The Milky Way Over the Sailing Stone: A Night Under the Stars at Racetrack Playa, Death Valley National Park, California

Racetrack Playa is a place of natural intrigue. Situated in the heart of Death Valley, this dry, cracked lake bed is renowned for its "sailing stones" — large rocks that mysteriously move across the playa, leaving long tracks behind them. For decades, these stones puzzled scientists and visitors alike, as no one could quite figure out how these hefty rocks glided across the desert floor. It wasn’t until recently that a rare combination of ice, water, and wind was identified as the culprit behind their movement.

Panorama 27 photos, Canon EOS Ra, EF16-35mm f/2.8L II USM Lens, f/2.8, ISO-25600, 20 seconds each photo.

When night falls at Racetrack Playa, another marvel unfolds overhead. With its location in one of the darkest national parks in the U.S., the sky above Death Valley becomes a portal to the universe. The absence of light pollution allows for one of the most pristine views of the Milky Way, an ocean of stars arching across the sky, giving photographers an ideal canvas for astrophotography.

One interesting detail in this panorama is the orientation of both the sky and the sailing stones. Near the horizon you can recognize the Big Dipper (Ursa Major) in a low position, while the Little Dipper (Ursa Minor) is also visible, with Polaris (the North Star) marking the direction of true north.

At this low altitude, the familiar shape of the Big Dipper appears more flattened than usual. One of its stars, Phecda, is not clearly visible, but the remaining main stars are still recognizable, allowing the asterism to be identified.

Racetrack Playa is located at a latitude where the Big Dipper is circumpolar, meaning it can be seen throughout the entire year. As the night progresses, it slowly rotates around Polaris, changing its position while always remaining above the horizon.

The movement of the stones in the foreground adds another layer of interest. The main sailing stone in the center shows a trail roughly aligned with the north–south direction, appearing to move from the direction of Polaris toward the observer. However, a second stone on the right side of the frame reveals a different trajectory, with its path running almost perpendicular to the main stone’s trail.

This variation highlights the complex and delicate conditions behind the sailing stones phenomenon. Their motion depends on a rare combination of thin ice sheets, shallow water, and shifting wind, allowing different stones to move at different times and in different directions, creating a network of intersecting trails.

Together, the scene presents a striking contrast: the sky above follows predictable celestial motion around Polaris, while the desert floor records irregular and transient movement. It is a rare moment where celestial order and natural variability can be observed in a single frame.

Standing in the silence of Racetrack Playa under the brilliant Milky Way, one feels both humbled and uplifted. The ancient stones, moved over time by forces unseen, seem like they are part of a larger cosmic ballet, just as the stars above trace their eternal paths through space. In that quiet desert night, there is a profound sense of stillness, yet the sky and stones speak of movement across millennia.

Milky Way Rainbow Panorama Canon EOS Ra over Bethel Catskill NY

This image captures a full arch of our galaxy — often called the Milky Way Rainbow. It is my first full-sky panorama of the Milky Way made with the Canon EOS Ra, and another step in testing the camera’s impressive astrophotography performance.

The Canon Ra handles high ISO extremely well, producing low-noise results even at ISO 20,000. Using short 5-second exposures helped avoid star trailing and made the 20-shot panorama quick to capture. A dedicated contrast-enhancing filter helped bring out the structure of the Milky Way, and the final image was created by stitching all frames together in Photoshop.

The foreground shows tall grass with a line of forest farther in the distance. A bit of light behind the camera softly illuminates the landscape, creating depth and atmosphere while preserving the natural nighttime look. Above the scene, the Milky Way forms a complete glowing arch across the sky — a true “rainbow” of our galaxy rising over Bethel and the Catskill region of New York.

Milky Way Panorama Astrophotography

There are couple of Milky Way panoramas which I did previously. There are Milky Way Rainbow from West and East of North America, Panorama in South America Chile and Milky Way Bow in Equator Galapagos. The photos of panoramas done during of couple of years. All places have best dark sky on Earth, photos were done during new moon. I used about the same technology – about 20-30 photos for one panorama. It took about 30 – 40 minutes (one photo was about 30 second, Canon 60Da with Canon Lens EF16-35mm, F/2.8). For post processing I used Photoshop to stitch all photos to one panorama. Challenge were that it was new places, when I never bean before, and very limited time.

This is panorama of 40 images which were done during my trip to Arches National Park. I really like this trip, and I believe that   Arches National Park is one of the best place for landscape astrophotography. It is paradise for astrophotography – really dark sky (during new moon) and fantastic landscaping.

While Mount Desert Island is not heavily populated and is remote, but some light pollution exists. So, some places in Acadia National Park are just with good dark sky. But some places are having amazing sky! Sand Beach, while just a 290-yard-long beach inlet between granite mountains, has a spectacular view of the night sky. On the Bortle Dark-Sky Scale, this place has “Class 1” (out of 9) is absolutely, naturally dark — the darkest skies on Earth!

This sea is my sea, this land is my land, this sky is my sky, this Milky Way is my Milky way.

Not so much were changes on Galapagos Islands during last 3 millions years!

The marine iguana (Amblyrhynchus cristatus), also known as the sea iguana, saltwater iguana, or Galapagos marine iguana, is a species of iguana found only on the Galápagos Islands (Ecuador) that has the ability, unique among modern lizards, to forage in the sea, making it a marine reptile.


Milky Way casting shadows in the Atacama Desert Chile – extremely dark sky astrophotography panorama
Panorama - Milky Way Shadow - Chile Astrophotography

Milky Way casting shadows – for all my live don’t see many times. Need very dark sky, no moon, no light pollution. Also, when doing the photo of Milky Way panorama, I usually add extra light to see landscape. This was exception. Very dark sky – Chile Atacama Desert has one of the best skies for observation. On the astronomical tour had one request – no light. Location is desert oasis with trees. Scorpius and Sagittarius and Jupiter are close to zenith. As result on the photo you can see diffuse shadows from trees casing by Milky Way. Really, there is the place where the Milky Way casts a shadow!

This is my first photo of Milky Way Rainbow with Canon EOS Ra. I am continue testing Canon Ra astrophotography camera. Canon Ra has High ISO performance with reasonable low noise levels (Topaz DeNoise AI allow minimize noise level). So even 5 sec photos with ISO 20,000 gives very nice result for night landscaping. Because of 5 sec shots – photo time is pretty fast. Special filter gives good contrast for Milky Way. Photoshop allows combine all 20 photos to one Milky Way rainbow panorama.

Milky Way and Zodiacal Light panorama over Bolivia Andes at 4020 meters – black and white night sky astrophotography

The photo captures a view of the night sky over the Bolivia. 2 hours after sunset (elevation: 4020 m / 13190 feet). Canon EOS 60Da, 25 sec., Canon Lens EF16-35mm, f/2.8, ISO 6400, panorama of 20 images. 

Because our eyes are less sensitive to color in low light conditions, a black and white photo more closely approximates what our eyes can see at night (compared to a color photo).

The black and white photography highlights the stark contrast between the dark night sky and the glowing band of the Milky Way. The Milky Way, a dense band of stars and interstellar dust, stretches across the sky in a white arc. 

If you look closely, you can also see a faint, diffuse glow stretching up from the horizon. This is the Zodiacal Light, a ghostly band of light caused by sunlight reflecting off interplanetary dust particles in our solar system. 

Taken together, the Milky Way and Zodiacal Light create a breathtaking scene that reminds us of the immense scale and beauty of the universe we inhabit. It is a testament to the power of nature and the wonders that can be discovered by simply looking up at the night sky.

The photo of the Milky Way and Zodiacal Light is an example of the beauty that can be found in the natural world. It is a reminder that there is always more to discover and explore, both here on Earth and beyond.

Milky Way Casting Shadows - Chile Astrophotography - San Pedro de Atacama Celestial Explorations Star Tour

We all know that the Sun and the Moon cast shadows. But can the Milky Way itself be bright enough to do the same? In extremely dark locations, the answer is yes.

This panorama was captured during the San Pedro de Atacama Celestial Explorations Star Tour in northern Chile. On the image you can clearly see shadows of the trees cast only by the Milky Way — something that is possible only under the darkest skies on Earth.

According to the Bortle Scale of night-sky brightness, this region rates as a Class 1 – Excellent Dark-Sky Site. Here, the Scorpius–Sagittarius region of the Milky Way is so bright that it produces detectable diffuse shadows on the ground. It is an extremely rare and unforgettable sight.

For observers hoping to witness Milky Way shadows themselves, sky conditions matter as much as sky darkness. A Bortle Class 1 site is essential, but it is usually not sufficient on its own. The Galactic Center, located in the Scorpius–Sagittarius region, must be well above the horizon, where the Milky Way’s surface brightness reaches its maximum.

Shadows are not produced by individual stars, but by the combined light of billions of stars concentrated toward the Galactic Core. When this region is high in the sky and atmospheric extinction is minimal, the Milky Way can generate subtle but detectable contrast between illuminated and shaded areas on the ground.

The effect becomes even more noticeable when a bright planet such as Jupiter is present near the Milky Way, subtly reinforcing the overall illumination. Only when these conditions align — a true Bortle Class 1 sky, the Milky Way core high above the horizon, and additional planetary light — do Milky Way shadows become realistically observable.

Near the horizon, green and red airglow is visible — a natural atmospheric luminescence often seen in extremely dark locations. The brightest “star” in the middle of the panorama is actually Jupiter.

This photograph was captured in the Atacama Desert, Chile—one of the premier astrophotography locations on the planet. Many of the world’s leading observatories operate here (the other major hub is Hawai‘i’s Mauna Kea).

The image was taken near a small oasis where a few trees are present. It is astonishing to stand in near-total natural darkness and see shadows cast not by any artificial light, but by the bright central bulge of the Milky Way and the planet Jupiter.

This is what a true Bortle Class 1 sky looks like — the very definition of a perfect dark-sky environment.

Experiences like this reveal the Milky Way not as a distant backdrop, but as a luminous structure capable of shaping the landscape itself — a reminder of what the natural night sky can truly be.
