Tonight’s sky has a special treat for South African stargazers

South Africans stargazers have a good reason to step outside this Monday evening, 14 September.

A striking celestial pairing will be visible shortly after sunset, with two of the brightest objects in the sky appearing remarkably close together.

The event should be visible without any special equipment, although having a clear view of the horizon will make all the difference.

What stargazers will see

The two objects involved are the Moon and Venus.

Tonight, the young crescent Moon will appear close to brilliant Venus in the western evening sky.

Venus is currently particularly bright, making it relatively easy to spot even for casual stargazers. The thin crescent Moon should make the pairing even more noticeable.

The two aren’t actually close together in space. They simply appear close from our perspective on Earth as they line up in the sky.

This is known as a conjunction, or apparent close approach.

When should you look?

The best opportunity will be shortly after sunset this evening.

Look towards the western to west-southwestern sky, where the pair will appear relatively low above the horizon.

Because they will be low in the sky, timing is important. Waiting too long could mean both objects have moved closer to the horizon and become harder to see.

A location with an unobstructed view, such as an open beach, hilltop or field, will give you the best chance.

And you won’t need a telescope. The Moon and Venus should both be visible to the naked eye, assuming skies are clear.

Why is tonight’s event particularly interesting?

There’s actually more to today’s Moon-Venus encounter than meets the eye.

Earlier on 14 September, the Moon will pass directly in front of Venus from certain parts of the world.

This is known as a lunar occultation.

During an occultation, the Moon temporarily blocks another celestial object from an observer’s view. In this case, Venus disappears behind the Moon before emerging again.

The exact visibility and timing of the occultation depends on where you are on Earth, and much of the event occurs during daylight for some locations.

For most South Africans, therefore, the evening pairing is the much easier event to enjoy.

There’s more to see later this month

Tonight’s pairing is also a preview of what is shaping up to be a good month for Venus watchers.

The planet will remain prominent in the evening sky during September and is expected to reach its greatest brightness of 2026 on 22 September.

So even if clouds ruin tonight’s show, there will still be plenty of reasons to keep looking up.

But for those with clear skies tonight, the instructions are wonderfully simple: Wait for sunset, face west and look up.
