A tiny dye release into Florida's Silver River revealed how groundwater moves through one of America's most productive spring systems—with urgent implications for its ecological future.
Weightlessness doesn't just change how astronauts move—it rewires how plants grow, forcing botanists to rethink agriculture's fundamentals for space.
A poet's final gift connects protected lands into a sprawling wildlife corridor, transforming fragmented hillsides into a landscape where animals can roam unbroken for miles.
Mars has about 97% as much surface area as Earth’s dry land, a geometrical coincidence created by the oceans covering most of the larger planet.
A Florida rancher protected his hard-won land from development by locking it into conservation, proving that ownership and stewardship can be the same thing.
In summer 2024, Cascade Project researchers dyed Michigan's Peter Lake blue with Aquashade to limit light for algae, then added fertiliser; the lake still greened, and the team suspects rain flushed the pigment.
Three XRISM pointings spread over 169 days caught the full swing of motion in the 203-day orbit and measured the iron fluorescence line of gamma Cassiopeiae shifting by 148 kilometres per second between its two quadrature pointings. The star itself, one of the two candidate sources, moved by seven, in the opposite direction.
The red supergiant's stubborn hotspot defies everything astronomers thought they knew about how massive stars churn their surfaces.
Venus resembles Earth in size, but Soviet surface probes could transmit for only 23 to 127 minutes as heat penetrated their protected electronics.
Apophis will pass inside geostationary altitude in 2029 and enter naked-eye range for a vast potential audience, with no risk of impact.
A Saturn encounter shifted 450P/LONEOS inward; Gemini and Webb have now followed its growing dust coma and identified carbon dioxide as the likely driver of its distant activity.
A 2025 spectral and laboratory study points to hydrated ferrihydrite as the chief pigment in Martian dust, tying the planet's colour to its wetter ancient climate.
Juno tracking shows that nine immense north-polar cyclones preserve their rough octagon through competing vorticity forces that act like a spring system.
A 2026 reanalysis finds no localized Hubble signal requiring a Europa plume, weakening the original claim while leaving smaller or intermittent eruptions physically possible.
Magnetic and auroral evidence points to a vast ocean beneath Ganymede, but surface salts do not yet prove a direct connection through its roughly 150-kilometre ice shell.
Europa's moving saltwater should generate a magnetic field, but a 2025 model puts that separate circulation signal below one nanotesla in Jupiter's noisy magnetic environment.
