Space telescope observations of the transmission spectrum of the extrasolar planet HAT-P-11b, which is about the same size as Neptune, reveal water vapour absorption at a wavelength of 1.4 ...

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).

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.

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 ...

The measured transit spectrum (top) and eclipse spectrum (bottom) of WASP-80 b from NIRCam’s slitless spectroscopy mode on NASA’s James Webb Space Telescope. In both spectra, there is clear evidence ...

This causes an absorption spectra, ... These 'Fraunhofer' lines are due to the absorption of light of specific frequencies by the gases in the upper atmosphere of the sun. Question.
