The mystery of the loud bang that woke up parts of the North-West Coast in the early hours of Saturday morning could have an out-of-this-world explanation.
Short video footage shared to a Facebook post asking whether anyone had heard an explosion around 2am, showed a slight change in the angle of light.
Principal astronomer at Hive Martin George wasn't in the region that morning, but he said the change in light shown in that vision was consistent with meteor activity overhead.
"From what I've seen I'm almost certain it was a meteor activity," Dr George said.
"It was obviously very bright... It's unfortunate people weren't outside to see it."
Dr George said it was his opinion that it did sound like it was a sonic boom or an exploding meteoroid.
He said that had there been uniform cloud cover it would be possible people wouldn't have seen it occur.

A sonic boom, Dr George said was caused when a physical object moved faster than the speed of sound in the air, likening it to the noise made by Concorde planes.
He said an airburst was caused by an object breaking up in the atmosphere.
"An airburst has been known to cause windows to rattle."
If it was meteoroid activity, Dr George said the size of the meteoroid would have been maybe a little larger than a cricket ball.
"It's very hard to estimate the size of the object."
On Saturday afternoon, a post on Facebook asked whether anyone had heard an explosion at 2am.
People from Waratah, Wynyard, Burnie and Somerset replied to the post, citing a bright flash and several cracked windows.
Waratah resident Val Flemming said her window was left cracked after hearing and waking up to rumbling, shaking windows and a loud sound.
"It was clear it wasn't thunder, I know what thunder sounds like," she said.
"I've never heard anything like it in my life."
Tasmania Police said there was one report of a loud bang from Wynyard about 2am.
"Burnie units didn't locate anything," the Tasmania Police spokesman said.
