Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
Six volunteers have been living behind a sealed door in Cologne, Germany, since April 23, 2026 and the 100-day isolation phase is now nearing its scheduled August 7 end as researchers study a problem that future astronauts cannot avoid: how people hold up when the crew is small, privacy is scarce and help from Earth…

A Caltech study in The Astrophysical Journal Letters describes an astronomical mystery with a startling possible solution. A massive star may have exploded as a supernova and produced two unusually small neutron stars. Those dense remnants could have collided hours later, creating a second blast inside the debris of the first. The candidate event, called…
A study in Science Advances has identified a strange class of cosmic dust that may come from a near-Earth asteroid unlike anything represented in meteorite collections. The particles, found in Antarctic samples and on urban rooftops, carry chemical fingerprints that point to a sulfur-rich parent body scientists have yet to recover as a larger meteorite.…
A study in The Journal of the Astronautical Sciences has uncovered some of the faintest debris ever detected in geosynchronous orbit. Led by researchers at the University of Warwick, the international team found tiny fragments near the orbital region used by some of Earth’s most important satellites. The objects are small, faint and easy to…
