As the International Space Station (ISS) was traveling over India towards the day-night terminator, an astronaut shot this photograph of Earth’s third-highest summit, Kangchenjunga, and its surrounding peaks warmly lit by the setting Sun. With the Sun low in the sky, the light was passing through more atmosphere, which scatters it towards the red end of the visible spectrum.
Kangchenjunga rises more than 8500 meters (28,000 feet) above sea level. It stands in eastern Nepal near the border with India and about 120 kilometers (75 miles) east-southeast of Mount Everest. The apex of Kangchenjunga is surrounded by valley glaciers, some of which (like Yalung) are discernable in the shadows of this image. Just out of reach of the Sun’s rays, a deck of low-lying clouds lingers over the valley floors.
Thirteen other mountain peaks on Earth rise higher than 8000 meters (26,000 feet). These are known by mountaineers and climbers as the “eight-thousanders.” Oblique views such as this one give the dauntingly dangerous terrain a three-dimensional appearance and depth.

Astronaut photograph ISS061-E-92131 was acquired on December 16, 2019, with a Nikon D5 digital camera using a 500 millimeter lens and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 61 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by Andrew Britton, Jacobs, JETS Contract at NASA-JSC.
