Lake Coatepeque: A Blue Caldera Seen from the ISS

NASA’s Earth Observatory highlights Lake Coatepeque in El Salvador, a blue caldera lake formed by ancient eruptions. A February 10, 2026 ISS image captures the surrounding volcanic landscape and the caldera’s rim near Santa Ana; while Santa Ana remains active, Coatepeque has had no eruptions in the Holocene. The lake’s sometimes turquoise color is linked to natural mineralization and pigments from microalgae/cyanobacteria. The image, taken with a Nikon Z9, illustrates the Central American Volcanic Arc and the human development around the lake.

"Shining a Light on the Aleutian Islands"

An astronaut aboard the International Space Station captured a stunning photo of the Aleutian Islands illuminated by moonglint, a rare phenomenon caused by the Moon's light reflecting off the water at a specific angle. The Aleutian chain, formed by volcanic eruptions, stretches for about 1,100 miles from the Alaskan Peninsula to Attu Island. The image also showcases the aurora borealis, or northern lights, a colorful display resulting from the interaction between Earth's magnetic field and solar radiation. The photo was taken with a Nikon D5 camera and is part of the ISS Crew Earth Observations Facility.
