Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
LeoLabs announced that its radar network detected a new unknown object near China’s Shenlong reusable space plane on June 22, 2026. The finding adds another clue to one of the most closely watched spacecraft in low Earth orbit. China’s vehicle has flown multiple long-duration missions, released objects before and shared few public details about its…

ESA/Hubble has released a new Hubble image of NGC 6723, a glittering globular cluster in Sagittarius that sits about 27,000 light-years from Earth. The scene looks delicate, but it belongs to one of the oldest classes of objects in the Milky Way. Inside its crowded glow, astronomers see evidence that this stellar “chandelier” formed through…
Researchers using the NASA/ESA/CSA James Webb Space Telescope report in a Nature study that interstellar comet 3I/ATLAS carries a chemical signature unseen in Solar System comets. The finding suggests that this visitor formed in a cold, distant planetary system that may predate the Sun by billions of years. The comet is only the third confirmed…
A study in APS Open Science tackles one of space exploration’s biggest questions with blunt arithmetic: making Mars broadly habitable would require planet-scale stores of gas, heat, water processing and industrial power. The analysis by Slava G. Turyshev of NASA’s Jet Propulsion Laboratory, California Institute of Technology, lays out why an Earthlike Mars sits far…
