Moon in Two Lights: A First Quarter Day-Night Portrait

Astrophotographer Zachary Cooper captured the first-quarter Moon using a small refractor and a dedicated camera, taking many ultra-short exposures for the sunlit side and longer exposures to reveal earthshine, then merging the frames into a single image that shows dramatic daylight shadows at the terminator and the faint glow on the dark side—an image that mirrors how Artemis II views the Moon and reveals the Moon’s dual-night/day character.

Earthshine Moment: Christina Koch Captures Earth from Artemis II Orion Flight

NASA posted a video captured by Artemis II astronaut Christina Koch showing Earthshine—sunlight reflecting off Earth—from about 33,800 miles away on the Orion spacecraft during the 10-day lunar flyby; Koch’s footage comes as the Artemis II crew (Reid Wiseman, Victor Glover, Jeremy Hansen, Koch) traveled farther from Earth than any humans in history, surpassing Apollo 13, and the clip was released around Earth Day.

Five Science Facts Revealed by Moon Watching

Five Science Facts Revealed by Moon Watching

Watching the Moon reveals key scientific facts: Earth is round, not flat; its shadow during lunar eclipses is spheroidal; the Moon's orbit is elliptical, causing variations in its apparent size; Earth’s reflectivity can be gauged through Earthshine on the Moon; and the Moon's surface features, like mountains and craters, are visible during eclipses. These observations have helped us understand Earth's shape, the Moon's orbit, and Earth's reflectivity.

Crescent Moon and Jupiter Alignment on July 23

Crescent Moon and Jupiter Alignment on July 23

On July 23, a crescent moon will be visible near Jupiter in the early morning sky, with the moon illuminated by Earthshine and Jupiter showing its four brightest moons. The event offers a great opportunity for skywatchers to observe celestial objects, especially with telescopes or binoculars, and to enjoy related phenomena like Earthshine and the Pleiades star cluster.

Celestial Trio: Mars, Venus, and Moon Visible on Summer Solstice

Celestial Trio: Mars, Venus, and Moon Visible on Summer Solstice

This year's Summer Solstice will feature a rare celestial alignment of Earth, Mars, and Venus, visible in the night sky close to the crescent Moon. The parts of the Moon usually hidden by lunar night will glow with an eerie light called Earthshine, caused by sunlight reflecting off Earth's atmosphere and then off the Moon's surface. A small telescope or binoculars can provide a better view of the lunar surface, including mountains and craters. The alignment can be seen on Thursday evening, with Venus clearly visible and Mars slightly harder to spot.

Catch Jupiter and its Galilean satellites shine near the crescent moon tonight.

Catch Jupiter and its Galilean satellites shine near the crescent moon tonight.

Early risers and night owls on Flag Day (Wednesday) morning will be treated to a lovely "celestial tableau" low in their eastern sky as the brilliant planet Jupiter hovers close to the right of a slender waning crescent moon. Jupiter currently rises about two and a half hours before the sun and is currently in the constellation Aries. Binoculars will bring out the Earthshine effect even more than with the unaided eye and will impart a three-dimensional effect to the moon. On this particular morning, should you be looking at Jupiter through a pair of steadily held binoculars or a telescope, you'll be able to see all four satellites.

"Experience the Enchanting Da Vinci Glow on the Moon for Three Days"

A unique crescent moon lit by Earthshine, also known as the "Da Vinci Glow," will be visible in the sky for the next three days. Earthshine is the phenomenon of light reflecting off the face of the Earth, illuminating the moon. This allows stargazers to see the whole moon, even though it should be covered by the Earth's shadow. The best time to see it is during a waxing or waning crescent, and clear skies are necessary. The phenomenon was first described by Leonardo da Vinci, who used his artistic insights and knowledge of geometry to explain it.

Catch May's Spectacular Earthshine Tonight.

Earthshine, a phenomenon where sunlight reflects off the Earth's surface and illuminates the unlit portion of the Moon, can be seen during specific phases of the lunar cycle. It is most visible during the waxing or waning crescent phase and is caused by sunlight reflecting off the Earth's surface and then being reflected back onto the Moon. Earthshine is also known as the Da Vinci glow and can vary in intensity depending on atmospheric conditions, Earth's reflectiveness, and the observer's location. No special equipment is required to see it, and it can be a great opportunity for lunar photography.

"Experience the Da Vinci Glow and Earthshine on the Moon: Viewing Dates Revealed"

"Experience the Da Vinci Glow and Earthshine on the Moon: Viewing Dates Revealed"

The "da Vinci glow" or "Earthshine" is a spooky phenomenon that occurs when the moon is a thin crescent in the sky, visible during the first and last days of the moon's orbit around Earth. It is the faint image of the full moon visible next to the portion of the moon lit by the sun. The phenomenon is called the "da Vinci glow" because Leonardo da Vinci figured out that sunlight reflected from Earth was responsible for the image. The da Vinci glow is best seen a few days before and after a new moon, right after sunset or before sunrise.
