May 2026 Sky Watching Guide: Meteor Showers, Planets and Two Full Moons
May 2026 is a spectacular month to look up. Whether you are a seasoned astronomer or someone who just wants to step outside with a blanket and a sense of wonder, this month delivers a rich calendar of celestial events. From the dazzling Eta Aquarid meteor shower to a rare Blue Moon at month's end, here is everything you need to know, date by date.
May 1 - The Flower Moon
May opens with the first of two full moons this month, a rare treat in itself. Known as the Flower Moon (also called the Milk Moon or Hare Moon by various Indigenous traditions), this full moon rises just after sunset and offers gorgeous photo opportunities as it clears the horizon in a warm amber hue.
This is a perfect night to bring the family outside. The full moon is bright enough to explore by eye and binoculars, and its reflection off calm water or open fields is simply breathtaking. If you love the Moon as much as we do, take a look at our Earth's Moon Poster, a stunning piece of wall art that captures both sides of our nearest celestial neighbor in exquisite vintage detail.
Tip: A full moon is bright, which is great for families, but not ideal for deep-sky observing. Save your dark-sky sessions for the new moon window later in the month.
May 5-6 - Eta Aquarid Meteor Shower Peak
This is the headline event of May 2026: the Eta Aquarid meteor shower peaks on the morning of May 5-6. What makes it extraordinary? These shooting stars are actual debris from Halley's Comet, the most famous comet in history, last seen from Earth in 1986 and not returning until 2061. Every May, Earth passes through the dusty trail it left behind, and those tiny particles burn up in our atmosphere at roughly 40 miles per second, creating fast, brilliant streaks across the sky, often with glowing trains that linger for seconds after the flash.
According to NASA, under ideal conditions the Eta Aquarids can produce up to 50-60 meteors per hour. In 2026, a waning gibbous moon (about 81-83% illuminated) will wash out some of the fainter meteors, but the brightest fireballs will still punch through. NASA meteor expert Bill Cooke recommends heading outside around 2:00 a.m. local time and watching until dawn, facing east and keeping the moon behind a hill or tree if possible.
- Peak: Predawn hours of May 6 (also good May 4-5)
- Best from: Southern Hemisphere or tropics; Northern Hemisphere can expect roughly 10-20 meteors per hour
- Best time: 2:00 a.m. to dawn, local time
- Equipment: None required; just dark skies and your eyes
- Moon interference: High; try to block it from view with a tree or building
- Special feature: These meteors leave glowing persistent trains that can linger for seconds to minutes
- Duration: Active from April 15 to May 27; even off-peak nights can yield meteors

May 18-20 - Venus, Jupiter, the Moon and M35 in Gemini
On the evenings of May 18-20, the night sky delivers one of its most photogenic moments of the year. Look west just after sunset and you will find a thin crescent Moon joining dazzling Venus (the brilliant Evening Star) and mighty Jupiter in the constellation Gemini. All three are completely naked-eye visible, no equipment needed.
On May 20 in particular, Venus also sits near the open star cluster M35, making this patch of sky especially rich and rewarding through binoculars. This kind of multi-object grouping is rare, memorable, and universally accessible, making it a perfect family stargazing night.
Photography tip: The crescent Moon, Venus, and Jupiter triangle makes for a stunning wide-angle shot. Set up just after sunset, face west-southwest, and shoot at ISO 1600 for 1-3 seconds with a 24-35mm lens. Works well on a phone too.

May 31 - The Blue Moon (Micro Moon)
May ends the way it began, with a full moon, but this one is special. The Blue Moon on May 31 is the second full moon in a single calendar month, which happens because the Moon's 29.5-day cycle does not divide evenly into our months. This year, 2026 will have 13 full moons in total.
The Moon will not actually appear blue; that is just a fun name rooted in old almanac traditions. But it will be the smallest full moon of 2026, occurring near the Moon's farthest point from Earth (apogee), making it a so-called Micro Moon, the opposite of a Supermoon. Still beautiful. Still worth stepping outside for.
"Once in a Blue Moon" - now you will always know when to say it.

Stargazing Tips for May 2026
- Check the weather: Clear skies are everything. Use a 3-day forecast to plan your session.
- Escape city lights: Driving 30-60 minutes from the city dramatically improves what you can see.
- Dark-adapt your eyes: Stay away from bright lights and phone screens for at least 20 minutes before observing.
- Use a red flashlight: Red light preserves your night vision; white light destroys it instantly.
- Dress warmer than you think: Even in May, lying still outdoors at 2 a.m. gets cold fast. Bring layers.
- Lie flat on your back: For meteor showers, looking straight up takes in the most sky.
- Download a sky app: Sky Tonight, SkySafari, or Stellarium make it easy to identify what you are seeing in real time.
