...about the planet Venus. At the time, many scientists still regarded Venus as a kind of sister planet of the earth with a benign climate. But radio emissions from the planet were hinting at puzzlingly high temperatures. Sagan pointed out that a Venusian atmosphere of carbon dioxide and water vapor would trap solar heat, create a "greenhouse effect" and raise surface temperatures far above those of the earth. His prediction was soon confirmed by Soviet landers. The planet's surface temperature proved to be about 480° C (900° F), high enough to melt lead...

Nerve gases are usually stored as liquid and when released as a vapor or spray of droplets can enter the body by inhalation or by absorption through the skin. The gases work by blocking neurotransmitters, disrupting the central nervous system, inducing vomiting, convulsions and paralysis and finally death from respiratory failure and asphyxia. Exposure 0.4-1 milligram of gas kills within a few minutes. When released in high density nerve gases can persist as an airborne hazard for days or weeks...
