Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
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 Space Weather proposes a bold planetary defense concept for one of modern civilization’s largest natural hazards. The system, called StormWall, would use spacecraft to release material near Earth before a severe solar storm arrives. The idea comes from researchers including Brian Walsh of Boston University and collaborators at the University of Michigan.…
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…
