A new study suggests that many exoplanets – worlds orbiting distant stars – might have an overabundance of toxic gases in their atmospheres. If so, that would make the evolution of complex life forms more difficult. Source: https://earthsky.org/space/toxic-gases-habitable-zones-complex-life-exoplanets…
