July 2021 Sky Views Include a Comet, Buck Moon, The Pillars of Creation, Meteor Showers & More!

I love summer, but the best month of the year has got to be July. Especially for night sky events this year, 2021. So mark your calendars for these events… you won’t want to miss a single one of them!



July 4th

The morning of July 4th offers the best view of the planet Mercury. Look for this planet low in the eastern sky just before the sun rises. At its peak, Mercury will only be 17 degrees above the horizon, so choose your viewing area wisely looking across an unobstructed horizon.


July 7th

July 7th offers a chance to spot Comet 15P/Finlay. Being controlled by Jupiter’s gravitational pull, this comet orbits the sun once every 6.52 years. For a real-time 15P/Finlay finder, click here.



July 10th

The New Moon is on July 10th offering stargazers the most opportune time to view faint galaxies, star clusters, and more! Depending on your location, look for July constellations in the northern hemisphere to include Draco, Hercules, Corona Borealis and Serpens. Southern hemisphere sky watchers will see Ophiuchus, Scorpius, Norma, Ara, Circinus, Trangulum, Australe and Apus.


The constellation Draco in the northern hemisphere will offer stargazers a peek at Abell 2218 – a cluster of galaxies, as well as the Spindle and Tadpole Galaxies, and the cool, Cat’s Eye Nebula:

The Spindle Galaxy will be bright and spiral shaped with an extended dust disk.

The Tadpole Galaxy is also spiral shaped with a tail of stars making it appear like a tadpole.

The Cat’s Eye Nebula is a planetary nebula made when a solar system’s sun shucks off its outer layers and creates a shell of diffuse gas.


Galaxies viewable within the Hercules constellation include NGC 3210 – a planetary nebula; Hercules A – an active galaxy known for enormous plasma jets; Abell 2151 – the Hercules galaxy cluster that includes NGC 6041 – a giant elliptical galaxy also seen as the brightest galaxy of the bunch; the galaxy cluster Abell 2199 – containing another massive, elliptical galaxy NGC 6166 considered the most luminous of galaxies with a prominent, star halo.


Within the constellations Ophiuchus and Serpens, look for Kepler’s Supernova SN 1604 - an exploded star. Serpens is also home to the Eagle Nebula that contains the majestic Pillars of Creation – a gaseous star forming region that you may be familiar with from the Hubble telescope images.

July 11th

Spot both Venus and Mars within a 3-degree circle including the crescent Moon. Look for the trio at dusk, 29-degrees from the setting sun.


July 13th

Comet 15P/ Finlay will be spotted, zooming across the constellation Taurus.



July 24th

Enjoy the Full “Buck” Moon on July 24th, named so for the time of year that male deer, also known as ‘Bucks,’ start growing their antlers back. Also referenced as the Thunder Moon and the Hay Moon, July’s Buck Moon will be in full moon phase at 10:36pm EST.


July 28th and 29th

The Delta Aquarids Meteor Shower peaks on the night of July 28th and morning of the 29th offering viewers a rate of 20 meteors per hour to spy in the night sky. This meteor shower is produced by leftover debris from comets Marsden and Kracht. Occurring annually between July 8th and August 23rd, meteors will radiate from the constellation Aquarius.


Although meteors will be visible in all areas of the sky, you can find a starting point from the northern hemisphere by drawing a straight line down from the west side of The Great Square of Pegasus to the star, Skat, which lies just above a very bright star called Fomalhaut.


As you can see, the events are spaced out nicely so you can easily fit one… or ALL of them into your schedule. Now let’s hope the weather stays clear and the bugs are caged for your night viewing pleasure.
