NASA/Nichole Ayers On July 26, 2025, NASA astronaut Nichole Ayers took this long-exposure photograph – taken over 31 minutes from a window inside the International Space Station’s Kibo laboratory module – capturing the circular arcs of star trails. In its third decade of continuous human presence, the space station has a far-reaching impact as a [...]
Advancing Single-Photon Sensing Image Sensors to Enable the Search for Life Beyond Earth A NASA-sponsored team is advancing single-photon sensing Complementary Metal-Oxide-Semiconductor (CMOS) detector technology that will enable future NASA astrophysics space missions to search for life on other planets. As part of their detector maturation program, the team is characterizing sensors before, during, and [...]
NASA science and American industry have worked hand-in-hand for more than 60 years, transforming novel technologies created with NASA research into commercial products like cochlear implants, memory-foam mattresses, and more. Now, a NASA-funded device for probing the interior of storm systems has been made a key component of commercial weather satellites. The novel atmospheric sounder [...]

The human research study seeks to improve treatments for kidney stones and osteoporosis NASA astronaut Megan McArthur has retired, concluding a career spanning more than two decades. A [...]
In the sparsely populated Kimberley region of Western Australia, jagged landforms reach like fingers into the turquoise-blue ocean waters. Along the coastline north of Derby, they used to reach even farther. But rising sea levels submerged part of the coastal landscape, giving rise to hundreds of islands and low-lying reefs that compose the Buccaneer Archipelago.NASA/Michala [...]

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Scientists believe giant impacts — like the one depicted in this artist’s concept — occurred on Mars 4.5 billion years ago, injecting debris from the impact deep into the planet’s mantle. NASA’s InSight lander detected this debris before the mission’s end in 2022.NASA/JPL-Caltech Rocky [...]
