When you look at photographs of Earth from space, the planet looks like a blue marble, with patterns of clouds lying on the surface of the marble. It seems as if Earth's atmosphere is incredibly thin, ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...

Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth ...

Researchers have created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. Using a new data-assimilation system called JAGUAR-DAS, ...

The Moon may preserve a chemical record of Earth’s ancient atmosphere, and those same materials could one day support future lunar missions.
