The clouds of Venus join the shortlist for potential signs of life in our solar system Some point to Venus as a sign of our planet's future if human behavior doesn't change. These questions are especially relevant for Earth, where human-produced greenhouse gases continue to build up in the atmosphere. If our twin planet continues to belch gases into the air through its peaks, that would argue for a slow shift in the atmosphere rather than a single cataclysm. Low-resolution radar images of the surface have shown evidence for recent explosive volcanism, within the past 100 million years. Ongoing observations have also revealed that Venus is anything but inactive. Close behind is the question of whether the Venusian atmosphere changed dramatically in a single catastrophe or whether it was a slow change over time. That's a question that still plagues Venus researchers as they seek to determine the conditions that lead to habitability and those that lead to an overheated catastrophe. Both planets appear to have the same origins: rocky worlds large enough to hold onto their atmospheres with initial conditions ripe to collect water on the surface. The conditions that once led scientists to suspect Venus could be an Earth-like world hadn't changed. 'However, we're realizing now that it is only the beginning.' 'Many people assumed Venus was a 'solved problem,' where a runaway greenhouse scenario had run amuck and that was the end of the story,' Kane said. The planet's thick atmosphere worked as a blanket to trap heat, raising the temperatures to unbearable extremes. 'Although the realization during the '60s regarding the hellish conditions of Venus caused many to believe that Venus has nothing to do with habitability, we have since changed our perspective to understand that Venus has everything to do with habitability,' Kane said.Дuring the initial phases of exploration, scientists quickly realized that Venus was suffering a severe case of the greenhouse effect. The results may help to resolve questions about the evolution of life. The myriad observations, along with advances made in understanding how planets evolve, have presented a slowly changing picture of Venus. Meanwhile, missions across the solar system regularly use Venus as a gravitational boost to distant worlds, taking a few brief observations on their way past. In 2015, Japan's Akatsuki mission began a probe of the Venusian atmosphere that continues today. In 1990, NASA's Magellan mission mapped the surface of the planet and the European Space Agency's Venus Express orbited the world for eight long years, studying its atmosphere. NASA's Viking and Pioneer missions blew by, snapping photos and collecting data on their way to the outskirts of the solar system. The Soviet Union continued to send Venera missions to Venus until the early 1980s, some to orbit the world and others to land on its surface. Over the past 50 years, humans have tried to solve that puzzle. 'We started the task of trying to understand how the surface of Venus could be so far removed from previous ideas,' Kane said.

Its potential for life seemed to evaporate with the swamps.Д«ut while the fickle public turned its eyes toward the redder world of Mars, scientists continued to study Earth's twin. With a surface hot enough to melt lead, the planet was too broiling to host water on its surface. No longer a swampy sister, our vision of Venus became a hellish world with thick clouds, losing much of the attention it had previously garnered in science-fiction lore.

(The name is short for Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy.) Smrekar is the principal investigator of NASA's proposed VERITAS mission to Venus. 'The swamps digitally evaporated before their eyes,' Suzanne Smrekar of NASA's Jet Propulsion Laboratory in California told by email. When NASA's Mariner 5 flew by Venus in 1967, it revealed a surface temperature of 860 degrees Fahrenheit (460 degrees Celsius). In the movie, the fictional astronauts landing in 2020 encountered a swampland filled with dinosaurs, a very different environment from the Venus scientists know today.

He noted that ' Voyage to the Prehistoric Planet (opens in new tab),' the last Hollywood movie to feature astronauts visiting Venus, came out in 1965, the same year the Soviet Venera 3 probe launched, bound to crash-land on the planet. 'Ideas of a temperate or jungle-style environment at the Venus surface persisted until the mid-60s,' Stephen Kane, a planet-hunter at the University of California, Riverside, told by email.
