From the iconic image of Earthrise taken by Apollo 8 crew, to the famous Pale Blue Dot image of Earth snapped by Voyager I spacecraft, to state-of-the-art observations of our planet by new satellites such as PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), NASA has given us novel ways to see our home. This Earth Day, […]

Linear Sand Dunes in the Great Sandy Desert
On March 25, 2013, an astronaut aboard the International Space Station took this photo of the Great Sandy Desert in northwest Australia, showcasing linear dunes separated in a roughly regular fashion. When you fly over such dune fields—either in an airplane or the space station—the fire scars stand out. Where thin vegetation has been burned, […]
NASA, NSIDC Scientists Say Arctic Winter Sea Ice at Record Low
Winter sea ice cover in the Arctic was the lowest it’s ever been at its annual peak on March 22, 2025, according to NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder. At 5.53 million square miles (14.33 million square kilometers), the maximum extent fell below the prior […]
NASA Takes to the Air to Study Wildflowers
For many plant species, flowering is biologically synced with the seasons. Scientists are clocking blooms to understand our ever-changing planet. NASA research is revealing there’s more to flowers than meets the human eye. A recent analysis of wildflowers in California shows how aircraft- and space-based instruments can use color to track seasonal flower cycles. The […]
Next-Generation Water Satellite Maps Seafloor From Space
More accurate maps based on data from the SWOT mission can improve underwater navigation and result in greater knowledge of how heat and life move around the world’s ocean. There are better maps of the Moon’s surface than of the bottom of Earth’s ocean. Researchers have been working for decades to change that. As part […]
NASA-ISRO Mission Will Map Farmland From Planting to Harvest
Data from the NISAR satellite will be used to map crop growth, track plant health, and monitor soil moisture — offering detailed, timely information for decision making. When it launches this year, the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite will provide a powerful data stream that could help farmers in the U.S. and around the […]
