These are the best targets to observe over the Christmas holidays.

If you’re looking for the quiet wonder of Christmas Eve, turn your gaze to the southwest sky as it gets dark. There, nicely illuminated, though not yet bright, will be a waxing crescent moon. A fifth of what you’ll see will be its day-side; the other four-fifths — its night-side — will be gently lit by sunlight reflected from our planet — Earthshine. If you have binoculars or a small telescope, point them at the terminator, that line between day and night, to see long shadows and craters in relief. Naked eye observers should look to the left of the moon for Fomalhaut (below) and Saturn (above).

Christmas Day needs a “Christmas Star,” and what better candidate than Jupiter, which tonight shines at magnitude -2.5 in the constellation Gemini. Look to the east anytime after dark, and you’ll see the giant planet close to “the twins” of Gemini — the stars Castor and Pollux — as it shines brighter than anything else in the night sky, save for the moon. Now is the ideal time to observe Jupiter, which reaches its annual opposition — when Earth is between it and the sun — on Jan. 10, 2026. Typically, an outer planet is at its best for a couple of weeks either side of its opposition; any small telescope should allow a glimpse of its cloud bands, with a 6-inch telescope able to see its Great Red Spot (when it’s facing Earth).

Get out of the house as soon as it gets dark on Boxing Day for one of the most beautiful sights of the week, a crescent moon and the planet Saturn. Now a 41%-illuminated waxing crescent, the moon will appear to curl around the sixth planet, and the two will be separated by a mere four degrees. That’s a bit less than the width of your three middle fingers held at arm’s length against the sky. Saturn will appear as a steady, golden point of light, though you’ll need a small telescope to glimpse its ring pattern.

It’s half-day, half-night on the moon tonight as it reaches its first quarter phase in the southern sky. For amateur astronomers, it’s a bittersweet moment — the next week will see the moon grow in brightness as it waxes towards full, making faint star clusters, galaxies and nebulae harder to see. However, a “half-moon” is one of the best times to explore the lunar surface if you have a pair of binoculars. The line between light and dark — the terminator — cuts right down the middle tonight, causing long shadows to stretch across the lunar plains, making every bump and ridge stand out like a black-and-white relief map. The dark regions you see on the right-hand side of the moon are called maria, Latin for seas, but these are no oceans. These are vast plains of lava that solidified billions of years ago in the aftermath of asteroids slamming into the young moon.

Orion’s Belt — the famous trio of stars in Orion, sometimes nicknamed the “Belt of Orion” or the “Three Kings” — is an icon of the late-December night sky. Look east tonight for Alnitak, Alnilam and Mintaka, strung out in a neat row, rising into the eastern sky as soon as it gets dark. Put a pair of binoculars on them, and you’ll discover great riches. Just to the right is, of course, the Great Nebula in Orion (also called M42). Lesser known is a delicate chain of faint stars curving across the field of view in a subtle “S” shape, running from just above Mintaka to just below Alnilam. It’s very clear through binoculars.

Jupiter getting close to its opposition means more than it merely becoming brighter. Since it’s closest to Earth (about four Earth-sun distances), its disk is bigger in the sky, and it’s visible all night. Jupiter’s opposition is also the best time to see its largest four moons — Io, Callisto, Ganymede and Europa. These moons, called Galilean moons because they were first spotted by Italian astronomer Galileo Galilei in 1610, can be seen in any small telescope as pinpricks of light, but also in binoculars.

As your final stargazing act of the year, step outside as it gets dark and find Orion’s Belt, that iconic trio of bright stars, rising from the eastern horizon like an arrow. Trace Orion’s Belt upward, and high above it, you’ll find the moon, now 92% illuminated. Just above the moon will be the Pleiades — also known as the Seven Sisters and M45 — one of the closest open clusters of stars to the solar system. The bright moonlight may make it hard to see the Pleiades with the naked eye, but any pair of binoculars should bring them into view.
