As May progresses, the night sky keeps changing this week: the bright full moon dims, and a major meteor shower arrives. After sunset, Venus appears in the west while spring constellations shine. Here’s how to make the most of stargazing in the coming days:
The Eta Aquariids, caused by debris from Halley’s Comet, appear when Earth passes through this dust stream each year.

May 5-6The Eta Aquariid meteor shower reaches its peak overnight from May 5 to 6. Best seen before dawn, it typically offers 10-20 fast meteors per hour from mid-northern latitudes, some leaving persistent streaks across the sky. For the best views, look toward the east or southeast in the hours before sunrise. Although some moonlight will be present, brighter meteors should still stand out.
May 9A few nights later, the Moon reaches last quarter on May 9. Rising at midnight, it leaves early evening hours moonlight-free, opening a darker window ideal for spotting fainter stars and constellations.
All weekThe planet Venus continues to rise higher, and shine more brightly, in the post-sunset evening sky. Look west.
The Eta Aquariids, caused by debris from Halley’s Comet, appear when Earth passes through this dust stream each year. Tiny particles striking the atmosphere create meteors, most visible just before dawn when Aquarius rises. While this shower is best in the Southern Hemisphere, observers in the north can still expect 10-20 meteors per hour—about half the southern rate.
Boötes is anchored by Arcturus.

Look for Boötes high in the east after dark. This constellation—anchored by Arcturus—forms a loose kite (or cocktail glass) shape and is one of the easiest spring constellations to learn once you’ve found Arcturus. An ancient depiction of a herdsman, Boötes is memorable for its prominence and bright central star.
On May 12-13, a waning crescent moon will appear low in the east, near Saturn, before sunrise for a brief pre-dawn view. On May 15, a 4%-lit waning crescent passes close to Mars. After the new moon on May 16, look for a young crescent in the west at sunset, near Venus and Jupiter on May 18-20. On May 30, a blue moon rises at dusk.
The times and dates given apply to mid-northern latitudes. For the most accurate location-specific information, consult online planetariums like Stellarium.
