Last week, Artemis 2 astronauts witnessed a total solar eclipse from space, as the Orion spacecraft spent nearly an hour in the moon's shadow. But, as a remote team at the French-Italian Concordia Research Station recently experienced, you don't need to travel beyond the moon to see a truly private eclipse.
The Concordia Research Station is the most remote research base in Antarctica, located 750 miles (1207 kilometers) inland at an altitude of 10,600 feet (3,230 meters). The small crew stationed there endures average winter temperatures of -58 degrees Fahrenheit (-50 degrees Celsius), and four months each without seeing the sun rise above the horizon. This region is also one of the driest on Earth — part of Antarctica's vast polar desert.
On Feb. 17 2026, the Concordia team witnessed something likely seen nowhere else on Earth — an annular solar eclipse.
Annular solar eclipses, often called "ring-of-fire" eclipses, occur when the moon passes in front of the sun at a point in its orbit where it appears slightly smaller in the sky. Instead of completely blocking the sun, the moon leaves a bright ring of sunlight visible around its edges.
Unlike total solar eclipses, which reveal the sun's faint outer atmosphere, annular eclipses are still a form of partial eclipse and require proper eye protection to view safely.
The path of annularity, where the ring-of-fire effect is visible, crossed Antarctica during the Feb. 17 event. It passed over just two inhabited locations: Concordia Research Station and Mirny Station, a Russian base.
But clouds obscured the view over Mirny.
That left a small group at Concordia as the only people on Earth to witness this eclipse in its full annular form. I spoke to one of them, Andrea Traverso, about the experience.
Traverso arrived at Concordia in November 2025 and will remain there until November 2026. He oversees scientific experiments and monitoring systems across the station, including studies of geomagnetism, seismology and meteorology, as well as investigations into how the upper atmosphere interacts with solar wind.
This marks his third "winterover" at the base, following previous stays in 2019 and 2020.
When I asked where he observed the eclipse from, Traverso described the station's layout — two cylindrical towers with windows facing multiple directions.
During the event, he positioned himself at "a window in perfect alignment with the eclipse," which offered "many possibilities from a photographic point of view".
Sheltered from the extreme cold, he simply opened the window to avoid reflections from the glass and began taking photos.
The result was remarkable.
Traverso captured a striking image of the ring-of-fire eclipse that was later shared widely by the European Space Agency.
But it wasn't until after the event that the full significance of the event came clear.
Traverso contacted other Antarctic stations to ask about their weather conditions. Many, including Mirny, had been clouded out.
No one else had seen it.
It was the he said, that he "became aware of the uniqueness of my observation."
In a Facebook post translated from Italian, Traverso wrote:
"Yesterday night's eclipse, photographed by me, visible in this form exclusively from the Italian-French base Concordia in Antarctica. My wonderful white lady also gave me this spectacle that only me and my 11 companions could enjoy live."
Surprisingly, the team had not prepared in advance for the event.
"I wasn't aware in advance about the eclipse and the possibility of observing it from Concordia," Traverso said.
Capturing an annular eclipse requires solar filters — similar to eclipse glasses — to safely reduce the sun's brightness. But none had been specifically set aside for the event.
Instead, Traverso improvised.
He found some sheets of mylar film stored at the base, which had previously been used for solar observations a long time ago and used cardboard and glue to build a makeshift filter for his camera lens.
"The solution proved to be effective," Traverso said.
Given that his image remains the only known photograph of the eclipse from Earth, it's hard to argue otherwise.
