Nanosized chambers capture bits of light for infinite amounts of time.
A new telescope’s unprecedented study of subtle variations in lunar light could finally give Earth-facing satellites a common reference point for their observations.
Weather stations can be used to calibrate and validate albedo measurements from satellites, but they fail to account for variability across landscapes, overestimating how reflective our planet is.
Dense algae populations in the Great Calcite Belt could cause carbon dioxide release from the ocean into the atmosphere.
Injecting aerosols into the atmosphere on purpose could help cool Earth, but new research shows that it could also make the night sky brighter and negatively affect human health.
Computer simulations show that although adding aerosol particles to clouds can make them more reflective, the cooling effect from clouds is largely counterbalanced by a reduction in overall cloud cover.
Nocturnal satellite imagery and other fine-scale data could improve global water resources management.
