Vor 5 Tagen · Venus is choked by toxic carbon dioxide clouds that rain sulfuric acid. The surface of Venus, sculpted by volcanism, has been subjected to a runaway greenhouse effect that now keeps temperatures at an average scorching 464 degrees Celsius (867 Fahrenheit). But the missing water remained a problem.
Vor 15 Stunden · Faster hydrogen loss today via DR means that less time is required overall to remove the remaining water from Venus. This means that if oceans were ever present on early Venus, they could have been present for longer than scientists thought before water loss through hydrodynamic escape and DR started. This would provide more time for possible ...
Vor 5 Tagen · The ultraviolet radiation from the sunlight breaks down both the carbon dioxide and the water into electrically charged atoms. The “free” atoms then form HCO+, completing the dissociative ...
Vor 3 Tagen · It takes 224.7 Earth days for Venus to complete an orbit around the Sun, and a Venusian solar year is just under two Venusian days long. The orbits of Venus and Earth are the closest between any two Solar System planets, approaching each other in synodic periods of 1.6 years.

Vor 5 Tagen · 08.05.2024. Einst sah die Venus aus wie die Erde. Inzwischen gibt es dort kein Wasser mehr. Forscher*innen haben eine neue Theorie dazu. Die Venus gilt mit einer dichten Atmosphäre und...
Vor 5 Tagen · As faster water loss means less time is needed to boil away the planet's water reservoir, scientists say Venus may have harbored oceans — and potentially habitable conditions — for longer than...
Vor 5 Tagen · As an illustration, if you spread out all the water on Earth, it would form a layer 1.9 miles (three km) deep. But on Venus, that layer would only be 1.2 inches (three cm) deep. In fact,...
