This vapor formed a disc around the Earth that eventually cooled and clumped together to become the moon. We know this thanks to rigorous studies of meteorites and rock samples, including at the ...

Zare and his colleagues sprayed water vapor into a chamber filled with a mix of gases meant to mimic early Earth's atmosphere, around 2 billion years ago: a noxious blend of ammonia, methane ...

This same effect happens every day on the Earth. Gases within the atmosphere act like glass, trapping the sun's heat. These gases include water vapor, carbon dioxide, methane, nitrous oxide ...

The movements of these vapor tracers can be recorded and studied from the ground ... during the experiment will help gauge ...

The sounding rockets released vapor tracers and pressure sensors at ... study the impact that these geomagnetic light shows have on Earth's upper atmosphere, and the results were gorgeous.
