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

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.

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.

Final Thoughts

Photographing the Milky Way above the Bryce Canyon entrance sign felt like capturing a welcome message from the universe itself. The bright galactic core, the green glow of atmospheric airglow, the pine trees, and the warm stone sign created a perfect blend of Earth and cosmos.

This is still one of my favorite Utah nightscape images — a reminder of how magical Bryce Canyon becomes after sunset.

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.

Photo Settings

  • Panorama: 7 vertical shots stitched together
  • Camera: Canon 60Da
  • Lens: Canon EF 16–35mm f/2.8L II USM
  • 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.
