The annual Perseid meteor shower reaches its peak this weekend, with NASA and the Royal Astronomical Society advising Northern Hemisphere skywatchers on optimal viewing conditions. The Perseids rank among the year's most reliable meteor displays.

Earth passes through debris left by comet Swift-Tuttle each August, producing the shower. Under dark skies, observers can see 50 to 100 meteors per hour near peak, according to NASA's Meteoroid Environment Office. The radiant lies in the constellation Perseus, which rises in the northeast after midnight.

A bright waning moon will wash out fainter streaks and reduce visible rates this year. The American Meteor Society recommends viewing in the pre-dawn hours, away from city lights, and looking toward darker regions of the sky rather than directly at the radiant.

Public observatories and astronomy societies across the United States, United Kingdom and Europe have organised viewing events and livestreams for the weekend. The Perseids remain a popular entry point for amateur astronomy, requiring only the naked eye and clear, dark conditions.

The shower typically peaks around August 12 and 13. Meteor activity will build steadily through the coming nights, giving observers multiple opportunities before the maximum.
