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.

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 ...

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 ...

In particular, absorption by water in the atmosphere of a giant planet makes the planet appear larger across a specific part of the infrared spectrum compared to wavelengths in the visible spectrum.

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 ...

In both spectra, there is clear evidence for absorption from water and methane whose contributions are indicated with colored contours. During a transit, the planet passes in front of the star, and in ...

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.
