Looking at the sky in August is a habit that comes back every summer. The nights are longer, the climate is mild and no complex tools are needed to observe phenomena that can really surprise. Also in 2025, the summer sky is preparing to offer several appointments to be marked on the agenda: shooting stars, very close planets and passages of the moon not to be missed. Here’s what will happen and when it is better to observe.
The month of desires: the peak of the Perseids
August has always been considered the privileged month to admire the falling stars with the return of the Perseidthe rain of the meteor that animates the nights of August every year. The peak is expected between the 12 and 13 August (and not on August 10 as tradition wants) but visibility will be reduced due to the Full moon which reaches the maximum the August 9th And it will remain bright in the following days. This means that many meteors, especially the weakest, risk not being visible.
To try to observe at least the brightest ones, the advice is simple: to wake up very soon, among the 2 and 5 in the morningwhen the moon lowers on the horizon. Choosing areas far from artificial lights is fundamental. In Italy, the darkest skies are found in national parks, on the Alps, in the Apennines or long isolated sections of the coast.
Conjunctions between planets
Those who are willing to wake up soon will also be able to see something rare: among the11 and 12 August, Venus and Jupiter will be visible very close to each other Towards east, just before the sunrise. They will appear as two almost overlapping brilliant points: it is an easy to identify show even without tools.
The August 6thon the other hand, there will be one Conjunction between Saturn and Neptunemore difficult to observe because it requires a small telescope. But those who have one will be able to see both planets in the same visual field: a rather rare astronomical event.
The full moon of the historian
The August moon will get noticed on several occasions. In addition to Full of August 9thalso called “Sturgeon Moon”, There will be two other moments to keep an eye on.
The 23 Augustwith the New moonthe sky will be much darker: an excellent opportunity for those who want to observe constellations, nebulae or simply the night sky in all its intensity.
Finally, the August 26ththe growing moon will pass Near Marsat an apparent distance of about 2.5 degrees. They will both be visible in the constellation of the Virgin, even with a naked eye or with a binoculars.
Testo of Titan and other details to be observed with a telescope
Those who own a telescope or attend an observatory will be able to follow two interesting events: the 3 and 19 Augustthe Titan moon (Saturn satellite) will project its shadow on the planet, a phenomenon known as transit of shadow. Other moons such as Encelado and Teti will also be involved, in particular on August 3.
Deep sky: comets and nebulas visible in summer
There is no lack of more distant and fascinating objects, especially visible with tools such as powerful binoculars or telescopes.
During August 2025 the comet will be traceable 3i/Atlaseven if it will not be visible to the naked eye. It will travel the constellations of Ofiucho, Scorpio and Libra. Those who love the most technical observation can try to follow it with pointing systems.
The most accessible is the Handbug Nebula (m27)located in the constellation of the fox. It is visible for most of the night with a 10 × 50 binoculars, and is part of the so -called Summer triangletogether with the stars Deneb, Vega and Altair.
Where to observe the sky in Italy and how to prepare
To fully enjoy the celestial show, you don’t need to be experts. But some tricks can make a difference:
Many Italian astronomical observers organize events, evenings and night walks on the occasion of the Perseids or planetary conjunctions. It is also worth inquiring locally.
