These detections are often made using spectroscopy, which can identify water vapor by its unique absorption lines in the ...

Their atmospheric spectra are just too similar when you're trying to hunt for water vapor. In a recent preprint paper, astronomers note that they've found a different signature gas that might be a ...

Researchers are using basalt spectra to study exoplanets and search for water with the James Webb Space Telescope. By studying chemical processes in the Earth's hot mantle, Cornell scientists are ...
