Eta Aquarid Meteor Shower to Peak Amid Bright Moonlight

The Eta Aquarid meteor shower, composed of debris from Halley's Comet, is set to peak on the night of May 5 into the early hours of May 6, 2026. This annual event typically offers a display of meteors, especially in the Southern Hemisphere, where observers can see up to 50 meteors per hour under optimal conditions. However, this year's viewing may be hindered by a bright waning gibbous moon, which will be 84% full during the peak. The moonlight is expected to reduce visibility, potentially cutting the number of visible meteors by half in the Southern Hemisphere. In the Northern Hemisphere, where the radiant point of the shower is lower in the sky, viewers might see fewer than 10 meteors per hour.

Meteor showers occur when Earth passes through trails of debris left by comets or asteroids. These particles collide with Earth's atmosphere at high speeds, producing streaks of light known as shooting stars. The Eta Aquarids are associated with Halley's Comet, which orbits the Sun approximately every 76 years and is next expected to pass by Earth in 2061.

For the best viewing experience, it's advisable to go outside just before dawn, away from city lights and tall buildings, to get a clear view of the sky. Positioning oneself to block the bright moonlight can also improve visibility. Observers should look toward the east, near the constellation Aquarius and the bright star Eta Aquarii. Allowing time for eyes to adjust to the darkness and avoiding looking at phone screens can enhance the experience.

Despite the challenges posed by moonlight, witnessing a meteor shower firsthand remains a unique experience. As Teri Gee, manager of the Barlow Planetarium in Wisconsin, noted, "It almost feels like you're discovering it yourself."
