This is one of those weeks you'll want to step outside every clear evening. After a New Moon on Saturday, a slim crescent reappears in the western twilight on Sunday 17 May, hanging near brilliant Venus just above the horizon. On Monday 18 May, the crescent sits almost directly alongside Venus — BBC Sky at Night calls this pairing one of the prettiest sights of the planet's entire 2026 apparition. And on Tuesday 19 May, the Moon glides between Venus and Jupiter, all three strung out in a perfect line across the darkening sky.
No equipment needed — just look west about an hour after sunset (from around 22:00 BST) and you'll see the show for yourself. This is exactly the kind of sight that turns a casual glance skyward into a lifelong love of stargazing.
The Moon plays a starring role both as a pre-dawn guide and an evening showpiece. We begin Wednesday with a slender waning crescent (just 13% lit) rising in the east around 03:30 BST — ideally placed near Saturn if you're up early enough. By Thursday the crescent is thinner still, with beautiful earthshine (the ghostly blue-grey glow on the Moon's dark side) visible to the naked eye. New Moon arrives on Saturday 16 May at 21:01 BST, delivering the month's darkest skies.
Then the waxing crescent returns to the evening sky — and what a return. On Sunday 17 May it appears low in the west near Venus. Monday 18 May brings the pair even closer. And by Tuesday 19 May, the crescent Moon sits gracefully between Venus and Jupiter, completing one of the finest naked-eye sights of the year.
Wednesday through Friday offer some of the best deep-sky observing of the month — moonless skies, galaxy season still in its final act, and the spring constellations high overhead. It's also worth getting out after New Moon on Saturday even if it's late; any clear window is precious.
