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.

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.

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.

The park is located far from any major cities, which means that the night sky is incredibly dark and clear. On a clear night, visitors can see up to 15,000 stars, as well as the Milky Way and other celestial objects. The park even offers astronomy programs and events throughout the year.

Joshua Tree and Milky Way

The Joshua tree is a member of the Agave family and is a type of yucca plant. It has a distinctive, spiky appearance, with thick, twisting branches that reach upwards of 40 feet tall. The tree's trunk is usually short and thick, and it has green, sword-shaped leaves that grow in clusters at the ends of its branches.

The Joshua tree is native to the Mojave Desert, which spans parts of California, Nevada, Arizona, and Utah. It is particularly well-adapted to the harsh desert environment, with long, deep roots that allow it to survive in dry, sandy soils. The tree can also tolerate extreme temperatures, from freezing winter nights to scorching summer days.

The Joshua tree is a unique and fascinating plant that is an important symbol of the Mojave Desert. Its distinctive appearance and cultural significance make it a beloved icon of the American West.

Removing Light pollution Astrophotography Urban Astronomy

The moon and the stars no longer come to the farm. The farmer has exchanged his birthright in them for the wattage of his all-night sun. His children will never know the blessed dark of night.

 — Leslie Peltier in his autobiography

Comparison of original image and final one after removing of the light pollution – night photo of Golden Gate Bridge, San Francisco, California.

Light pollution Astrophotography Urban Astronomy

Photoshop instruction:

Step1: Select the Layers panel and then  duplicate the layer
Step 2: Filter -> Noise -> Median… (about 50 px)
Step 3: Filter-> Blue -> Gaussian Blue… (about 30px)
Step 4: Select original layer
Step 5: Image -> Apply image (Blending: Subtract; Offset: 40)
Step 6: Delete the duplicate layer

See for example video in my other post Comet 103P/Hartley 2 from New York City

Note, that Astronomy Tools has more sophisticated methods to remove light pollution, or you can do some variations of such methods (it depends from size of you original image). You also can apply it only for part of original image.

The other way to remove light pollution is using multiple images, see for example my other post M42 Orion Nebula using iOptron SkyTracker in NYC
