Aug 8, 2024 · Venus lacks our planet's tectonics, including the large, separate areas of planetary crust that grind against each other and help maintain a stable climate here on Earth, and in which the continental land masses are embedded.
May 8, 2024 · Venus experiences temperatures over 800 degrees Fahrenheit and pressures that are more than 75 times that of what we experience on Earth. So what happened to those ancient oceans on our two...
Oct 26, 2023 · Simulations produced by a Brown-led research team offer evidence that Venus once had plate tectonics — a finding that opens the door for the possibility of early life on the planet and insights into its history.

The first probe to fly by Venus was Mariner 2, in 1962. The scorching atmospheric temperatures it found confirmed that the planet had been the victim of a runaway greenhouse effect. But in 1978, NASA’s Pioneer Venus Multiprobe mission found evidence for something that seemed unbelievable: The desiccated, desolate planet may once have had oceans was...
Perhaps the most intriguing instances of Murphy’s law befell both U.S. and Soviet probes. NASA researchers called it the Pioneer Venus 12.5-kilometer anomaly: a strange occurrence that afflicted the four probes in the Pioneer Venus Multiprobe armada as they simultaneously descended through Venus’ complex atmosphere. At an altitude of about 7.5 mile...
Fortunately, answers to this and other mysteries may be at hand in the coming years. Researchers and space agencies are preparing a new wave of Venus missions slated for launch in the early 2030s. These include the European Space Agency’s EnVision orbiter; NASA’s VERITAS orbiter; and NASA’s DAVINCI mission, which will consist of an orbiter and an a...
Mar 2, 2015 · While Venus and Earth have similar sizes and are solar system neighbors, they have evolved very differently. Venus today lacks oceans, appears to lack plate tectonics, and has a massive carbon dioxide atmosphere that creates a greenhouse effect that makes the surface a hot hell.
Aug 6, 2024 · Earth and its "evil twin" Venus are very different today, with the latter lacking plate tectonics. New research indicates Venus may have been much more like our planet than we suspected.
