Information from the pioneer spacecraft of the National Aeronautics and Space Administration (NASA) obviously proves the theory that the burning 900-degree Fahrenheit surface temperature of Venus (金星) is due to an atmospheric greenhouse effect caused mainly by a blanket of carbon dioxide. Such a greenhouse effect is created when energy in the form of sunlight easily passes through a planet’s atmosphere, warms is surface, and becomes heat radiation that is then held in by the atmosphere. The orbiting spacecraft has collected Venus’s atmosphere from top to bottom so that NASA’s scientists are able to prove the exact amount of sunlight received at various places in the planet’s atmosphere and on its surface. Measurements of atmosphere, temperature, and radiative heating foresee Venus’s surface temperature very exactly. The planet is closer to the Sun than it is to the Earth, and it has a thin atmosphere like the Earth’s but Venus atmosphere is made up of more than ninety percent carbon dioxide, compared to less than four percent in that of the Earth. Because of its higher percentage of carbon dioxide, Venus’s atmosphere receives much more heat radiation than the Earth’s does. Thus the Venus studies are believed to be important to the understanding of possible bad effects on Earth’s agriculture and sea levels that could result from the long-term use of fuels, which add carbon dioxide to the atmosphere．
