China's first meteorological satellite launched in 1988. It was named Fengyun, which roughly translates to "wind and cloud". Since then, 17 more Fengyun meteorological satellites were launched, with seven still in operation, to monitor Earth's wind, clouds and, more recently, extreme weather events such as hurricanes and wildfires.

Many exoplanets have opaque atmospheres, obscured by clouds or hazes that make it hard for astronomers to characterize their chemical compositions. A new study shows that haze particles produced under different conditions have a wide range of properties that can determine how clear or hazy a planet's atmosphere is likely to be.
