- Did Venus ever host life? Big questions are often asked when thinking about other planets: Is there life? WAS there ever life? If so, what sort of life?
- How did Venus and Earth come to be so different? Venus and Earth are similar in size and density, so hypothetically, these planets could be very similar.
- How did Venus form? Even this seemingly basic question about the origin of Venus is still a mystery. “It’s amazing to me that we don’t know whether Venus formed from the same early solar system materials as did Earth and Mars,” says Getty.
- What is the atmospheric composition at Venus? The atmospheric composition of Venus is an important piece of the context we are seeking as we aim to better evaluate Venus’ potential habitability over time.
Sep 26, 2023 · Venus is remarkably similar to Earth in many ways, but saying its surface is unsuitable for life is a drastic understatement. In this episode of Dead Planets Society, our hosts attempt to fix...
Apr 20, 2022 · Venus takes 243 Earth days to rotate one time, but its atmosphere circulates the planet every four days. Extremely fast winds cause the atmosphere to drag along the surface of the planet as it circulates, slowing its rotation while also loosening the grip of the sun’s gravity.
6 days ago · As the brightest planet in the night sky, Venus allured ancient astronomers into naming the world after the Roman mythological goddess of love and beauty. This now seems an ironic choice, but the contrast between distant observation and surface conditions produces an apt juxtaposition for exoplanets.

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...
Oct 14, 2019 · These very important discoveries – telling us that Venus is very much alive – are some of the key reasons why need to go back there. Coupled with the current work in understanding early Earth and its processes, they make us realise that we need to understand more about the planet, because it is intricately linked with our future on Earth.

Mar 20, 2018 · Despite its appeal, the second planet from the sun is one of the hardest places in the solar system to get to know. That’s partly because modern Venus is famously hellish. Temperatures are hot enough to melt lead. Choking clouds of sulfuric acid swirl through its atmosphere.
