NASA astronauts Zena Cardman and Jonny Kim are pictured working in the Kibo laboratory module’s Life Science Glovebox processing bone stem cell samples to understand space-caused bone loss.NASA Bones and transistors were the main research topics aboard the International Space Station on Tuesday to explore how microgravity affects the human body and advanced technology. Also, [...]
Photo of the Day The Horsehead Nebula is one of the most famous nebulae on the sky. It is visible as the dark indentation to the orange emission nebula at the far right of the featured picture. The horse-head feature is dark because it is really an opaque dust cloud that lies in front [...]

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 [...]
Photo of the Day What created this unusual planetary nebula? Dubbed the Pillow Nebula and the Flying Carpet Nebula, NGC 7027 is one of the smallest, brightest, and most unusually shaped planetary nebulas known. Given its expansion rate, NGC 7027 first started expanding, as visible from Earth, about 600 years ago. For much of [...]
Expedition 73 Flight Engineers (clockwise from top) Zena Cardman, Jonny Kim, and Mike Fincke, all three NASA astronauts, and Kimita Yui from JAXA (Japan Aerospace Exploration Agency) gather together inside the Kibo laboratory module prior to a conference with officials on the ground.NASA Bone and brain research wrapped up the week aboard the International Space [...]
Photo of the Day The diffuse hydrogen-alpha glow of emission region Sh2-27 fills this cosmic scene. The field of view spans nearly 3 degrees across the nebula-rich constellation Ophiuchus toward the central Milky Way. A Dark Veil of wispy interstellar dust clouds draped across the foreground is chiefly identified as LDN 234 and LDN [...]
