Double Rainbow Astrophotography Zion National Park

During my trip to Zion National Park, the weather was far from ideal for astrophotography. Clouds moved quickly across the sky, rain showers passed through the canyon, and the night sky remained hidden.

But sometimes nature offers something unexpected.

After one of the storms, sunlight broke through the clouds and illuminated the moist desert air. What followed was spectacular — a double rainbow stretching above the dramatic sandstone cliffs of Zion.

It made me pause and think: Is a rainbow astrophotography?

Technically, a rainbow is an optical atmospheric phenomenon caused by the interaction of sunlight with water droplets. The Sun — our nearest star — provides the light source. In that sense, this image captures a phenomenon directly created by astronomical light interacting with Earth's atmosphere.

So while it may not show stars, planets, or the Milky Way, it still documents a beautiful example of astronomy meeting atmospheric physics.

Why Does a Double Rainbow Happen?

A primary rainbow forms when sunlight enters a raindrop, bends (refracts), reflects once inside the droplet, and exits — separating into colors.

A secondary rainbow appears when light reflects twice inside the droplet before exiting. This second internal reflection causes:

  • Reversed color order (red on the inside, violet on the outside)
  • A fainter and wider outer arc
  • A darker region between the two rainbows known as Alexander’s Band

Double rainbows are less common because they require:

  • Strong, low-angle sunlight (often late afternoon)
  • Large numbers of evenly distributed raindrops
  • The observer positioned with the Sun behind them

In desert environments like Zion, storms can be brief but intense — creating perfect conditions when sunlight returns.

Even though this was not the astrophotography session I had planned, this moment reminded me that sky photography is not limited to night. Sometimes the most powerful celestial light comes from the Sun itself.

Green Sky Utah Airglow Astrophotography Canon 60Da

The sky is green, the night is dark - as simple as possible. This photo was done at Bryce Canyon, Utah. Canon 60Da, EF16-35mm f/2.8L II USM, 30.0 sec; f/3.5; ISO 6400

Green Sky Utah Airglow Astrophotography Canon 60Da
The natural moonless night sky is dark but not black; it is not even blue (no scattering light from sun and moon). Earth atmosphere  emits green, red, orange, yellow light- Airglow!

About 60% of the natural brightness of the night sky at zenith is made up of Airglow. Maximum brightest usually appears at about 10-15 degrees above the horizon, because of the greater the depth of atmosphere at this angle. Airglow is not always uniform. Gravity waves may create considerable variation of Airglow brightness.

You can see Airglow only in real dark sky, but naked eye could not recognize colors. Photos with long exposure able get the colors of Airglow.

The usually dominant color of airglow is green originated from molecular oxygen at 90 to 100 km high. Orange and reddish hue caused by atomic oxygen in 150-300 km above the ground, Yellow light comes from sodium atoms in a layer at about 90 km.

Utah Astrophotography

The sky calls to us.
If we do not destroy ourselves,
we will one day venture to the stars.
--Carl Sagan


Utah is one of the best places in the world for landscape astrophotography. Bryce Canyon National Park offers exceptionally dark skies, dramatic rock formations, high elevation, and some of the most unforgettable Milky Way views in the United States.

All photos in this post were taken during my trip to Utah, mostly around Bryce Canyon National Park, under very dark, crystal-clear skies with strong natural airglow.

Milky Way and Airglow Over Utah Road – Left Turn Sign

This image captures a lonely Utah road under one of the darkest skies in the United States. A bright Left Turn road sign stands illuminated in the foreground, leading the viewer’s eye toward the distant mountains and the dramatic rise of the Milky Way. The Galactic Core appears extremely bright — a vertical column of stars, dust lanes, and glowing nebulae stretching up into the sky. Natural green airglow adds a surreal glow near the horizon, giving the scene an almost otherworldly atmosphere.

Eruption of the Milky Way Over Utah Mountains

This photo is a zoomed-in view of the previous scene, focusing entirely on the mountains and the glowing rise of the Milky Way. Without the road and sign, the composition becomes even more dramatic — the landscape looks like a dark silhouette beneath an explosive burst of galactic light. The bright Galactic Core appears almost like a cosmic eruption, with dense star clusters and dusty nebulae rising vertically from behind the mountains. Subtle airglow adds a soft glow along the horizon, making the scene feel like it is from another planet.

Vertical Milky Way and Airglow Over Utah Mountains

This single, vertical shot captures the Milky Way rising straight up over the Utah mountains, forming a dramatic column of light. A soft layer of green airglow adds a gentle tint near the horizon, while the mountain silhouette anchors the composition. Simple and clean, the image shows the classic beauty of a vertical Milky Way rise — one of the most iconic views in astrophotography.

Night Parking Under the Milky Way

This image captures a quiet night parking area in Utah, illuminated softly by a few scattered lights, with cars resting under the sky. Even with the artificial lighting, the location is so dark and pristine that the Milky Way remains fully visible above the trees, stretching brightly across the night. The gentle glow from the parking lot barely affects the sky — a rare reminder of how extraordinary Utah’s natural darkness truly is.

With the silhouettes of trees framing the scene and the Galactic Core rising above the parked cars, the photo blends everyday elements with the cosmic grandeur of the Milky Way, turning a simple parking lot into a stunning nightscape.

Big Dipper, Small Dipper and Natural Airglow

This photo focuses on two of the most iconic northern constellations — the Big Dipper prominently centered in the frame, and the Small Dipper (Ursa Minor) appearing in the upper-right corner. Together, they form one of the best natural guides for finding true north in the night sky.

The two stars at the edge of the Big Dipper’s bowl — Merak and Dubhe — point directly toward Polaris, the North Star, which anchors the end of the Small Dipper’s handle. Even without labels, you can clearly see how the geometry of the sky reveals direction.

The scene is framed by the silhouettes of trees, and a gentle layer of green and red airglow adds soft, natural color to the background. It’s a beautiful combination of astronomy and landscape — a quiet Utah night where celestial navigation and atmospheric glow meet in a perfect astrophotography moment.

Astronomy Rangers Night Sky Program at Bryce Canyon

This photo captures a beautiful moment during the night astronomy program at Bryce Canyon National Park. In the foreground, a telescope stands ready as visitors gather around it, waiting for their turn to look through the eyepiece guided by the park’s Astronomy Rangers. Soft red lights illuminate the area — specially used to preserve night vision during stargazing events — creating a warm glow against the darkness. Behind the viewing area, a small building and the dim outline of the road can be seen, while the surrounding trees frame the scene. Above it all rises the spectacular Milky Way, arching brightly across the sky and reminding everyone why Bryce Canyon is one of the premier dark-sky locations in the world.

Martian Landscape from Bryce Canyon

This single frame from my larger Bryce Canyon panorama focuses tightly on the brightest and most dramatic region of the Milky Way — the galactic center. The rugged hoodoos and canyon walls glow with warm, earthy tones, creating a landscape that looks almost extraterrestrial, as if photographed on Mars rather than Utah. The towering cliffs and formations rise into the night, illuminated subtly by starlight, while the dense core of our galaxy burns overhead in deep gold and orange hues. This combination of Bryce Canyon’s unique geology and the immense Milky Way shining above produces a surreal, otherworldly scene that feels like a gateway to another planet.

Milky Road – Dark Dust Lanes in the Galactic Plane

This single-frame capture reveals the Milky Way rising without any foreground landscape, allowing the viewer to focus entirely on the complex structure of our galaxy. The darker central band — often called the “Great Rift” — is clearly visible as thick clouds of interstellar dust and gas absorb the light from millions of stars behind them. This natural dark lane creates the illusion of a cosmic “road” stretching upward through the sky, giving the image its fitting name: Milky Road. Even without the canyon scenery, the depth, contrast, and clarity of the galactic core make this one of the most dramatic astro-portraits of the night sky.

Utah Backyard Astrophotography – Milky Way Over the Fence

This final photo was taken right from the backyard of the house where we stayed for the night. The scene includes the wooden fence, trees, grass, and a few small backyard details illuminated by nearby light — ordinary objects that become magical under Utah’s incredible dark sky.

Above this quiet backyard, the Milky Way rises in full brightness, stretching across the sky like a glowing river of stars. Even far from the national park viewpoints, Utah’s night sky remains phenomenally dark and clear. The strong Milky Way structure, with its dust lanes and bright core, shows how little light pollution there is in this region.

It’s a reminder that breathtaking astrophotography does not always require a dramatic landscape — sometimes an ordinary backyard becomes extraordinary when the galaxy appears right overhead.

Airglow Astrophotography - Bryce Canyon National Park - Sunset Point

Night sky with green airglow, the Milky Way, Seven Sisters (Pleiades) and Andromeda Galaxy is on the top; hoodoos, caused by erosion over many millennia, are on the bottom. This photo was done from my trip to Bryce Canyon in Sunset Point.

Beginner tip: if the night sky looks green in very dark conditions, it is usually natural airglow — not a mistake. Truly dark skies are rarely blue. Do not use Photoshop to make the sky “blue”; green, yellow, and red tones are natural colors of the dark night sky.

On this picture you can see a lot of green color on the sky. If this is real color or just effect of camera filter? This question directly connected to other question “What is natural color of night sky?”

I started to learn astronomy many years ago reading the book with black and white pictures. So in these books I didn't see color picture of the natural sky. Most of time I was living in big city with a lot of light pollution, and I am not able to see natural color of sky.

Still remember when first time recognize that some starts has color and after that read article about color of stars cannot be green. After that article I assumed that green color is very rear on the sky. But this is not correct.

Most of Comet Tails has green color. Some Nebular are green too. Northern Light mostly has green colors. But Northern Light visible only near North Pole, comets are rear so still assume that this green colors are exceptions. When I started see Internet picture I saw a lot of strange colors so assuming that these is Photoshop. Especially after reading article how to remove light pollution in Photoshop. And only made some my own pictures I recognized that green color from Airglow effect is gives a lot of green on the natural sky. So a green color is pretty common on the natural sky too.

Utah Astrophotography and Astronomy - Bryce Canyon National Park - Milky Way

Bryce Canyon National Park is one of the most spectacular places in the United States for both astronomy and night-sky photography. The park's high elevation, dry air, and very low light pollution make it one of the clearest dark-sky locations in the Southwest.

One of the most iconic spots is the Bryce Canyon National Park entrance sign, which sits in an open area with a full view of the sky. On this night, the Milky Way stretched vertically above the entrance, glowing with beautiful green airglow — a natural atmospheric phenomenon often visible only at the darkest locations.

The combination of the illuminated stone entrance sign, tall pine trees, and the bright core of the Milky Way creates a perfect nightscape scene that feels both welcoming and otherworldly.

Milky Way over Sunset Point of Bryce Canyon - Astrophotography

A still more glorious dawn awaits.
Not a sunrise, but a galaxy rise.
A morning filled with 400 billion suns, the rising of the milky way.

Carl Sagan

Bryce Canyon National Park is one of the best places in the United States for night-sky observation and astrophotography. Its high elevation and extremely low light pollution create truly spectacular skies. On the night I photographed this panorama at Sunset Point, the Milky Way rose above the famous sandstone hoodoos with a natural green glow — the unmistakable signature of atmospheric airglow.

This image continues my series of National Park night-sky photographs, showcasing some of the darkest and clearest skies in America.

  • Exposure: 30 seconds each
  • Aperture: f/3.5
  • ISO: 6400
  • Location: Sunset Point, Bryce Canyon National Park

The faint green glow visible in the sky is natural atmospheric airglow, not light pollution — one of the signatures of truly dark skies.


Final Thoughts

Standing at Sunset Point that night, the view felt almost unreal — as if the landscape belonged to another planet. The brightest and most dramatic part of the Milky Way rose vertically above the canyon, glowing like a celestial pillar of light. This is the galactic core, the dense center of our galaxy filled with star clouds, dust lanes, and billions of stars — and here it hovered directly above the towering hoodoos of Bryce Canyon.

The canyon cliffs and scattered trees were softly illuminated by the starlight, creating an otherworldly, dream-like scene. The night was so dark and so clear that the Milky Way appeared almost three-dimensional, climbing dramatically into the sky. Combined with the ancient rock formations below, the entire view formed a fantastic and unforgettable night landscape.

This image remains one of my absolute favorites — a rare moment when the glowing heart of our galaxy rises above Bryce Canyon, blending Earth and cosmos into a single breathtaking scene.
