Summer skies are about to host a dazzling show. The Perseid meteor shower, often called the most popular of the year, will soon reach its peak. Stargazers could see up to 100 meteors every hour, including spectacular fireballs lighting up the night.
Why the Perseids Light Up the Sky
The Perseids appear each year when Earth crosses a trail of dust left by comet 109P/Swift-Tuttle. The comet takes 133 years to orbit the Sun and last passed near Earth in 1992. The meteors, no larger than sand grains, slam into our atmosphere at over 215,000 kilometres per hour. The heat from friction turns them into glowing streaks. Larger particles create fireballs that burn brighter and longer than regular meteors.
When and Where to Watch the Perseids
The shower began on 17 July and will last until 24 August. Its peak will fall on the night of 12 August, with the best viewing between midnight and dawn. On 11 and 12 August, Jupiter and Venus will appear close together, adding to the celestial display. Viewers should look towards the constellation Perseus, found below the W-shaped Cassiopeia. Looking slightly away from Perseus often reveals meteors with longer trails.
Moonlight May Dim the Display
This year’s peak coincides with an 84% full moon. The bright moonlight could hide many of the fainter meteors. Astronomers suggest blocking the moon with a building or tree to improve visibility. For the clearest views, escape city lights and find an open, dark location such as the countryside or coast. Experts also recommend allowing eyes to adjust to darkness for at least 10 minutes. Patience, they say, is the key to spotting the year’s most spectacular meteor show before it fades.
