Eta Aquarid Meteor Shower Peaks Tonight, Moon May Obscure View

Key facts

• The Eta Aquarid meteor shower peaks overnight on May 5-6, 2026.
• The shower is active from April 19 to May 28, 2026.
• Halley's Comet debris fuels the Eta Aquarids.
• Up to 50 meteors per hour may be visible in the southern hemisphere tropics under ideal conditions.
• Northern hemisphere viewers may see 10-30 meteors per hour, but moonlight could reduce that to under 10.
• The waning gibbous moon will be 84% illuminated during the peak.
• The radiant is in the constellation Aquarius, rising above the eastern horizon after midnight.
• Best viewing is in the predawn hours of May 6.

A Celestial Display Dimmed by Moonlight

The Eta Aquarid meteor shower, one of the year's most anticipated celestial events, reaches its peak tonight, offering skywatchers a chance to witness fragments of Halley's Comet burning up in Earth's atmosphere. However, viewing conditions in the northern hemisphere are far from ideal, as a bright waning gibbous moon will compete with the meteors, potentially reducing the visible count to fewer than 10 per hour. The shower, which runs from April 19 to May 28, 2026, peaks overnight on May 5-6. The best time to look is during the predawn hours of May 6, when the shower's radiant—the point in the sky from which the meteors appear to originate—reaches its highest altitude for northern hemisphere observers. For those in the southern hemisphere tropics, the show promises to be more spectacular, with up to 50 meteors per hour possible under clear, dark skies.

Halley's Comet: The Source of the Shooting Stars

The Eta Aquarid meteor shower is a direct result of Earth passing through the debris trail left by Halley's Comet, which orbits the sun every 75-76 years. As the comet sheds dust and ice, these particles become trapped in Earth's path, creating the annual meteor shower. The comet itself was last visible from Earth in 1986 and will not return until 2061, but its legacy continues in the form of these shooting stars. Each meteor is a tiny fragment of the comet, traveling at high speed—about 66 kilometers per second—and burning up as it enters Earth's atmosphere. The resulting streaks of light are often accompanied by persistent glowing trains that can linger for several seconds, adding to the spectacle.

How to Maximize Your Chances of Seeing Meteors

To spot Eta Aquarid meteors, viewers should first locate the constellation Aquarius, which rises above the eastern horizon to the left of the waning moon roughly three hours after midnight for those in the United States. Using a smartphone astronomy app like Stellarium or SkySafari 7 Pro can help pinpoint the radiant amid the moon's glare. Once the radiant is identified, experts recommend looking at a patch of sky about 40 degrees away—approximately the width of four clenched fists held at arm's length. Meteors appearing farther from the radiant tend to have longer, more dramatic trails. The best viewing conditions are away from city lights, with a clear, unobstructed horizon. No special equipment is needed; the naked eye is sufficient.

The Moon's Interference and What It Means for Observers

The waning gibbous moon, 84% illuminated, will rise above the southeastern horizon shortly after midnight on the night of May 5-6, flooding the sky with moonlight. This will wash out fainter meteors, significantly reducing the hourly rate for northern hemisphere viewers. under ideal conditions, northern observers might see 10-30 meteors per hour, but the moon's presence could push that number below 10. For those in the southern hemisphere, the moon will be lower in the sky, and the radiant is higher, offering better viewing conditions. The tropics are particularly favored, with potential rates of up to 50 meteors per hour. Skywatchers in the northern hemisphere are advised to seek out dark locations and consider observing before moonrise to catch the brightest meteors.

Photographing the Meteors: Tips and Gear

Capturing the Eta Aquarids on camera requires some preparation. The Canon EOS R7 is recommended as a good camera for beginners in astrophotography, but any camera with manual settings and a fast lens can work. A tripod is essential to keep the camera steady during long exposures. Photographers should set their camera to a wide aperture (f/2.8 or lower), a high ISO (1600-3200), and a shutter speed of 15-30 seconds. Pointing the camera toward the radiant or slightly away can yield dramatic shots.

What Lies Ahead: Future Meteor Showers and Halley's Legacy

The Eta Aquarids are one of two meteor showers associated with Halley's Comet; the other is the Orionids, which peak in October. While the comet itself will not return until 2061, its debris continues to provide annual displays. For those who miss tonight's peak, the shower will remain active until May 28, though rates will decline sharply after the peak. Looking ahead, the next major meteor shower is the Perseids in August, which typically offer higher rates and better viewing conditions in the northern hemisphere. For now, the Eta Aquarids offer a reminder of the cosmic debris that Earth encounters each year, a celestial dance that connects us to the distant past of our solar system.

The bottom line

• The Eta Aquarid meteor shower peaks overnight on May 5-6, 2026, with best viewing before dawn on May 6.
• Halley's Comet is the source of the meteor shower, with debris entering Earth's atmosphere at high speed.
• A waning gibbous moon (84% illuminated) will hinder viewing in the northern hemisphere, reducing visible meteors to under 10 per hour.
• Southern hemisphere tropics may see up to 50 meteors per hour under ideal conditions.
• The radiant is in Aquarius; look 40 degrees away for the longest meteor trails.
• No special equipment is needed; a dark sky and patience are the best tools.
