A video caught the moment the skies lit up a bright green as a meteor crashed to Earth. You can check it out here: A Twitter user in the city of Izmir in Turkey shared the incredible footage which appeared to show the sky lighting up a brilliant green before the object hurtled towards the ground. The videos have sparked speculation surrounding just what the object could be, with some suggesting it's a satellite or some intergalactic junk and others choosing to believe it could be aliens. Fingers crossed for the aliens, eh? I reckon that's just what 2021 needs, to be honest.

Posting on Twitter one resident said: "Strange, bright object believed to be a rocket debris crashed in Turkey. Satellite?"While another wrote: "UFOs have been seen in the sky."However, before you grab your tinfoil hat, astrophysics professor Dr. Hasan Ali Dal shared his expert - if not wholly less exciting - opinion. Posting on Twitter he said the bright colours were caused by a 'fireball', which happens when a meteor begins to burn up as it enters the planet's atmosphere.

The annual event occurs when the Earth passes through an area filled with debris from the Comet Swift-Tuttle. The Perseid Meteor Shower.

If you fancy catching a glimpse of one, earthsky.com reckons the best days are 11, 12 and 13 August. To give yourself the absolute best chance of seeing one, head to a place with minimal light pollution before dawn.
