A space rock travelling at over 30 kilometres per second turned the evening sky over eastern Australia into a natural light show – and scientists are still tracking where it landed.
At around 6:30pm on Wednesday evening, a meteor exploded with a bright flash that was widely seen across eastern Australia, with stunned onlookers from Sydney to Canberra reporting vivid streaks of colour ranging from blue to green to orange lighting up the night sky.
The fireball was visible from the South Coast, Dubbo, Bathurst, and central New South Wales, with witnesses describing a sudden green-to-orange flash that briefly illuminated the entire sky.
Dashcam footage captured its fiery descent, and social media quickly filled with videos and photographs from across the region, many shot by drivers who pulled over to watch the display.
The event even gatecrashed a sporting fixture. The meteor streaked across the sky over the Australia Cup Qualifier between Queanbeyan City and Canberra Croatia right at kick-off time in Canberra – a piece of timing that ensured a particularly large number of people had their eyes on the sky at exactly the right moment.
What Was It, Exactly?
In technical terms, the fireball was a “bolide” – a category of meteor that is not only brighter than the planet Venus, but which can also be seen to explode or break up as it enters the atmosphere. They are rare to see.
The object was moving very fast, likely in excess of 30 kilometres per second – ruling out space junk, which typically enters Earth’s atmosphere at much slower speeds of roughly 8 kilometres per second.
Astrophysicist Brad Tucker, who witnessed the event from Canberra, was quick to explain what the colours revealed about the object’s composition.
“The greenish colour indicates it was a meteor, usually with iron and nickel,” Tucker told 9 News. “The bright flash midway means it likely fragmented or broke apart.”
On the question of size, Tucker offered two slightly different estimates as analysis continued. He estimated the meteor was about 12 to 20 inches in diameter based on its brightness, while separately putting the object at 30 to 50 centimetres and calling it “a good-sized one,” adding: “May not seem big, but they are super dense so it put on quite the show.”
Where Did It Go?
As of Thursday evening, the exact fate of the object remained unconfirmed. By 8pm, the suspected meteorite had not been officially confirmed, and it was still unclear where it had landed or precisely how fast it was moving. The Desert Fireball Network was working to determine the nature of the object.
Tucker noted that the rock may have broken apart in the upper atmosphere or fallen into the ocean off the New South Wales coast – an outcome that would make physical recovery essentially impossible.
Tucker said he is trying to extend the Desert Fireball Network out to the east coast to better track events of this kind in future.
The network currently operates primarily across Australia’s interior, and events over densely populated coastal areas like Sydney have historically been harder to triangulate precisely.
How Rare Is This?
Rarer than a shooting star, but more common than most people assume. Tucker estimated that something of this size flies over Australia roughly every few weeks – but most shooting stars are tiny specks of dust about the size of a grain of sand. A bolide visible across hundreds of kilometres is a different proposition entirely.
Astrophysicists say the meteor’s size and green hue suggest iron and nickel content, and note that such large events occur roughly monthly across Australia as a whole – though the chances of one occurring over a major city at peak evening hours, and being filmed from dozens of angles simultaneously, are considerably lower.
The event has also drawn attention to the broader importance of public meteor sightings for science. Globally, scientists are improving meteor detection, with AI tools now classifying meteors by measurable traits to assess risks to satellites and people.
Networks like the Desert Fireball Network aim to map meteor paths, while other efforts focus on tracking larger near-Earth objects – a field that has gained significant funding and political attention in recent years following several high-profile near-miss asteroid events.
For most of the witnesses who happened to look up at 6:30pm on Wednesday evening, however, the science was secondary.
What they saw was a streak of blue, green, and orange fire crossing the Sydney sky and disappearing into the dark – a reminder, in the middle of an ordinary Thursday evening, that the solar system occasionally has something to say.
