An extreme example of the effect is shown by the Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430℃. If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the ...
2.4.1.1 Transmission or Primary Transit As a transiting planet passes between its host star and the observer, the star's flux is diminished by an amount corresponding to the ratio of the stellar and plane- tary areas. The transmission spectrum of the planet represents the star light that ...
