What's Up In The Sky Now?

July, 2026

Our Solar System - notes by JoAnn Cogil, President of the Des Moines Astronomical Society

July brings warm weather which makes it nicer to be outside at night to look at our night sky.

Mercury

MERCURY - by the last few days of July, this little planet returns to our morning sky after an inferior conjunction (when it stands between the Sun and Earth) on the 12th.

Venus

VENUS - remains our ‘Evening Star’ until October. For now, it continues to shine brightly in the west, but you may need to catch it quickly in the evening twilight as it sets soon after sunset. The bright star Regulus in Leo is near Venus on the 1st day of the month about one hour after sunset with the 2 becoming closer together on the 8th.

Earth

EARTH  - on the 4th, we celebrate the 250th Anniversary of the signing of our Declaration of Independence!!

Mars

MARS - the red planet draws closer to Earth this month as it continues its orbit around the Sun, which allows this tiny planet to slowly brighten in our skies. On the 11th, look for a wonderful grouping of Mars, Uranus, Moon and the bright star Aldebaran in the E-NE sky about 4:00 AM. The Pleiades star cluster looks on from above. 

Jupiter

JUPITER - we say ‘goodbye’ to this beautiful planet and its moons as it leaves our evening skies after July 9th. Has a solar conjunction on the 29th.

Saturn

SATURN - continues to rise earlier each night which puts it into darker skies instead of rising closer to sunrise. By mid-month, it will be rising after midnight.

Uranus

URANUS - has a close encounter with Mars on the 4th; try looking for Mars first, then Uranus.

Neptune

NEPTUNE - still need binoculars or a telescope to see this pretty blue planet with best viewing after 3 AM as it stays near Saturn.

The Moon

  • 07 – 3rd / Last quarter
  • 14 – NEW Moon at 4:43 AM CDT
  • 21 – 1st quarter
  • 29 – FULL Moon at 9:35 AM PM. 


The full moon this month is known as the ‘Buck Moon’ for the new antlers that are beginning to emerge on the buck deer. Also known as the ‘Thunder Moon’ and ‘Hay Moon’. On the evening of the 16th, our Moon, at a waxing crescent phase with only a slim lunar disk showing, sits next to Regulus, the bright star in the constellation Leo the Lion. The pairing of the Moon and Regulus is always a nice event to see. This night we get the added fun of Venus nearby.

Meteor Shower

  • Perseids meteor shower – begins the middle of July with its course running from 7/14 to 8/24. It will peak on the night of August 12th & 13th which is exciting as this is the night of a new moon, so our night sky will be dark. We could see anywhere from 30-50 meteors per hour, even upwards of 90-100 due to the darkness of the sky on peak night. Meteors from this shower can be colorful & bright with possible persistent trains. The Perseids is the most popular meteor shower of the year. Meteors come from Comet 109P/Swift-Tuttle which was discovered in 1862. It has an orbit around the Sun of about 130-133 years and was last seen from Earth in 1992. Scientists predict this comet could be seen by our eyes without the use of telescopes in 2126, only a century away.

Comet Watch

  • Comet 10P/Temple (or Tempel 2) – can be found above the southern horizon in the constellation Capricornus by mid-July. It is best seen after midnight. By August 2nd, it has its closest approach to the Sun and then will be closer to Earth a couple days later. This could be the brightest showing of this comet since 1967.
