Mysterious green flash lights up night sky

Aussies have been left stunned after an “out of this world” sight lit up the sky early on Mother’s Day.

Early risers from Perth to the Goldfields have had the celestial show of a lifetime after a mysterious green light lit up the sky just before 6am yesterday.

Experts from the Perth Observatory were able to capture the light through surveillance cameras and believe it was most likely a “small meteor”.

In a clip shared to social media a Kalgoorlie man captured the incredible sight while out prospecting in the outback.

As he pans his camera around the bushland he can be heard saying, “It’s Mother’s Day, we’ve got to start coming out here a bit later because it’s 6am and it’s dark.”

Out of nowhere, he excitedly shouts “Look, look, meteor” as a bright light burns through the sky.

“What a sight, wow,” he exclaims as the meteor leaves a spectacular green trail behind it.

Matthew Woods from Perth Observatory told the ABC that it may have entered the atmosphere over the central wheatbelt but they’re not entirely sure where it landed.

“It’s most likely an iron meteor that’s been orbiting within the inner solar system.”

Mr Woods said the meteor would have heated up because of the friction caused when it came through the atmosphere.

“And that’s where you’re getting to see that lovely green, orange glow,” he said.

He estimates the meteor to be anywhere between the size of a cricket ball to the size of a basketball.

Stunned witnesses took to social media to report seeing a “fireball” tear through the sky.

“I’ve never seen anything like it,” said one truck driver.

“I saw it in Mandurah looking east. A very vibrant green tail with an orange fireball which appeared to explode,” said one woman.

“I saw it from Mt Magnet WA at about 6am. It was so big and bright that I initially thought that it was the moon until it moved,” wrote another.

Mr Woods said witnessing a fireball in the sky was rare because the Earth was 70 per cent ocean.

“Earth gets hit by about 100 tonnes of material each year, so most of these really bright ones happen over the ocean or while we sleep.”

Experts are still looking to locate the site where it landed but said overall the event was “a nice Mother’s Day surprise.”
