May 6, 2024 · “Venus has 100,000 times less water than the Earth, even though it’s basically the same size and mass,” said Michael Chaffin, co-lead author of the study and a research scientist at LASP. In the current study, the researchers used computer models to understand Venus as a gigantic chemistry laboratory, zooming in on the diverse reactions that occur in the planet’s swirling atmosphere.
Surface features of Venus. Global radar map of the surface of Venus. The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the ...
(And, yes, everything in this paragraph applies to Mars as much as it does Venus, despite what "pop sci" would have one think.) But the above paragraph is all beside the point. Venus lost almost all of its water. As the planet warmed (probably due to the warming Sun and an increase in CO2 in the atmosphere), more water evaporated.
Jun 28, 2021 · The narrow red zone (which looks like a thick red line) indicates the water activity of the H 2 SO 4 –H 2 O droplets of Venus’s lower cloud layer (altitude about 40 to 70 km) within the ...

Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. Below the dense, persistent clouds, the surface has volcanoes and deformed mountains.
Primitive atmosphere. But Venus, unlike Earth, has no water. Both planets were initially covered by oceans of magma, which exchanged a lot of volatile substances (including water vapour) with their atmospheres. But Venus is closer to the sun, so it’s possible its magma ocean remained longer than Earth’s, whose water was trapped inside the ...

The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus. Within the Solar System, it is the one nearest to Earth and ...
