EYE IN THE SKY
MONDAY, JULY 20, 2026
Tonight the Moon has grown into a beautiful waxing crescent, about 37% illuminated, and is approaching First Quarter, which occurs tomorrow. This phase provides outstanding contrast along the Moon's terminator—the line dividing lunar day and night—making craters and mountain ranges especially dramatic through binoculars or a telescope.
After Sunset
Look to the western sky for brilliant Venus, still dominating the evening twilight.
The Moon has now moved eastward into Virgo and will appear near the bright blue-white star Spica, creating another attractive pairing for skywatchers.
Later Tonight
The Summer Triangle—Vega, Deneb, and Altair—rides high overhead. From darker skies west of Buckeye, the Milky Way stretches through this region, revealing countless stars, nebulae, and dark dust lanes.
Meteor Watch
The Perseid Meteor Shower continues to build. While the peak is still weeks away, patient observers may catch a few early meteors after midnight.
Saturn shines in the southeastern sky.
Mars rises before sunrise in the east.
Early risers will enjoy some of the steadiest atmospheric conditions for planetary viewing.
Quantum Space Fact of the Day
Exactly 57 years ago today—July 20, 1969—Apollo 11 astronauts Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. Remarkably, the Moon's phase on July 20, 2026 closely matches the lunar phase from that historic day, giving us a chance to see the Moon under nearly the same lighting conditions experienced during humanity's first lunar landing.
Tonight's Photography Challenge:
Capture the waxing crescent Moon with Earthshine just after sunset, then return after full darkness for a wide-angle image of the Summer Triangle and the Milky Way.
