May 2026 Skywatching Guide: Meteors, Planets, and a Blue Moon

Welcome to May 2026, a month packed with celestial wonders for skywatchers. From the swift streaks of the Eta Aquarid meteor shower to a dazzling meetup between the Moon and Venus, and concluding with a rare Blue Moon, there’s something for everyone. Here are the top events and how to observe them.

What is the Eta Aquarid meteor shower and when does it peak?

The Eta Aquarid meteor shower is an annual event that peaks around May 5th and 6th. These fast-moving meteors, traveling at about 40 miles per second, can produce up to 50 meteors per hour under ideal dark skies. They often leave behind glowing trails that linger for a moment after the flash. For the best view, watch in the hours before dawn, looking generally eastward. However, bright moonlight this year may wash out some fainter meteors.

Where do Eta Aquarid meteors come from?

These shooting stars originate from Halley's Comet. Every year, Earth passes through the comet's dusty trail, and tiny particles burn up in our atmosphere, creating bright streaks. Halley's Comet last visited the inner solar system in 1986 and won't return until 2061. The shower appears to radiate from the constellation Aquarius, which gives it its name.

What is the Moon-Venus conjunction on May 18?

On the evening of May 18, look west just after sunset to see a stunning pairing: the crescent Moon and brilliant Venus shining close together. Venus, often called the Evening Star, is one of the brightest objects in the sky. From Earth, they appear near each other due to alignment, but in reality they are millions of miles apart. This is an easy target to spot with the naked eye.

What is a Blue Moon and when does it happen in May?

A Blue Moon is the term for the second Full Moon in a single calendar month. It’s a relatively rare event, hence the phrase “once in a blue moon.” In May 2026, the Full Moon occurs on May 31st, making it a Blue Moon. Despite the name, the Moon won’t actually appear blue; it’s just a quirk of the calendar.

What are the best tips for viewing these sky events?

For meteor showers, find a dark location away from city lights. Give your eyes about 20 to 30 minutes to adjust to the darkness, and avoid looking at bright screens like your phone. For the Moon-Venus conjunction, a clear western horizon after sunset is all you need. Remember, patience and comfort (like a reclining chair) can enhance your experience.

Are there any other notable sky events in May 2026?

While not occurring in May, it’s worth noting that last month (April 2026) saw the launch of Artemis II around the time of the April 1st Full Moon, sending astronauts around the Moon for the first time in over 50 years. This mission provided spectacular new views of our nearest neighbor and sets the stage for future lunar exploration.
