A police officer who was looking for speeding motorists early Tuesday morning instead captured a meteor lighting up the skies above Maine.

The fireball was seen in much of New England, as far south as New Jersey and as far north as Canada.

A post on the police department's Facebook page said: "You never know what you are going to see on duty.

"Sergeant Farris was looking for speeders while parked in front of the central fire station and was able to observe some visitors 'from away'....far away.

"The meteor (or alien spaceship) was caught on camera at approximately 0050 hours. Let's hope the visitors are friendly."
