When Idaho's highway engineers faced a mountain of recycled glass, they didn't haul it to a landfill—they paved over it, burying 300 tons beneath a major road in an experiment that raises questions about infrastructure durability and waste reuse.
A 2025 model links Venus’s 6,800-kilometre canali to rare, low-viscosity carbonatite lava and a potentially late addition of much of the planet’s carbon dioxide atmosphere.
Hydrogen predates the stars, while generations of stellar fusion, supernovae and galactic recycling supplied the heavier elements now arranged into living bodies.
FAST and DESI data show that the universe retained most of its neutral atomic hydrogen while its star-formation rate fell by more than half, shifting attention to gas phase conversion and regulation.
AI data centres can finance new solar farms while also making gas plants run more often. The outcome depends on timing, location, storage, grid queues and how clean energy is counted.
Adding temperature-dependent rock strength to a canonical giant-impact calculation changed how Theia deformed—and in one run left a coherent Moon-sized satellite within hours.
An accidental aerosol capture during Pioneer Venus's descent may have recorded hydrated salts and far more bound water than the standard sulphuric-acid cloud model allows.
Seasonal changes in Mars's gravity imply that the mantle beneath its ancient southern highlands is hundreds of degrees warmer than the north, but three origin stories remain.
Kepler-36b and its Neptune-sized neighbour pass within about 1.9 million kilometres, creating a giant sky view and a powerful, changing tide across the rocky planet.
Cecilia Payne's 1925 thesis found that hydrogen and helium dominate stellar atmospheres, then retreated from the result after Henry Norris Russell called it impossible.
A simulated Population III supernova remnant produced enough concentrated solids for rocky-world precursors at cosmic dawn, but the calculation stopped well before a finished planet.
Mars winter can turn atmospheric carbon dioxide into snow and frost, shifting trillions of tonnes of gas into a polar cap and changing pressure across the planet.
Organic grain analogues clung to a nitrogen-filled tumbler after becoming charged, but later tholin tests show why the result cannot yet be assumed to describe Titan's real dunes.
A 13,000-square-mile swath of Appalachia has surrendered its airwaves so one telescope can listen to the cosmos.
N₂ dominates Earth’s air yet lacks the strong infrared bands used to identify many gases. Its best remote clue is a pressure-sensitive absorption near 4.15 micrometres, created briefly when nitrogen molecules collide.
Water frost only about 10 micrometres thick appears for a few cold-season morning hours across four giant Martian volcanoes. Its vast coverage may exchange approximately 150,000 tonnes of water with the atmosphere each day.
