A Pair of Hearts

One frozen, one salty, and hemispheres apart, two very different lakes share a Valentine shape.

NASA Earth Observatory images by Wanmei Liang, using Landsat data from the U.S. Geological Survey. Astronaut photograph ISS070-E-76257 was acquired on January 16, 2024, with a Nikon D5 digital camera using a focal length of 500 millimeters. It was 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 70 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. Story by Lindsey Doermann.
