Venus : the planet second in order from the sun — Webster See also OneLook

Encyclopedia

Venus is the third smallest planet in the Solar System, it is a terrestrial planet, and it is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet’s surface is about 92 times the sea level pressure of Earth, or roughly the pressure at 900 m (3,000 ft) underwater on Earth. Even though Mercury is closer to the Sun, Venus has the hottest surface in the Solar System, with a mean temperature of 737 K (464 °C; 867 °F). Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from Earth in light. It may have had water oceans in the past, but after these evaporated the temperature rose under a runaway greenhouse effect. Because of the lethal surface conditions, the planet is sometimes referred to as Earth’s “evil twin.” — Wikipedia

History

Magellan was a 1,035-kilogram (2,282 lb) robotic space probe launched by NASA of the United States, on May 4, 1989, to map the surface of Venus by using synthetic-aperture radar and to measure the planetary gravitational field. It was the first interplanetary mission to be launched from the Space Shuttle, the first one to use the Inertial Upper Stage booster, and the first spacecraft to test aerobraking as a method for circularizing its orbit. — Wikipedia

Evidence that Venus is volcanically active
on March 15, 2023 at 6:39 pm
Venus appears to have volcanic activity, according to a new research paper that offers strong evidence to answer the lingering question about whether Earth's sister planet currently has eruptions and lava flows.
No signs (yet) of life on Venus
on June 14, 2022 at 4:26 pm
The unusual behavior of sulphur in Venus' atmosphere cannot be explained by an 'aerial' form of extra-terrestrial life, according to a new study.
NASA's Davinci mission to take the plunge through...
on June 3, 2022 at 2:01 pm
NASA scientists and engineers give new details about the Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.
Why Venus rotates, slowly, despite sun's powerful...
on April 20, 2022 at 1:21 pm
If not for the soupy, fast-moving atmosphere on Venus, Earth's sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon always faces Earth.
Could acid-neutralizing life-forms make habitable...
on December 21, 2021 at 12:06 am
A new study supports the longstanding idea that if life exists, it might make a home in Venus' clouds. The study's authors identified a chemical pathway by which life could neutralize Venus' acidic environment, creating a self-sustaining, habitable pocket in the clouds.
