Orionid meteor shower peaks tomorrow across Australia—here's how to catch it

The Orionid meteor shower arrives this week, and if you find a dark patch of sky and look north-east after midnight, you might catch one of nature's quieter spectacles. The shower peaks on the early morning of October 22, when Earth passes through the densest part of a debris trail left by Halley's Comet as it travels through space. In ideal conditions—dark skies, clear weather, patience—observers in northern Australia could see as many as 20 meteors streak across the sky each hour. Those in the south might see closer to a dozen. The timing is fortunate: this year the peak coincides with a new moon, meaning less lunar glare to wash out the fainter trails.

The Orionids are not new. They happen every October as Earth's orbit intersects with the dust and gas Halley's Comet sheds on its long journey around the sun. The shower has already begun and will continue through November 7, but the window for the best display is narrow. The radiant point—the spot in the sky from which the meteors appear to originate—rises around midnight but climbs higher as the night deepens. Jonti Horner, an astronomer at the University of Southern Queensland, suggests waiting until around 4 or 5 in the morning if you have daylight savings time, when the radiant point reaches its highest arc above the horizon. From there, it remains visible until close to sunrise across all of Australia.

Finding the radiant point requires a bit of stargazing literacy but nothing more. Head outside to somewhere genuinely dark—away from streetlights and house lamps—and look north-east. Give your eyes time to adjust; this takes several minutes and demands that you leave your phone in your pocket. Once the darkness settles into your vision, locate Orion's belt, sometimes called the saucepan. Below it sits Betelgeuse, one of the brightest stars in the night sky and Orion's shoulder star. The radiant point sits just beneath Betelgeuse. From there, you wait.

This is where patience becomes the real requirement. Horner notes that although the average might be around 10 meteors per hour, they do not arrive in any predictable rhythm. You might wait 25 minutes without seeing anything, then watch two or three meteors flash across the sky within minutes of each other. It is not one every six minutes. The variability is part of the experience—the reason to bring a blanket, settle into the grass, and let the sky reveal itself on its own schedule.

The meteors themselves are tiny: specks of dust and debris no larger than grains of sand, burning up as they enter Earth's atmosphere at high speed. What makes the Orionids distinctive is their source. This same debris trail crosses Earth's path again in May, producing the Eta Aquariid meteor shower. Most meteor showers result from Earth moving through the remnants of comets, though one—the Geminids in December—originates from an asteroid called 3200 Phaethon. Horner describes the Geminids as the best shower of the year, worth marking on the calendar if the Orionids slip past unnoticed.

The practical reality of viewing depends heavily on where you are and what the weather does. Northern Australia has the advantage of a higher radiant point, offering better odds of seeing the full count. Southern observers will see fewer meteors simply because the radiant point sits lower on the horizon. Cloud cover, of course, erases everything. Many websites publish inflated estimates of what you might see, but those numbers assume perfect conditions that rarely exist outside a planetarium. The actual experience—the number of meteors you will witness—depends on your location, the darkness around you, and the sky's cooperation. What remains constant is the invitation: find somewhere dark, look up, and see what appears.
