What's Up In The Sky Now?

June, 2026

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

Our days are getting to their longest point as we approach the beginning of Summer, which means less hours to enjoy the night sky. I just continue to hope for clear skies!!!

Mercury

MERCURY - has its best evening showing this month but drops below the western horizon shortly after sunset. This little planet pairs nicely with Venus & Jupiter this month, so watch the western horizon near sunset. It reaches its greatest elongation (longest distance from the Sun as viewed from Earth) on the 15th. June 16 at 10 PM.

Venus

VENUS - This month our Evening Star displays a 77% disk. Early in the month it leads Jupiter to the western horizon but then lets Jupiter take the lead by mid-month. On the 17th there will be a daytime occultation of Venus by the Moon at about 2:45 PM CDT. Try using binoculars to watch this event. Venus occultations are fairly uncommon with the last one seen in the US in April 2024.

Earth

EARTH  - SUMMER SOLSTICE happens on the 21st at 3:25 AM CDT.

Mars

MARS - The red planet rises about 90 minutes before sunrise and should have a good viewing opportunity on the 12th. Look for Mars near the Pleiades in the E-NE on the 23rd. June 12th at 4:30 AM. Neptune is in the top right corner of this image.

Jupiter

JUPITER - Continues to head towards a solar conjunction next month at the end of July. Best viewing this month is shortly after sundown, usually with Venus nearby.

Saturn

SATURN - Remains in our eastern morning sky, so set your alarm clock for those early morning hours to see this beauty.

Uranus

URANUS - Is not visible the first half of June but finally shows itself by the 15th as it rises about an hour before sunrise.

Neptune

NEPTUNE - This blue planet finally appears in the night sky after midnight.

The Moon

  • 08 – 3rd / Last quarter
  • 14 – NEW Moon at 9:54 PM CDT and is called a “Super New Moon” as it is at its closest point to Earth.
  • 21 – 1st quarter
  • 29 – FULL Moon at 6:56 PM CDT, known this month as “Micro Full Moon” as it is at its furthest distance from Earth.

Meteor Shower

  • None this month

Comet Watch

  • Comet 10P / Tempel (Tempel 2) – is predicted to have its best showing since 1967. It is expected to reach peak brightness in early August. It was discovered in 1873. It takes about 5.4 years for it to complete one orbit around our Sun.
  • Best viewing will be late in the night into the early morning hours, after it gains altitude above our southeastern horizon. Scientists suggest one could use binoculars and/or small telescopes to easily see this comet.
