Best Astronomy Events for July

These July astronomy events are a great way to stay connected with the universe and stargaze or image all month long! If you are looking to get started in astrophotography, July is a perfect month as we are in the peak of Milky Way season. Milky Way season is when the core of the Milky Way rises earlier in the night making it easier to capture!

Moon Phases, Planets, and Meteor Showers July 2021

July 4 - Mercury at Greatest Western Elongation

Mercury will be at its highest point above the horizon in the morning sky making this is the best time to view Mercury. It will be low in the eastern sky just before sunrise.

July 10 - New Moon

This phase occurs at 01:17 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

July 24 - Full Moon

This full moon was known by some early Native American tribes as the Buck Moon because the male buck deer would begin to grow their new antlers at this time of year. This moon has also been known as the Thunder Moon and the Hay Moon.

July 28, 29 - Delta Aquarius Meteor Shower

You will have the chance to see about 20 meteors per hour at its peak. This year it peaks on the night of July 28 and morning of July 29. Because the Moon will still be nearly full, it might make it hard to see many meteors at once. For the best viewing, find a dark sky site near you and look up after midnight!
