: longer nights, Summer Milky Way at its peak and a prelude to the Perseids

July 2026 brings good news compared to the previous month: after the Summer Solstice on 21 June, nights start growing longer again and astronomical darkness gradually reclaims more time. Compared to the solstice, the second half of the month already gains 30–50 minutes of additional darkness — enough for genuine astronomical dark skies around midnight. The planetary scene shifts dramatically: Jupiter disappears from the sky, swallowed by solar glare ahead of its conjunction on 29 July, while Saturn rises progressively earlier in the east, heading towards its October opposition, and Venus grows ever brighter in the west after sunset. The dominant visual theme is the Summer Milky Way, which reaches its greatest splendour in July with the galactic core in Sagittarius well positioned on the meridian during the central hours of the night. On the agenda: the Earth's aphelion on 6 July, the spectacular morning scene on 11 July with the Moon, Mars and the Pleiades, the near-occultation of Antares on 24 July, and the double meteor peak at month's end with the Alpha Capricornids and Southern Delta Aquariids.

Moon phases and observing planning

The distribution of moon phases in July 2026 strongly favours the first half of the month for deep-sky observing. After the Last Quarter on 7 July, the sky darkens quickly towards the New Moon on 14 July (11:43 CEST): the window between 10 and 18 July provides the best conditions of the month, with nights already noticeably longer than at the solstice. In the second half of the month the Moon returns as the dominant player, reaching the First Quarter on 21 July and the Full Moon on 29 July (16:35 CEST) to close out the month.

• 7 July: Last Quarter
• 14 July: New Moon (11:43 CEST) — Moon near perigee: 360,141 km
• 21 July: First Quarter
• 29 July: Full Moon (16:35 CEST) — Buck Moon

The Full Moon of 29 July is traditionally called the Buck Moon, a name of Algonquin origin referring to the time of year when male deer antlers reach their full growth. From a Northern Italy observing perspective, this Full Moon will sit unusually low on the southern horizon: in midsummer the Full Moon — opposite the Sun — lies in the constellation Capricornus, mirroring the Sun's low winter altitude. The visual effect is a large, orange-tinted Moon hugging the horizon — particularly photogenic above coastal or lagoon landscapes.

An important planning note: 29 July also coincides with Jupiter's solar conjunction. The gas giant is completely invisible for the entire month of July. It returns to the morning sky from August onward, with progressively improving visibility building towards the major event of 12 August 2026 — total solar eclipse, planetary alignment and Perseid maximum.

6 July — Earth's aphelion: farthest point from the Sun

On 6 July 2026 at 18:00 UTC, the Earth reaches aphelion, the point of its elliptical orbit at maximum distance from the Sun: 152,088,063 km. The contrast with the perihelion at the start of the year (3 January, approx. 147,100,000 km) amounts to roughly 5 million km, about 3.4% greater distance.

This is an initially counterintuitive fact for those living in the Northern Hemisphere: we are at our greatest distance from the Sun right in the height of summer, while winter corresponds to the closest approach. Seasons are driven by the tilt of Earth's axis (23.4°), not by solar distance. In July the Northern Hemisphere is tilted towards the Sun, which therefore stands higher in the sky and shines for more hours. The distance difference instead affects orbital speed (Kepler's second law): near aphelion the Earth moves more slowly, which is why Northern Hemisphere summer is about four days longer than winter.

For solar imaging (with approved AstroSolar or equivalent filters): at aphelion the solar disc appears about 3% smaller than at perihelion in January. The difference is imperceptible to the naked eye but measurable in calibrated images — an interesting project for those who practise solar imaging with a dedicated telescope, comparing shots taken at perihelion and aphelion across the year.

Morning sky: Saturn, Mars, Moon and the Pleiades (6–11 July)

The first week of July offers a rich sequence of events in the pre-dawn sky, as the waning Moon crosses the zone of the morning planets. Both Saturn and Mars are visible before dawn in the east: Saturn in the constellation Pisces, Mars in Taurus.

• 6 July, approx. 2:00–4:00 am: The waning gibbous Moon (approx. 60% illuminated) passes near Neptune (magnitude 7.7) in the constellation Pisces. With binoculars or a small telescope, the bluish disc of the most distant planet is detectable; nearby shines Saturn (magnitude 0.7), easily visible to the naked eye as a steady, slightly yellowish point of light.
• 7 July, approx. 1:00 am until dawn: Last Quarter coincides with the Moon near Saturn in Pisces. The pair is visible from 1:00 am on the eastern horizon and climbs higher towards dawn. At the telescope, the half-lit Moon beside Saturn's wide-open rings — increasingly impressive as the October opposition approaches — makes for a visually rewarding target and an excellent introduction to planetary imaging.
• 11 July, approx. 4:00–5:30 am: A morning scene in Taurus not to be missed: the thin waning crescent Moon (approx. 15% illuminated), red Mars (magnitude 1.4) and the Pleiades star cluster (magnitude 1.2) all gather in the same region of sky, visible to the naked eye and fitting comfortably in the same field of a 10×50 binocular. Uranus (magnitude 5.8) is also nearby, reachable with binoculars. The reddish-brown of Mars against the blue-white of the Pleiades creates a colour contrast that suits both a wide-angle landscape shot and a 200–400 mm telephoto composition.

Saturn in July: the ringed planet is developing into the great protagonist of the autumn sky. The opposition on 4 October 2026 is still some way off, but Saturn already offers worthwhile conditions for planetary imaging in the morning hours with a dedicated camera and video stacking. The rings, progressively widening compared to recent years, deliver a detail-rich view that justifies a session even without perfect seeing. Mars at magnitude 1.4 is still far from its opposition (expected early 2027), but its characteristic reddish colour is immediately unmistakable.

Mercury, which dominated the June evening scene with its greatest eastern elongation, is in retrograde motion in July and quickly dives into the solar glare: it is unobservable for the entire month.

Venus rules the evening sky: Moon and Venus on 17 July

While Saturn and Mars command the morning sky, Venus (magnitude −3.8) is the undisputed queen of the evening sky. The brightest planet in the Solar System is visible in the west after sunset, standing progressively higher on the horizon as it heads towards its greatest eastern elongation on 15 August. From 9 July, Venus moves into the constellation Leo, blazing in the twilight hours with unmistakable brilliance.

17 July: the waxing crescent Moon (approx. 15–20% illuminated) passes near Venus in the evening sky. A slender crescent beside the sky's brightest planet is one of the most photogenic subjects in amateur astronomy — perfect for tripod photography with a wide-angle lens, including the twilight-lit western horizon. With a 200 mm or longer telephoto, the crescent and Venus disc share the same frame for particularly striking images.

At the telescope, Venus in July displays a clearly visible phase: still before greatest elongation, the disc is no longer a mere point but shows a phase between half and gibbous that grows progressively. July 2026 is one of the best viewing opportunities of the year for observing Venus's phase at the telescope: the planet stands high in the evening sky, the phase is well defined, and available observing hours after sunset are ample for a relaxed session. Even a 60–80 mm refractor at 50–100× reveals the phase clearly and never fails to impress.

24 July — Moon and Antares: near-occultation

On the evening of 24 July, the waning gibbous Moon (approx. 81% illuminated) closes to within just 0°33' of Antares (α Scorpii, magnitude 1.0), the brightest star in Scorpius and one of the reddest stars in the northern sky. A separation of 0°33' is roughly one lunar diameter: the star grazes the Moon's limb in a near-occultation of great visual impact.

The name Antares — from the Greek meaning «rival of Mars» — derives from its pronounced orange-red colour and brightness comparable to the Red Planet. It is a red supergiant so enormous in diameter that it would encompass the entire orbit of Mars around the Sun — an object that combines visual beauty with astronomical fascination. In some parts of the world a true lunar occultation of Antares occurs (visible from Antarctica, South Georgia and the Falkland Islands), while from Italy the star grazes the lunar limb in a spectacular near-occultation.

Through 10×50 binoculars the scene is impressive: the nearly full Moon beside the orange-red Antares, against the rich backdrop of Scorpius. At the telescope, in moments of good seeing, the gradual approach and then recession of the Moon from the star can be followed in real time. Approximate timing for Northern Italy: the pair becomes visible after dark around 10:00 pm CEST low on the south-south-eastern horizon, with the closest approach in the hours that follow. Check the precise time for your location using software such as Stellarium.

Meteor showers: Alpha Capricornids, Southern Delta Aquariids and Perseid prelude

July is the transition month into the great summer meteor season. As the Meteor Section of the Unione Astrofili Italiani (UAI) reports, July 2026 is characterised by a particularly favourable first half of the month — thanks to the waning Moon and the New Moon on 14 July — while the second half is hampered by increasing moonlight building to the Full Moon on 29 July.

• Alpha Capricornids (CAP) — Main players of the month alongside the Delta Aquariids. The Zenithal Hourly Rate (ZHR) is modest, rarely exceeding 5–10 meteors per hour, but this shower is renowned for its spectacular, very bright fireballs, often visible even from light-polluted urban areas. The meteors appear to radiate from the constellation Capricornus and are particularly impressive in the central hours of the night when the radiant is high enough above the southern horizon. The peak falls between the third week of July and 31 July, with the maximum around 30 July.
• Southern Delta Aquariids (SDA) — The main shower of July–August, with a theoretical peak rate of 20–25 meteors per hour under ideal conditions, generally fast meteors with frequent persistent trains. Unfortunately the double peak on 30–31 July 2026 falls near the Full Moon on 29 July, severely reducing visual detection of fainter meteors. Radio observers — a method widely practised within the UAI — can monitor the activity without any lunar constraints. The first half of July, when the shower is already partially active, provides the best conditions for visual observing under dark skies.
• Minor showers and Perseid prelude — The UAI Meteor Section highlights the following additional streams: Mu Lyrids and Kappa Lyrids (radiant well-placed for the Northern Hemisphere, with occasional bright meteors before dawn); Xi Perseids and Theta Perseids (a direct prelude to the August Perseids, radiant in the Perseus region); Zeta Draconids, July Gamma Draconids and Omicron Draconids (circumpolar streams of scientific interest); Omicron Cygnids (radiant embedded in the Cygnus Milky Way). As the month progresses, Perseid activity begins to build noticeably: from mid-July onward, fast meteors from the direction of Perseus can already be caught as a pleasing foretaste of the great August peak.

2026 observing strategy: focus visual sessions on the first half of the month (10–20 July), after midnight when the Earth is oriented into the direction of its orbital motion and intercepts the greatest number of meteoroids. The Alpha Capricornids can deliver fireballs at any time of the month, even with the Moon present. For video capture of the full night's meteor activity, a fixed camera with a fisheye or wide-angle lens (24 mm or shorter) pointed at the zenith is the ideal setup for all-night timelapse recording.

Deep-sky in July: Summer Milky Way, Sagittarius and Scorpius

The week centred on the New Moon of 14 July is the best observing window of the month — and one of the finest of the year — for the Summer Milky Way. Unlike June, where the brevity of nights and persistent twilight restricted access to Sagittarius, in July the galactic core reaches appreciable altitudes above the southern horizon during the central hours of the night from Northern Italy. Nights are already 40–50 minutes longer than at the solstice.

• Summer Milky Way — galactic core — The field spanning Sagittarius, Scutum and Aquila is the densest stellar region in the boreal sky. Through 10×50 binoculars or a wide-field telescope, star clouds, emission nebulae and overlapping clusters emerge in a way that has no equal anywhere else. For wide-angle astrophotography (≤50 mm), July is the prime month for the Milky Way from Northern Italy, with the galactic core well positioned on the meridian between midnight and 2:00 am.
• M8 (Lagoon Nebula) and M20 (Trifid Nebula) — The two most photographed nebulae in Sagittarius now become accessible. They require a clear southern horizon (they culminate at roughly 18°–22° altitude from latitudes 44°–46°N) and benefit from narrow-band H-alpha filters to compensate for atmospheric extinction at low elevation.
• M22 (globular cluster in Sagittarius) and M24 (Sagittarius Star Cloud) — M22 is one of the richest globular clusters in the sky, often overlooked in favour of M13; M24 is an astronomically extraordinary star field, best appreciated at low magnification and wide field of view. Both are ideally placed in July.
• M11 (Wild Duck Cluster) — In Scutum, at the edge of the Summer Milky Way, it is one of the richest open clusters in the sky: a 80–100 mm telescope resolves it into hundreds of stars across a field of about 14' — spectacular both visually and photographically.
• M4, M6, M7 (Scorpius) — Scorpius stands high on the southern horizon in the early hours of the night. M4 is the nearest globular cluster to Earth (~7,200 light-years), with a structure resolvable even in an 80 mm instrument; M6 (Butterfly Cluster) and M7 (Ptolemy Cluster) are bright open clusters with rich structure, perfect for binoculars or a low-power telescope.
• M13 (Hercules) — Still well placed on July evenings, the Great Globular Cluster in Hercules remains the reference target for those wishing to accumulate multi-night integration with an apochromatic refractor. Its high position near the zenith minimises extinction, making it the ideal subject for accumulating sessions around the New Moon.

The optimal strategy for July is to combine zenith and southern targets: start with M13 and Lyra (M57, Ring Nebula) as the sky darkens after sunset, then swing towards Sagittarius and Scorpius from midnight onward as the galactic core transits the meridian. Narrow-band H-alpha filters (7 nm or tighter) effectively offset both residual twilight in the early hours of the night and the artificial sky background at low-altitude observing sites in the Po Valley and coastal areas.

Common mistakes to avoid

July 2026 is the month of transition: nights are growing longer, the Summer Milky Way reaches its peak and the events calendar spreads observing appointments from pre-dawn to after dusk — from Saturn and Mars at sunrise to Venus and the Moon at sunset, taking in the Earth's aphelion, the near-occultation of Antares and the summer's meteoritic prelude. The countdown now points firmly to August 2026, where the total solar eclipse on 12th, the return of Jupiter and the Perseid maximum promise one of the most astronomically intense months of the year — but July already deserves the deckchair and binoculars outside the front door.
