Venus hits its brightest for 2026 on September 18 — catch it low in the west now

Venus is about to be the brightest it gets all year. On the evening of September 18, 2026, it reaches greatest brilliancy at about magnitude −4.8, outshining everything in the sky except the Sun and Moon. The catch, if you’re watching from the eastern Mediterranean like I am at 35°N, is that this is a low, quick apparition: Venus sits close to the western horizon after sunset and drops out of view inside about an hour. You don’t need any gear — it’s a naked-eye object that punches straight through city light — but you do need a clear line to the west-southwest and the discipline to be outside on time. The best single evening is September 14, when a thin crescent Moon parks within 5° of it. ...

Moon phases, explained: how the lunar cycle sets your dark-sky nights

The single biggest thing standing between you and a good night under the stars isn’t your gear, your location, or even the weather. It’s the Moon. A full Moon can raise the brightness of the whole sky enough to erase the Milky Way, wash out every meteor fainter than a fireball, and flatten a galaxy into a grey smudge. A week later the same sky, from the same spot, with the same eyes, shows all of it. Nothing changed but the phase. ...

How to keep dew off your telescope: shields, heater straps, and when you need them

Somewhere in the next few weeks the first properly damp night of autumn will cut an observing session short, and it won’t be cloud that does it. A film of water forms on the front of the telescope, the stars go soft, then milky, then gone, and you spend twenty minutes with a battery hairdryer wondering where the sky went. That’s dew, and it’s the most avoidable way to lose a clear night. Here’s what forms it, what stops it, and where you can stop spending — because the cheapest fix is often enough, and some of you don’t need to buy anything at all. ...

Comet 220P/McNaught: a twice-erupting binocular comet in the pre-dawn sky

There’s a comet in the pre-dawn sky right now that most people will never hear about, because it isn’t the kind that makes the news. Comet 220P/McNaught is a small periodic visitor that has done something unusual twice this summer: it blew up. Two separate outbursts, in late May and again on August 5, dragged a 17th-magnitude speck up into binocular range. In mid-August it was sitting around 6th to 7th magnitude, low in the constellation Cetus before sunrise: a binocular object under a dark sky, and already fading. If you want it, this is the week to try. ...

The 2026 Perseids under a new moon: what the peak night gave me from Troodos

The 2026 Perseids peaked overnight on August 12–13 under a new moon, and I drove up to Troodos to catch the plateau’s rise before the sky brightened. The number first: in the darkest hour, with the radiant past 60° altitude, I counted just over 40 meteors. That’s not a storm, but it’s the most I’ve logged from a Perseid night since 2021, and the sky earned every one — no Moon, no haze, and a horizon dark enough to watch the Perseus radiant climb out of the northeast on its own. ...

Your first meteor shower: how to watch the 2026 Perseids with no gear

If you’ve never sat out on purpose to watch a meteor shower, the night of August 12 into the morning of August 13 is the one to start with. The Perseids peak then, and this year the Moon is new, so there’s no moonlight to drown the fainter streaks. It’s the darkest Perseid peak since 2021. You don’t need a telescope, binoculars, an app, or any skill you don’t already have. You need somewhere reasonably dark, something to lie back on, and about an hour of patience. Here’s exactly what to do with it. ...

Perseids 2026: a moonless peak on August 12–13, the best in five years

The Perseids peak overnight on August 12–13, and this year the Moon stays out of the way entirely. It turns new on August 12 at 17:37 UT, so the peak night is as dark as any night gets. That combination, the richest summer shower landing on a moonless sky, is what observers wait years for, and it hasn’t happened since 2021. If you clear a single night for meteors in 2026, make it this one. Here’s when to be out, where to point your eyes, and why the eclipse dominating everyone’s calendar that same day is, for those of us in the eastern Mediterranean, the less interesting half of August 12. ...

Your first two eyepieces: what focal length and exit pupil actually mean

The two most useful eyepieces you can own probably aren’t the two that came in the box, and choosing them takes two numbers, not brand loyalty. Your telescope most likely arrived with a 25mm and a 10mm eyepiece. This piece is about what those millimetres actually do, why the 10mm is so uncomfortable to look through, and which two eyepieces to add first so you cover the sky from wide star fields to the cloud belts on Jupiter. No “best eyepiece” ranking. Just the arithmetic, worked on the scopes beginners actually buy. ...

How to watch the August 12 solar eclipse safely (and what you'll actually see)

From my balcony in Nicosia I’ll see nothing on August 12. The Moon’s shadow doesn’t reach the eastern Mediterranean, so from Cyprus the Moon never crosses the solar disc at all. This is the guide I’d hand a friend who can get themselves somewhere the eclipse actually happens, whether that’s the path of totality across northern Spain or a deep partial from a back garden in London. One rule matters more than everything below it: until the Sun is 100% covered, you look through a certified solar filter or you don’t look at all. Not at 90 percent, not at 99. And if you aren’t standing inside the narrow path of totality, that means filters on for the whole eclipse, first bite to last. Everything else here is built around that line. ...

May 31 brings a Blue Micromoon — the smallest full moon of 2026

On May 31 at 08:45 UTC, the Moon reaches full phase for the second time this month. That second-in-a-month qualifier makes it a Blue Moon by the modern calendar definition. It also happens to sit near apogee — 406,135 km from Earth — making it a Micromoon: roughly 5.5% smaller in angular diameter and about 10% dimmer than an average full moon. It’s the most distant full moon of 2026. And if you walk outside that night expecting something visibly unusual, you’ll be disappointed. ...
