San Francisco’s Patchwork Streets

An astronaut aboard the International Space Station took this picture of downtown San Francisco and nearby communities on May 27, 2026. The image captures two of the region’s iconic bridges. The Golden Gate Bridge connects the northern San Francisco Peninsula with Marin County to the north, while the San Francisco-Oakland Bay Bridge spans the bay toward […]

NASA, USGS Scientists Go Rock Hounding in California’s High Desert

Equipped with rock picks and hand lenses, a team of geoscientists deployed to the Mojave Desert recently to investigate a tantalizing “fingerprint” detected by a NASA sensor. Their target: a cache of topaz hiding in plain sight. The geologists weren’t searching for gem-grade treasure. Rather, the presence of topaz could hint at a more valuable […]

NASA Satellites Uncover Large-Scale Ocean Nutrient Stress 

As Earth’s oceans warm, microscopic marine organisms are experiencing increasing stress due to a lack of vital nutrients. A new study combining NASA satellite observations, ocean surveys, and genetic testing on marine microorganisms suggests that warming ocean waters are limiting nutrient availability across much of the global ocean, with the potential to reshape marine ecosystems.  The research, published June 5 […]

NASA-European Sea Level Mission Homes in on El Niño

Sea level data from a satellite launched by NASA and European partners shows that a swell of warm water hundreds of miles wide has arrived in the Pacific Ocean off the coast of South America, a sign that El Niño will likely emerge later in the year. Because water expands as it warms, a rise […]

Chennai City Lights

Chennai, on India’s southern coast along the Bay of Bengal and with a metropolitan population of about 8.7 million, shines with white LED streetlights in this photograph taken at approximately 9:13 p.m. local time on May 2, 2026, from the International Space Station. Earth observations from the space station let us see how our planet […]

NASA-developed AI Could Help Track Harmful Algae

NASA scientists have developed an artificial intelligence tool to take on a longstanding challenge in ocean waters. In a study recently published in AGU Earth and Space Science, researchers reported the tool was able to fuse data from multiple satellites and detect harmful algal blooms that occurred in western Florida and Southern California. Severe blooms […]
