ALT Map of the Arctic with colors indicating how the sea ice melting season has changed from 2000 to 2009. Red indicates areas where the season grew longer. Blue indicates where it grew shorter. The map is mostly dark red, indicating an increase of about 5 days or more. Closer to the pole, the melting season has changed less dramatically. Credit: NASA
ALT Map of the Arctic with colors indicating how the sea ice melting season has changed from 2010 to 2023. Red indicates areas where the season grew longer. Blue indicates where it grew shorter. The map shows a mix of lighter red and blue, indicating smaller changes of only a few days. Credit: NASA

ALT NASA satellite image of fire smoke covering much of Indonesia and Malaysia on September 1, 2026. The plumes are gray, with only some areas of green and brown land visible through the smoke. Red dots have been added to show where the MODIS instrument detected fires. The dots are primarily on the western and southern parts of Indonesia and often cluster together. Credit: NASA

ALT A full disk image of Earth, as seen from the Orion capsule. The image shows Earth at nighttime, using a slow camera shutter speed to bring out details that would otherwise be shrouded in darkness. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in places from reflected light. From about 8 to 9 o’clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o’clock spot, aurora glow in a thin green glow, just barely separated from the planet’s surface. Earth is set against the black of space. Credit: NASA
ALT A map shows the path of totality of the solar eclipse on August 12, 2026, arcing across Greenland, Iceland, the North Atlantic, and Spain.
ALT A global map shows where the August 12, 2026 total solar eclipse will be visible. A red band shows the path of totality. It passes over Greenland, Iceland, northern Russia, Spain, and part of Portugal. Yellow lines indicate percentages of the partial solar eclipse, which will be visible in much of the Northern Hemisphere. Credit: NASA
ALT Map showing chlorophyll concentrations in the Pacific Ocean during an El Niño in June 2026. Green areas indicate more chlorophyll and blue areas indicate less. There is a band of green along the equator, except off the eastern coast of Australia. An arrow points to this area of low chlorophyll. Other than the equator and along coastlines, the ocean is mostly shown in blue.
