What happens when Earth gets between the Sun and the Moon? 🌕
On August 28, 2026, the Full Moon passed through Earth’s shadow in a deep partial . At maximum eclipse, 96.3% of the Moon’s disk was immersed in Earth’s darkest shadow, the umbra—leaving only a small portion of the Moon still illuminated. 🌑
Just 16 days earlier, on August 12, 2026 the same three worlds were aligned differently: the Moon passed between Earth and the Sun, producing a total . These two eclipses occurred during the same eclipse season—a period of about 34.5 days when the geometry of the Sun, Earth and Moon allows eclipses to occur. (Sometimes, a solar eclipse and a lunar eclipse occur about two weeks apart during the same eclipse season—but not always.)
❔️So why don’t solar and lunar eclipses happen every month?
Because the Moon’s orbit is tilted by about 5° relative to Earth’s orbit around the Sun. Most of the time, the Moon passes above or below the alignment needed for an eclipse. Only near its orbital nodes can the Sun, Earth and Moon line up closely enough for an eclipse to occur.
A solar eclipse happens when the Moon’s shadow falls on Earth. A lunar eclipse happens when Earth’s shadow falls on the Moon.
Different shadows. Different perspectives. One celestial story. 🌌

2026 Total Solar Eclipse at Sunset
© Petr Horálek, twanight.org/guest

📷: On 12 August 2026, truly beautiful solar eclipse occured over north pole, visible as total especially from the Spain. I was lucky to observe the eclipse nearby the Tordueles (a small rural hamlet in the province of Burgos), where the totality took about 1 minute and 46 seconds, just less then 1 hour before the sunset. It was truly memorable in many ways and here are some images I took during this special event.
In the about 3-hour-long sequence, the Sun is going to set when the Moon crosses its path in the sky. Leading to the total solar eclipse in the sky, featured by the foreground image of the exact moment when the total solar eclipse over Tordueles, Spain, starts. While the left part of the sky is still bright, out of the lunar shadow, the right one is “swallowed” by it. After the totality, partially eclipsed Sun continues to the horizon, reddening due to dust in the Earth’s atmosphere. Very prominent is also the orange solar corona, caused by reddening of the light traveling through the ash of forest fires in the central Spain.
📎 Used Canon 6D, Sigma 28mm, f3.5 and 1/3200s (partial eclipse, filtered by Baader Astro Solar), f2.5 and 1s (total eclipse), ISO 100, tripod.

Bright Perseids from Sweden

Astronomy Picture of the Day in NASA on August 15, 2026.

Explanation: Known for its bright and fast meteors, the annual Perseid Meteor Shower comes to planet Earth's skies from a radiant in the heroic constellation Perseus. The popular northern summer celestial spectacle is created as grains of dust cast off along the orbit of periodic comet 109P/Swift-Tuttle vaporize in Earth's dense atmosphere, tracing brief, but beautiful streaks through the night. Taken near the shower's peak of activity on August 12, this composite image recorded two bright perseid meteors and one meteor's watery reflection from a location near the coastal village of Grisslehamn, Sweden. Almost as bright as Altair, brightest star on the scene, the meteors appear along with the faint, diffuse background of the Milky Way. This year, the shower's peak activity coincided with a New Moon, so perseid meteor flashes were undiminished by bright moonlight. And for many skywatchers, this night of bright perseid meteors followed their viewing of the silhouette of the New Moon in a much anticipated solar eclipse.

Solar Eclipse in Spain
From Babak Tafreshi, twanight.org/tafreshi : On a project with the city council of Tarragona in Catalonia I traveled to Spain to document my 15th solar eclipse. I set up multiple automated cameras to include iconic Roman, medieval, and cultural icons of the city. More to come, here and on National Geographic.

🌖 The Moon over a World Heritage city.
© Ekkehard Gnadler, twanight.org/guest

⏳ The best lunar views don't always happen at the exact moment of the Full Moon.
From the photographer: “Three hours after the exact moment of the full moon, the moon – 99.8 per cent illuminated – traveled across the wonderful backdrop of the and Hanseatic city of Stralsund in a shallow arc, reaching the horizon before sunrise. Image 1 shows the moon a few minutes earlier, directly behind the tower of St Mary’s Church.”

☄️ One of the most spectacular comets of the decade passed through the inner Solar System in January 2025.
These images were captured by Yuri Beletsky, twanight.org/beletsky from the ESO Paranal Observatory and Las Campanas Observatory in Chile's Atacama Desert.
Comet C/2024 G3 (ATLAS) is a partially disintegrated non-periodic comet that reached perihelion on January 2025.
Unlike periodic comets, which return at regular intervals, a non-periodic comet may never visit the inner Solar System again. Each appearance is a once-in-a-lifetime opportunity to witness an object that has preserved material from the birth of our Solar System over 4.5 billion years ago.

At first glance, the dark side of a crescent Moon seems invisible. But look a little closer...
That soft glow is called ; sunlight reflected by Earth onto the Moon, and then reflected back to us.
So the "dark" part of the Moon isn't dark at all. It's gently illuminated by Earth itself.
Every Earthshine image tells the story of a beam of sunlight completing an extraordinary journey:
☀️Sun→🌍Earth→🌙Moon→👀Your eyes.

💬 Did you catch the July 2026 crescent Moon?
