Astronomy Events for August 2021

These August 2021 astronomy events are rare to happen all in one month! Two planets are in opposition, the best meteor shower of the year on a dark night, and a blue moon provide motivation to plan ahead and spend time under the stars.

Thinking about starting astrophotography? Our getting started in astrophotography has the best tips and techniques to help you get started this month!

August 2 - Saturn at Opposition

Saturn will be at its closest approach to Earth and illuminated by the Sun. This is the brightest it will be all year! Check out our guide on how to see the planets with a telescope or our planetary imaging guide for tips on how to see or capture the ringed planet!

August 8 - New Moon

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.

August 12, 13 - Perseids Meteor Shower

The Perseids meteor shower will produce up to 60 meteors per hour at its peak! Every year, the shower runs from July 17 to August 24. This year the meteor shower will peak on the night of the 12th into the early morning of the 13th. There will be dark skies thanks to the waxing crescent moon setting early in the evening. Find a dark location for the best viewing after midnight.

August 19 - Jupiter at Opposition

Jupiter will be at its closest approach to Earth and illuminated by the Sun. This is the brightest it will be all year! Get your gear ready to observe or image some of its well-known features like the Great Red Spot. See our guide on how to photograph Jupiter for tips and techniques.

August 22 - Full Moon, Blue Moon

This full moon was known by some early Native American tribes as the Sturgeon Moon because the large fish of major lakes like the Great Lakes were easily caught this time of year. This moon is also known as the Green Corn Moon and the Grain Moon.

Normally, there are three full moons in a season. When there is a fourth full moon in a season, the extra one is called a blue moon. It happens once every few years and is where the term "once in a blue moon" came from. Our lunar photography basics video has great tips on how to capture the various phases of the Moon.
