Why Atacama for Stargazing in 2026?

The Atacama Desert in northern Chile offers some of the clearest, darkest skies on Earth. San Pedro de Atacama sits at 2,400 meters elevation with 312 operational nights per year and Bortle Class 1-2 darkness—the darkest classification possible.

2026 brings exceptional opportunities: a total lunar eclipse visible from South America, the Perseids meteor shower under perfect new moon conditions, and Jupiter at opposition in January—one of the best planetary viewing events of the decade.

Best Stargazing Dates in 2026

What You'll See

Jupiter will appear larger and brighter than at any other time in 2026. Through our Unistellar eVscope telescope, you'll observe the Great Red Spot, cloud bands, and all four Galilean moons: Io, Europa, Ganymede, and Callisto. The Orion Nebula is perfectly positioned for deep-sky photography.

🌑 March 2026

Rating: EXCEPTIONAL — Total lunar eclipse visible from Chile!

🌒 Total Lunar Eclipse - March 3, 2026

The Moon will pass through Earth's shadow, turning deep red—the famous "Blood Moon" effect. Visible in its entirety from San Pedro de Atacama. Eclipse begins at approximately 01:30 local time (Chile Summer Time), with totality lasting about 58 minutes. This is the only total lunar eclipse of 2026 visible from South America.

🌌 June-July 2026

Rating: EXCEPTIONAL — Peak Milky Way season in the Southern Hemisphere.

What You'll See

The Milky Way's galactic center reaches its highest point in the sky during Chilean winter. From Atacama's Bortle 1-2 locations, the Milky Way casts visible shadows on the ground. The Carina Nebula, Southern Cross, Alpha Centauri system, and Magellanic Clouds are all perfectly positioned. Temperatures are cold (0-10°C at night) but the seeing conditions are the best of the year.

☄️ August 2026

Rating: EXCEPTIONAL — Perseids meteor shower coincides with new moon—perfect conditions!

Perseids Peak

☄️ Perseids Meteor Shower - August 12-13, 2026

This is the best Perseids viewing opportunity in years. The peak falls on the exact night of the new moon, meaning zero moonlight interference. Expect 60+ meteors per hour from a dark location. While the Perseids radiant is lower in southern latitudes, the exceptional darkness of Atacama more than compensates—you'll see more meteors here than from most Northern Hemisphere locations with light pollution.

💫 December 2026

Rating: EXCELLENT — Geminids meteor shower, though moonlight will be a factor.

Geminids Peak

Supermoon
December 23

The Geminids are typically the most prolific meteor shower of the year, producing up to 120 multicolored meteors per hour. In 2026, the waxing crescent moon sets early, leaving excellent dark sky conditions for the peak nights. Summer in Atacama means comfortable temperatures (15-25°C at night) and good weather stability.

2026 Moon Phases Calendar (Chile Time)

All times are in Chile Standard/Summer Time. Plan your visit during the "dark window" (3-4 days before and after new moon) for optimal deep-sky viewing.

What Makes Atacama Dark Sky Different

🔭 Professional-Grade Equipment

We use a Unistellar eVscope 2 (valued at $5,000 USD)—a smart telescope with Enhanced Vision technology that reveals nebulae, galaxies, and star clusters in real-time color. Unlike traditional telescopes, you'll see deep-sky objects as vivid, colorful images, not faint gray smudges.

📍 Exclusive Dark Sky Locations

We operate from Vallecito and other private locations rated Bortle Class 1-2—darker than most professional observatories. Light pollution from San Pedro (15km away) is undetectable at our observation sites.

👥 Small Group Experience

Maximum 6 guests per tour ensures personalized attention, unrushed telescope time, and intimate stargazing. Most competitors pack 15-20 people into their tours.

📸 Professional Astrophotography

Every guest receives edited astrophotography images of galaxies, nebulae, and star clusters captured during your tour. These are publication-quality images you can share and print.
