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…

Researchers at Tokyo Metropolitan University and collaborating Japanese institutions have used numerical simulations to show that a small X-ray telescope in lunar orbit could map key elements across the entire Moon in just a few years. The work, published in Earth, Planets and Space, points to a practical path for building the first complete chemical…
Researchers at the University of Vienna and Lawrence Berkeley National Laboratory have used machine learning to revisit a mysterious gamma-ray glow near the center of the Milky Way. Their study, published in Physical Review Letters, found that dark matter remains a plausible explanation for the signal known as the Galactic Center Excess. The finding reopens…
A 2026 arXiv study by Slava G. Turyshev argues that the Sun’s own gravity could become the heart of an ultra-powerful space observatory. The proposed solar gravitational lens, or SGL, could someday turn compact stars, black holes and planet-forming disks into detailed images that current telescopes can only hint at. The idea sounds almost impossibly…
