May astronomy outlook
The only Blue Moon of the year rises

May delivers the remnants of Halley's Comet in the form of a meteor shower, and also the only Blue Moon of the year.

EventDate
Full Flower MoonMay 1st
Eta Aquarids Meteor ShowerMay 6th-7th
New MoonMay 16th
Full Moon (Blue Moon)May 31st

First up in May is the rise of a full moon on May 12th. Native Americans gave this moon the moniker of the Flower Moon, for its spring timing as flower came to bloom.

Soon after, the Eta Aquarids shower reaches its peak. On the Southern Hemisphere this can bring up to 60 meteors an hour, but just 30 for us in the Northern Hemisphere. It is also notable for being the remnants of Halley's Comet.

One of the oldest recorded comets to visit Earth, the shower has been active since April 19th and runs until May 28th, peaking overnight of May 6th.

A New Moon on the 16th offered the clearest view of the stars, free from the moonlight, if our weather around that time is also pleasant.

May ends with a second full moon, the only Blue Moon of 2026 rises as we move into June. Keep an eye on the WeatherRadar throughout to find the best times for a night under the stars.
