Colonization of Venus
Venus's atmosphere is made mostly out of carbon dioxide, which, after filtering from sulfuric acid, can be used to grow food. Because nitrogen and oxygen are lighter than the carbon-dioxide that makes the atmosphere, breathable-air-filled balloons will float at a height of about . At this height, the temperature is a manageable ; or if we could get higher (see ).
Atmosphere of Venus
The clouds of Venus may be capable of producing lightning, and the Soviet Venera 9 and 10 orbiters obtained optical and electromagnetic evidence of lightning . The European Space Agency's "Venus Express" in 2007 detected whistler waves which were attributed to lightning. Their intermittent appearance indicates a pattern associated with weather activity. According to the whistler observations, the lightning rate is at least half of that on Earth.
