A flash of lightning shines brighter than the lights of nearby cities in this Oct. 29, 2024, image taken by astronaut Don Pettit while aboard the International Space Station. At the time of this photograph, little to no moonlight illuminated the scene. This allows astronauts to see and photograph a variety of light sources with […]

NASA Data Helps Map Tiny Plankton That Feed Giant Right Whales
In the waters off New England, one of Earth’s rarest mammals swims slowly, mouth agape. The North Atlantic right whale filters clouds of tiny reddish zooplankton — called Calanus finmarchicus — from the sea. These zooplankton, no bigger than grains of rice, are the whale’s lifeline. Only about 370 of these massive creatures remain. For […]
NASA Airborne Sensor’s Wildfire Data Helps Firefighters Take Action
Data from the AVIRIS-3 sensor was recently used to create detailed fire maps in minutes, enabling firefighters in Alabama to limit the spread of wildfires and save buildings. A NASA sensor recently brought a new approach to battling wildfire, providing real-time data that helped firefighters in the field contain a blaze in Alabama. Called AVIRIS-3, […]
Sunshine on Earth
The Sun’s glint beams off a partly cloudy Atlantic Ocean just after sunrise as the International Space Station orbited 263 miles above on March 5, 2025. The space station serves as a unique platform for observing Earth with both hands-on and automated equipment. Station crew members have produced hundreds of thousands of images, recording phenomena […]
Celebrating Earth as Only NASA Can
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 […]
