A meteor burned alien green and caused a “huge explosion” after racing through the sky above Turkey.

The celestial event shocked onlookers, with many speculating it could be a falling satellite or an out-of-control UFO.

Otherworldly scenes above the Aegean coastal city of Izimir were captured on video at 2am yesterday.

In some clips the green object disappeared behind hills but other footage shows a bright glow before the meteor appears to crash to earth.

The extraordinary incident prompted many to speculate as to exactly what it could be.

One person wrote: “UFOs have been seen in the sky #PrayforTurkey.”

Another added: “Strange, bright object believed to be a rocket debris crashed in Turkey. Satellite?”

But Dr Hasan Ali Dal’s explanation, while less exciting, did put people’s minds at rest, reports The Sun.

The astrophysics professor told his followers that the “fireball” phenomenon occurs when a meteor begins to burn up as it enters the Earth’s atmosphere.

Space rocks will often disintegrate before reaching the ground but if they do crash into Earth they are classed as meteorites.

Sometimes the process of disintegration can sound like an explosion.

“It usually burns away in the upper atmosphere,” said the professor, adding “It should be considered as a more specific version of the phenomenon known as a shooting star among the people and it often experienced during periods of meteorite rains.”

The Perseid Meteor Shower which happens every year through July an August sees up to 50 meteors an hour shoot through the sky at 133,200mph, with the vast majority never reaching Earth.

The shower occurs when Earth crosses paths with debris left behind from Comet Swift-Tuttle.

It’s likely the alien glow surrounding the Izimir object was down to the amount of nickel in the rock.

About 90% of meteors contain no metal but some are made wholly or partly of iron and nickel.

The sighting came as the region of Turkey battles more than 100 fierce forest fires.
