Key Patterns to Know

8 essential stars and star groups visible from Brisbane. Click the map above to highlight them.

✦
Southern Cross (Crux)
Best: April to June (Autumn/Winter)
The most important constellation in the Southern Hemisphere. It appears on the Australian flag and is used by navigators to find true South without a compass.
How to find it
Look for 4 bright stars forming a cross or kite shape tilted on its side. The long axis of the cross always points toward the South Celestial Pole. It is never visible from anywhere north of about 25 degrees north latitude.
➤➤
The Pointers (Alpha and Beta Centauri)
Best: April to July (Autumn/Winter)
Two of the brightest stars in the sky. Alpha Centauri is actually the closest star system to our Sun at only 4.37 light years away. Together they point directly to the Southern Cross.
How to find it
Find the Southern Cross, then look to its left for two very bright stars close together. They are noticeably brighter than most stars around them. The line from the Pointers through the Cross leads you to South.
🦂
Scorpius (The Scorpion)
Best: June to August (Winter)
Scorpius is one of the most spectacular constellations in the sky. Its heart is Antares, a red supergiant star so huge that if it replaced the Sun, it would swallow up Mercury, Venus, Earth and Mars. "Antares" literally means "rival of Mars" because of its reddish colour.
How to find it
Look for a distinctive curved line of stars shaped like a scorpion with a curved tail. The bright reddish star near the middle is Antares. In Brisbane's winter, Scorpius rides high in the northern sky, which is actually the southern direction for this constellation.
🏹
Orion (The Hunter)
Best: December to February (Summer)
From Brisbane, Orion appears upside down compared to how Northern Hemisphere people see it. Rigel is a blue supergiant, 860 light years away. Betelgeuse is a red supergiant and one of the largest stars known. It will explode as a supernova sometime in the next 100,000 years!
How to find it
Look for Orion's Belt, three stars in a straight line. From Brisbane, the Belt appears to slope down from right to left. Bright Rigel is at the bottom-left, and reddish Betelgeuse is at the top-right (from our upside-down perspective).
💫
Canopus (Carina)
Visible almost all year from Brisbane
The second brightest star in the entire night sky and only visible from the Southern Hemisphere. It is so reliable that NASA has used Canopus as a navigation reference for spacecraft including the Voyager probes. It is about 310 light years away and 65 times wider than the Sun.
How to find it
Look toward the southern sky for a very bright white star sitting low on the horizon. It is the brightest star in that region of sky. From Brisbane it is circumpolar, meaning it never fully sets below the horizon throughout the year.
⭐
Sirius (Canis Major)
Best: January to March (Summer)
Sirius is THE brightest star in the entire night sky, so bright it can sometimes cast a faint shadow on a dark night. It is "only" 8.6 light years away, making it one of our nearest stellar neighbours. Ancient Egyptians used its rising to predict the annual Nile flood.
How to find it
Sirius is almost impossible to miss. Find Orion's Belt, then follow the belt's line toward the upper right. The extremely bright blue-white star you hit is Sirius. Nothing else in the night sky outshines it.
☁️
Magellanic Clouds (LMC and SMC)
Best: July to September (Winter) away from city lights
These are not clouds at all, they are two entire dwarf galaxies orbiting the Milky Way. The Large Magellanic Cloud is 160,000 light years away and the Small Magellanic Cloud is 200,000 light years away. They are only visible from the Southern Hemisphere and look like detached pieces of the Milky Way.
How to find it
On a clear, dark night away from city lights, look toward the southern sky. You will see two fuzzy whitish patches that look like small clouds that do not move. The Large one is bigger and brighter. They are best seen during winter from a dark rural location.
🌌
The Milky Way Band
Best: June to August (Winter), dark skies needed
What you see is our own galaxy viewed from inside, edge-on. The bright central bulge you can see in winter is the actual centre of the Milky Way galaxy, about 26,000 light years away. Australia has some of the darkest skies in the world, making it one of the best places on Earth to see it.
How to find it
You need to get away from Brisbane's city lights. Drive at least 60 km into the countryside and let your eyes adjust for 20 minutes. Then look for a broad, bright, misty band stretching all the way across the sky from horizon to horizon.

How to Find South 🧭

No compass? No problem. The Southern Cross tells you exactly where South is. Here is how.

1
Find the Southern Cross. Look for 4 bright stars forming a kite or cross shape. Two of the stars are much brighter than the other two.
2
Identify the long axis of the Cross. The two stars at the top and bottom of the kite form this line. The bottom star is called Acrux.
3
Extend the long axis 4.5 times its own length beyond the bottom star (Acrux). This imaginary point is the South Celestial Pole.
4
Tip: use the Pointers to double-check. Draw a line at right angles to the Pointers, halfway along the line between them. This line also leads to the South Celestial Pole.
5
Drop straight down from the South Celestial Pole to the horizon. That point on the horizon is true South!
★
Scout tip: Once you have found South, face it. Your left is East, your right is West, and behind you is North. You now have your compass bearings without any equipment.

Star Facts 🌠

Amazing facts about the stars above Brisbane every night.

🚀
Nearest Star to Us
Proxima Centauri, part of the Alpha Centauri system (The Pointers), is the closest star to our Sun. At the speed of the fastest spacecraft ever launched, it would still take about 73,000 years to reach it.
4.24 light years
🌌
Stars in the Milky Way
Our home galaxy contains somewhere between 200 and 400 billion stars. Scientists cannot count them directly, so they estimate based on the galaxy's mass. You can see around 5,000 of them with the naked eye on a clear night.
200-400 billion stars
✨
Why Stars Twinkle
Stars twinkle because their light passes through many layers of Earth's atmosphere with different temperatures and densities. Each layer bends the light slightly differently, causing the star's apparent position to jitter rapidly. Planets do not twinkle as much because they appear as small discs, not pinpoints.
It's the atmosphere!
🇦🇺
Southern Cross on Our Flag
The Southern Cross appears on the Australian flag because it can only be seen from the Southern Hemisphere, making it a powerful symbol of Australia's unique identity. It was on colonial flags from the 1820s and chosen for the official national flag in 1901.
Since 1901
📏
What is a Light Year?
A light year is the distance light travels in one year. Light travels at about 300,000 km every single second. In one year, light covers about 9.46 trillion kilometres. When you look at a star 100 light years away, you are seeing light that left it 100 years ago.
9.46 trillion km

Canopus Guides Spacecraft
NASA spacecraft use Canopus as a navigational reference star. Because it is so bright and in a reliable position, it acts as a fixed beacon. The Voyager probes launched in 1977, the Mars rovers, and many other missions have all used Canopus to orient themselves in space.
