题目内容
Lucien Rudaux, a French artist, was the first to combine his artistic talents with his knowledge of astronomy. His paintings show a mixture of skilled observations, brilliant imagination, and painstaking attention to details. As a result, many of his works have come surprisingly to close to actual conditions on distant planets. His painting of Mars included moonlike craters that were first photographed by the Mariner 4 probe in 1965. His 1930 painting of a dust storm looks remarkably like a photograph of a storm taken by Orbiter 2 in 1976.
The artist-astronomers, including Rudaux, stimulated interest in outer space by painting what eventually turned out to be precise portraits of the planets.
