Aussies are no strangers to spectacles by nature.

Earlier today, citizens across the country witnessed a celestial spectacle as a 'giant fireball' blazed through the sky.

The remarkable sighting left a trail of wonder and a flurry of phone calls to local radio stations as people wanted to understand what they just witnessed.

Sightings of the 'giant fireball' were reported from various locations, including Sydney, Penrith, Richmond, the Hunter Valley, and even Toowoomba.

The fiery display sparked a wave of calls to 2 GB's Ben Fordham as listeners shared about the sighting and looked for explanations.

Each caller shared their unique perspective of the event, with descriptions ranging from a simple 'shooting star' to a more dramatic 'meteorite or a fireball' that plummeted from the heavens.

Australian National University's Space Expert Brad Tucker hopped in and provided some clarity on the phenomenon.

Tucker confirmed the suspicions of many, as the bright flash was indeed a meteor passing by the Earth's atmosphere.

'It sounds like a meteor based on what everyone is saying due to its fast nature,' Tucker explained to Fordham on the radio show.

'Meteors move across the sky in seconds, if that.'

Several observers also noticed a green tinge on the meteor, to which Tucker also explained why.

'These meteors, which are broken-off asteroids, burn a greenish-blue colour due to the iron-nickel in them,' he said.

This particular meteor was visible across vast stretches of Australia, thanks to its high altitude and the clear morning sky.

'It clearly covered a lot of distance in a short amount of time, so definitely a broken chunk of an asteroid that randomly hit the earth's atmosphere,' Tucker elaborated.

What exactly is a meteor, and why does it create such a stunning visual effect?

Asteroids, the parent bodies of these meteors, travel at incredible speeds ranging from 50,000 to 100,000 kilometres per hour.

A meteor is a streak of light in the sky produced by a small piece of an asteroid or comet called a meteoroid.

Due to its composition, meteors burn up when it enters the Earth's atmosphere.

These rocks also vary in size, and they become meteors or shooting stars once they collide with our atmosphere.

A meteor could be exceptionally bright and outshine other planets—which are then classified as a 'fireball'.

Though awe-inspiring, these events are relatively common.

National Aeronautics and Space Administration (NASA) reported that around 44,000 kilograms of meteoritic material falls on Earth every day.

The 'giant fireball' that enthralled Aussies is a reminder of the dynamic and ever-changing nature of our universe.

It's a phenomenon that connects us with the cosmos, offering a glimpse into the vastness of space and the wonders it holds.

Key Takeaways

• Hundreds of Australians witnessed a 'giant fireball' in the sky, identified as a meteor passing over the country.
• The spectacular event generated calls to a radio station as people sought to understand what they had seen.
• Space expert Brad Tucker confirmed it was a meteor, with its bright flash and green tinge indicating it's a chunk of asteroid entering the Earth's atmosphere.
• Meteors, sometimes referred to as shooting stars or fireballs, are caused by meteoroids burning up upon entering the Earth's atmosphere at high speed.
