Circular Star Trails
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 microgravity lab hosting technology, demonstrations, and scientific investigations from…

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 after high-energy radiation exposure; developing novel readout modes to mitigate radiation-induced damage; and simulating a near-infrared CMOS pixel…

Tech From NASA’s Hurricane-hunting TROPICS Flies on Commercial Satellites
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 was originally developed for NASA’s TROPICS (short…

NASA Astronaut Megan McArthur Retires
NASA astronaut Megan McArthur has retired, concluding a career spanning more than two decades. A veteran of two spaceflights, McArthur logged 213 days in space, including being the first woman to pilot a SpaceX Dragon spacecraft and the last person to “touch” the Hubble Space Telescope with the space shuttle’s robotic arm. McArthur launched as pilot of NASA’s SpaceX Crew-2…

Landsat 9 Sees Buccaneer Archipelago
The Operational Land Imager on Landsat 9 captured this image of Buccaneer Archipelago on June 11, 2025. The scene encapsulates the striking interactions between land and water in the area where King Sound opens to the Indian Ocean. The powerful tidal currents stir up sediment in shallow areas, producing the beautiful turquoise swirls visible in this image. This power, however, can be hazardous to seafarers…

Hubble Homes in on Galaxy’s Star Formation
This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the spiral galaxy Messier 96 is the brightest of the galaxies in its group. The gravitational pull of its galactic neighbors may be responsible for Messier 96’s uneven distribution of gas…

NASA Invites Media to Learn About New Missions to Map Sun’s Influence
NASA will hold a media teleconference at 12 p.m. EDT on Thursday, Sept. 4, to discuss the agency’s upcoming Sun and space weather missions, IMAP (Interstellar Mapping and Acceleration Probe) and Carruthers Geocorona Observatory. The two missions are targeting launch on the same rocket no earlier than Tuesday, Sept. 23. The IMAP mission will map the boundaries of our heliosphere, the vast…

NASA Marsquake Data Reveals Lumpy Nature of Red Planet’s Interior
Rocky material that impacted Mars lies scattered in giant lumps throughout the planet’s mantle, offering clues about Mars’ interior and its ancient past. What appear to be fragments from the aftermath of massive impacts on Mars that occurred 4.5 billion years ago have been detected deep below the planet’s surface. The discovery was made thanks to NASA’s now-retired InSight lander,…

NASA Scientists Help Maryland County Plan to Beat Summer Heat Risks
Thousands of Americans are impacted each summer by excessive heat and humidity, some suffering from heat-related illnesses when the body can’t cool itself down. Data from NASA satellites could help local governments reduce the sweltering risks, thanks to a collaboration between NASA scientists and officials in Prince George’s County, Maryland. The effort demonstrates how local officials in other communities could…

NASA, International Astronauts to Address Students from New York
NASA astronaut Jonny Kim and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui will connect with students in New York as they answer prerecorded science, technology, engineering, and mathematics (STEM) questions aboard the International Space Station. The Earth-to-space call will begin at 9:20 a.m. EDT on Friday, Sept. 5, and will stream live on the agency’s Learn With NASA YouTube channel. Media interested…
