Hot, ocean-covered exoplanets with hydrogen-rich atmospheres could harbour life and may be more common than planets that are Earth-like in size, temperature and atmospheric composition. However, it has so far proven difficult to detect atmospheric signatures from Earth-like planets orbiting Sun-like stars.

Tiny particles of plastic in the atmosphere can affect Earth’s climate, according to Laura Revell at the University of Canterbury in New Zealand and colleagues. Yet even as airborne microplastics become an ever-larger part of the mix of atmospheric aerosols, their radiative influence is still virtually unknown. Altitude matters.
