Get ready for the best light show of the year – the Perseid Meteor Shower is coming soon to a night sky near you! In 2018, peak activity occurs in the night of 12-13 August.

Every year in August, the Earth crosses the orbital path of Comet Swift-Tuttle. Comets constantly shed dust and stones as they fly around the Sun, and it is this debris along Swift-Tuttle’s path that causes the Perseids. The debris hits Earth’s atmosphere at more than 200,000 kilometres an hour and burns up in bright, short blazes about 80 kilometres off the ground.

Comet Swift-Tuttle takes 133 years to orbit the Sun and has been shedding debris for thousands of years. The first record of the Perseids dates back to 36 AD in ancient Chinese annals.

The comet itself last approached Earth in 1992 and will next be visible from Earth in 2126. When this happens it will be a bright comet easily visible with the naked eye, but that will be for future generations to enjoy.

How to watch the Perseids

The Perseids are named after the summer constellation Perseus as this is the direction from which they appear to originate. While the meteors originate from this point they can be best seen 30 degrees away from Perseus, stretching across large sections of the sky.

To view the Perseids from the UK, head out in the late evenings of 11, 12, 13 August, on whichever night is the most clear.

In 2018, the thin crescent moon will set by 21:30, leaving dark skies for an excellent show.

The best viewing will be from a dark location after midnight.

You do not need to look in any particular direction. Lean back, let your eyes adjust to the dark, and watch the whole sky (it helps to have friends look in different directions).

The darker the location the better, so find the darkest sky you can away from city lights.

As always in the UK, clouds can be an issue, but be patient. The Perseids can be so frequent (2-3 meteors a minute) that a quick break in the clouds can be enough to reveal several bright meteors.

You can look for the Perseids on other nights as well. The shower runs annually between 17 July and 24 August 2018.

While you’re stargazing, be sure to also check out the planets Mars and Saturn.

Mars will be visible as a bright, faintly red point of light in the southern sky from about 22:00-01:30 local time.

Saturn will be in the southern sky during the evening sky, from about 21:00-00:00 local time. Through good binoculars or a small telescope, it’s possible to see the distinct rings of Saturn.
