Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
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 study in Earth and Planetary Science Letters has turned the famous Murchison meteorite into a cautionary tale for the search for ancient life on Mars. Researchers found that two molecules often linked with biology, pristane and phytane, likely entered the meteorite through petroleum-based pollutants in Earth’s atmosphere. The result matters because the same kinds…
A study in The Astrophysical Journal has revisited the famous 2017 GW170817 analysis and produced the most precise measurement yet of the Hubble constant from that single gravitational-wave event. The result gives astronomers a sharper independent check on one of cosmology’s most stubborn questions, how fast the universe is expanding.The new analysis places the Hubble…
A study in Monthly Notices has identified NGTS-38 b, a rare giant world that takes about 180 days to circle its star. Led by scientists at Queen’s University Belfast, the international team found a planet about 8% wider than Jupiter and nearly five times as massive. The planet, formally cataloged as TIC-65910228 b and also…
