BRIT stargazers will have a golden opportunity to watch the Perseid meteor shower tonight.

The spectacular annual display which lights up the night sky is predicted to reach its peak overnight tonight, August 12, with around 100 shooting stars an hour.

Just how much of a spectacle is actually seen will largely be down to the weather conditions in your area and the amount of light.

Senior astronomer at the Royal Observatory Greenwich, Dr Ed Bloomer said: "The Perseids should give good viewing a couple of days either side, with local weather and light conditions probably more significant factors than the precise mathematical peak."

Experts believe the meteors come from between the constellations of Camelopardalis and Persus, from which their name is derived.

It is best to look at them out of the corner of your eye, according to Bloomer.

He said: "Perseus is rising in the north-east as the sun's going down, and so you want to look maybe more over towards the east."

Dr Bloomer added that peripheral vision is more sensitive under low-light conditions than central vision

The Perseid meteor shower happens when the Earth hits material shed from the comet 109P/Swift-Tuttle as the planet orbits around the Sun and is best seen in the northern hemisphere.

When fragments, usually no bigger than a grain of sand, reach Earth's atmosphere the air in front of the particles becomes compressed, producing heat and causing the fragments to burn up.

That results in bright, colourful, streaks across the sky.

Dr Bloomer said: "[The comet] is on this big, long 133-year orbit around the Sun, and it's essentially debris that's trailing off from behind that - so Swift-Tuttle makes its orbit, but the Earth then essentially crashes into that path year after year."

Anyone wanting to catch a glimpse of the celestial show is advised to go out at night and head to a dark area, away from street lighting and they should also avoid looking at their phones.

Ideally, people should lay on the grass where you can get a clear view of the whole night sky and look upwards.

Give your eyes around 30 minutes to adjust to the darkness.

Anyone who is particularly keen on getting the best display, they can download a stargazing app, find the Perseus constellation and look in that direction.

Dr Bloomer said: "You might get lucky and see a fireball, [that's] a bit of debris about the size of your fist coming through the atmosphere - that can go [on] for five, 10 seconds.

"You might even see it break up, and that's pretty special.

"But the majority of these things are little flashes."

He added: "It's not fireworks.

"But you're sort of seeing the mechanics of the solar system at work, which is quite an interesting thing."
