This composite shows the total lunar eclipse of 8 September 2025 as seen from Concordia Station in Antarctica. Between 1:00 and 4:00 local time, the crew sequenced the Moon’s passage through Earth’s shadow, from bright silver to deep red and back again.
While around 85% of the world’s population had the chance to view this eclipse, Concordia offered a rare vantage point — perched on Dome C plateau at –80 °C, just a few weeks after the first sunrise since May.
Each year, ESA sponsors a medical doctor to live and work at Concordia through the long Antarctic winter. This year, Dr Nina Purvis from the United Kingdom has joined the DC21 crew – the 21st team to winterover at the station – to study how humans adapt to isolation, darkness and extreme cold. Her research will help prepare for future missions to the Moon and Mars.
