Join Sky & Telescope in Chile — the “astronomy capital of the world” — from October 12 to 23, 2022. Our group will visit world-class observatories, see breathtaking landscapes, and observe the southern sky in crystal-clear night skies.

Admit it — you've always wanted to go south of the equator to take advantage of the extraordinary celestial sights of the southern sky. But you’ve never quite figured out the logistics of getting there, let alone how you’d lug your telescope through airports and customs.

Here’s your chance to have it all — and you can leave the scope at home! Sky & Telescope is heading to Chile for a 10-day, 9-night adventure to some of the most astronomically famous and stunning locales on the planet. Join S&T Editor in Chief Peter Tyson next October 12–23 on what promises to be an over-the-top celestial adventure.

With its high mountains, clear skies, and dry air, northern Chile is a mecca for both professional observatories and nighttime stargazing — and you'll get to see plenty of both. The trip combines rare, behind-the-scenes tours of major telescopes (including visits to the Very Large Telescope and the amazing ALMA radio-telescope array) with three nights of stargazing at privately owned facilities that cater to amateur observers. You can leave the telescope at home, because all the observing gear will be there waiting for you!

Here are some of the telescopes you’ll use to observe the southern sky during our visit to SPACE (San Pedro de Atacama Celestial Explorations).

Planned Itinerary for the 2022 Chile Astronomy & Stargazing Tour

Day 1 (Wednesday, Oct. 12): Depart for Santiago
Depart from your home city on an overnight flight to Santiago, the capital of Chile.
Overnight flight (meals aloft)

Downtown Santiago
Santiago is a vibrant, modern city of more than 5 million.

Day 2 (Thursday, Oct. 13): Santiago
Arrive this morning in Santiago and transfer to our 5-star hotel located in one of the most exclusive quarters of Santiago. After a short afternoon orientation, we’ll visit Chile’s National Astronomical Observatory. Operated by the University of Chile’s Department of Astronomy, the observatory is situated on Cerro Calán, which offers breathtaking views of the city. Upon return to our hotel, we’ll gather for a welcome dinner and orientation.
Plaza El Bosque (D)

Day 3 (Friday, Oct. 14): La Serena
Depart Santiago on a flight to La Serena, Chile’s second oldest city (founded in 1544). Take a guided city tour of La Serena this morning, then in the early afternoon we travel to the picturesque town of Vicuña to visit a Pisco distillery. We’ll learn about this Chilean liquor and enjoy a private tasting in the cellars of Pisco Elqui. After dinner in Vicuña, enjoy stargazing at El Pangue Observatory for breathtaking southern-sky stargazing through 16- and 25-inch telescopes.

Day 4 (Saturday, Oct. 15): Las Campanas Observatory & GMT Construction
We’ll travel north of La Serena by road to Las Campanas Observatory in the Chilean Andes for a day-long tour of the observatory’s two 6.5-meter optical telescopes. We’ll also check out the construction of the Giant Magellan Telescope (GMT), scheduled to be completed in 2027. The GMT will use seven of the world’s largest mirrors as primary mirror segments, each approximately 8.4 meters (27.6 ft) in diameter and have a higher resolution than the Hubble or Webb space telescopes. (Observatory visits are subject to final confirmation.)
Hotel Costa Real (B, L, D)

Day 5 (Sunday, Oct. 16): Gemini South, SOAR, and Vera Rubin Observatories
Enjoy exclusive visits to the Gemini South Telescope, Southern Observatory for Astro-physical Research (SOAR), and the Vera C. Rubin Observatory — all located on the peak of Cerro Pachón, an 8,900-foot-high mountain in northern Chile. The Gemini Observatory is an 8.1-meter telescope and the adjacent SOAR a 4.1-meter aperture telescope. The Vera C. Rubin Observatory, currently under construction, is an 8-meter-class telescope coupled to a 3.2 gigapixel camera — the largest digital camera ever fabricated for optical astronomy. (Observatory visits are subject to final confirmation.)
Hotel Costa Real (B, L, D)

S&T’s 2017 tour of Chilean observatories included a visit to the 8.1-m Gemini South telescope on Cerro Pachón.

Day 6 (Monday, Oct. 17): Calama & San Pedro de Atacama
This morning we fly north to Calama and transfer to San Pedro de Atacama for a three-night stay. On the way, we will stop at Cordillera de la Sal, the Salt Mountains. Shaped over time by the rain, wind and sun of the Atacama Desert, its final form as we know it today is full of natural sculptures, stratifications, and variegated colors due to its mineral diversity. At sunset, we visit the Moon Valley with its extraordinary landscape caused by the erosion of the Salt Mountains. This evening, we again savor the southern skies at SPACE, home of the largest visual telescope (45-inch aperture) in the Southern Hemisphere.

Day 7 (Tuesday, Oct. 18): El Tatio Geysers & Termas de Puritana Hot Springs
Early this morning we depart on an excursion to El Tatio, the world’s highest major geyser field (elevation: 14,000 feet), to see the great outflow of geysers at sunrise. Afterward, relax in the warm mineral waters of the Termas de Puritana hot springs. Enjoy lunch at La Estaka restaurant before returning to the hotel for an evening lecture. We will have the remainder of the evening at leisure until dinner.

Day 8 (Wednesday, Oct. 19): ALMA Observatory & High-Altitude Lagoons
This morning we visit the Atacama Large Millimeter/submillimeter Array. Situated at an altitude of 16,570 feet (5,050 meters) atop the Chajnantor plateau, ALMA is one of the world’s highest observatories. (Note: To visit this site, you will have to satisfy certain medical requirements. ALMA visit is subject to final confirmation.) In the afternoon, we’ll explore the immense Salar de Atacama with its various species of flamingos. Then we visit the high-plateau lagoons of Miscanti-Miñiques and the Salar de Talar, an evaporated salt lake. Here we’ll see lagoons of beautiful colors and many volcanoes. Look for vicuñas, viscachas, and other wildlife of the area.

Day 10 (Friday, Oct. 21): Very Large Telescope
This morning we’ll drive to the Paranal Observatory, home of the VLT (Very Large Telescope) often described as the world’s largest. Located on top of Cerro Paranal in the Atacama Desert, it has four telescopes of 8.2 meters in aperture. Paranal was chosen because of its excellent atmospheric conditions and its remote location. After touring the facilities, we will transfer to the airport in Antofagasta for a flight to Santiago. (VLT visit is subject to final confirmation.)
Plaza El Bosque (B, L)

Day 11 (Saturday, Oct. 22): Santiago — Tour Ends
Today we explore the beautiful valleys and wineries of Chile’s central region where renowned Chilean wines are produced. Later we’ll gather in the gardens of the historic Viña Santa Rita for a farewell lunch and wine tasting. We return to our hotel and the remainder of our afternoon is unscheduled before driving to the airport for our overnight flights home.

Day 9 (Thursday, Oct. 20): Santiago — Tour Ends
We transfer by bus from San Pedro de Atacama to Calama airport and then fly back to Santiago. While awaiting our international departures that evening, we venture off for a leisurely lunch in a local vineyard before bidding each other farewell and returning home.
