The period of its orbit—that is, the length of the Venusian year—is 224.7 Earth days. Observation of the phases of Venus was inconsistent with this view but was consistent with the Polish astronomer Nicolaus Copernicus’s idea that the solar system is centred on the Sun. Image credit: B. Campbell, Smithsonian, et al., NRAO/AUI/NSF, Arecibo High-resolution radar images of Venus were first obtained by Arecibo in 1988 and most recently by Arecibo and GBT in 2012, with additional coverage in the early 2000s by Lynn Carter of NASAâs Goddard Spaceflight Center in Greenbelt, Md. Jan. 31, 2019: A Japanese research group has identified a giant streak structure among the clouds covering Venus based on observation from the spacecraft Akatsuki.The team also revealed the origins of this structure using large-scale climate simulations. Målning. A planet’s rotation generally causes a bulging at the equator and a slight flattening at the poles, but Venus’s very slow spin allows it to maintain its highly spherical shape. This composite of telescopic images illustrates the steady changes for the inner planet, seen in the west as the evening star, as Venus grows larger but narrows to a thin crescent from December 20, 2016 through March 10. And in the Disney animated film The Princess and the Frog, Ray the firefly falls in love with Venus, "the evening star," as he has mistaken it for another firefly. Its obscured appearance results from the surface of the planet being hidden from sight by a continuous and permanent cover of clouds. Added colour in the image emulates Venus's yellow-white appearance to the eye. Venus is proving to be an exciting place of discovery, though it had not been a significant part of the search for life because of its extreme temperatures, atmospheric composition and other factors. Venus is unusual because it spins the opposite direction of Earth and most other planets. One of scientists’ major goals in studying Venus is to understand how its harsh conditions came about, which may hold important lessons about the causes of environmental change on Earth.

On Dec. 14, 1962, NASA's Mariner 2 spacecraft sailed close to the shrouded planet Venus, marking the first time any spacecraft had ever successfully made a close-up study of another planet. Solar system. Early telescopic observations of the planet revealed a perpetual veil of clouds, suggestive of a substantial atmosphere and leading to popular speculation that Venus was a warm, wet world, perhaps similar to Earth during its prehistoric age of swampy carboniferous forests and abundant life. These are not identical twins, however – there are radical differences between the two worlds. When the solar system settled into its current layout about 4.5 billion years ago, Venus formed when gravity pulled swirling gas and dust together to form the second planet from the Sun.
