The composition and great density of 'hot Saturn' exoplanet Smertrios are a challenge to planet formation models that the ...

The absorption spectrum is consistent with both a dense “steam” atmosphere made up of 70 percent water, as well as a cloudy hydrogen atmosphere where the clouds would hide the absorption spectra.

Note to students that this graphic represents stellar absorption spectra (in which specific wavelengths of starlight have been absorbed by gases in the sun's lower atmosphere or Earth's atmosphere).

An international team of scientists recently measured the spectrum of the atmosphere of a rare hot Neptune exoplanet, whose discovery by NASA's Transiting Exoplanet Survey Satellite (TESS) was ...

The Archean Earth spectrum represents a scientific model of Earth's atmosphere based on what is known about this time in Earth's history and what is understood about modern planetary atmospheres.

Artist's impression of the exoplanet τ Boötis b, a huge planet orbiting a nearby star. Astronomers have used a measurement of the planet's atmosphere to determine its mass and orbit.

He obtained the photographic spectra of N, O, CO2, CO, aqueous vapour and hydrogen by means of an ingeniously constructed spectroscope, from which he could exhaust all the gas except that on which ...

Measurements of the optical absorption spectrum. An atmospheric-pressure plasma in argon was formed at the surface of an aqueous solution by biasing a metal capillary electrode suspended over the ...
