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.

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.

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).

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 ...

Absorption spectra When photons of light pass through a gas, the photons with the same energy as the energy gaps in the atoms can be absorbed. This causes an absorption spectra, as shown below.

Explore how satellites measure CO₂ levels and their role in tracking heat absorption in Earth’s atmosphere. This video ...

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 ...

This is comparable to the Fraunhofer lines in the solar spectrum, which give an indication of the atoms in the Sun's atmosphere. In the terahertz spectrum of Venus, an absorption line appears that is ...
