An unexpected winter surprise has transformed the high-altitude landscapes of Chile, as a rare frost brings a spectacular blanket of snow to the Southern Astrophysical Research (SOAR) Telescope.

What Makes SOAR a Stellar Marvel?

Standing proud at 13.4 feet (4.1 meters), the SOAR Telescope is a vital asset for astronomers in the Southern Hemisphere. It specializes in both optical and near-infrared astronomy, allowing researchers to delve deep into the mysteries of the cosmos. Launched in 1987 by the University of North Carolina at Chapel Hill, this telescope operates under an international consortium that includes prestigious partners from Brazil, Chile, Michigan State University, and the University of North Carolina.

Where the Magic Happens

Nestled atop Cerro Pachón in the majestic Andes mountain range, the SOAR Telescope boasts an ideal location for stargazing. Just a stone's throw away, the Gemini South telescope also captures the wonders of the universe in visible and infrared wavelengths.

A Rare Snowfall in the Driest Place on Earth

In an extraordinary twist of nature, a rare winter storm recently swept across the Atacama Desert, blanketing even the driest place on Earth in fresh snow. While this winter wonderland created breathtaking views, the impact varied significantly among the nearby observatories.

For the SOAR Telescope, the snow was a soft touch, giving the observatory a picturesque appearance and inspiring stunning photographic opportunities. However, down on the Chajnantor Plateau, the Atacama Large Millimeter/submillimeter Array (ALMA) faced harsher realities, with severe weather forcing it to suspend all scientific operations since June 26, 2025. ALMA's reliance on delicate electronic equipment made it especially vulnerable to extreme weather fluctuations, emphasizing the challenges posed by such brief but intense storms.
