launch in 2029. However, newer research has shown that a thin atmosphere like that of modern Earth could have produced the same a General Description Of A Nitrous Fogger result. Today Venus is a hellish planet with a crushingly dense atmosphere of carbon dioxide, but billions of years ago, it could have had habitable surface temperatures and a watery ocean. As a result, the planets early ocean evaporated, water-vapor molecules were broken apart by ultraviolet radiation, and hydrogen escaped to space. Venus today is a hellish world. Venus, in this image, Venus is just beginning its journey across the face of the sun. Was Venus the First Habitable World of Our Solar System? Scientists long have theorized that Venus formed out of ingredients similar to Earths, but followed a different evolutionary path. In any case, the idea that Venus was once livable brings the planets cautionary tale full circle: Back in the 1970s, observations of Venus greenhouse effect heightened scientists concerns about carbon dioxide emissions here on Earth.
Way and his giss colleagues simulated conditions of a hypothetical early Venus with an atmosphere similar to Earths, a day as long as Venus current day, and a shallow ocean consistent with early data from the Pioneer spacecraft. The surface environment of Venus is a warning, the late astronomer Carl Sagan wrote. Many of the same tools we use to model climate change on Earth can be adapted to study climates on other planets, both past and present, lead study author Michael Way, a researcher at the Goddard Institute, said in a nasa news release.

That means an ancient Venus with an Earth-like atmosphere could have had the same rotation rate it has today. The result is mean climate temperatures that are actually a few degrees cooler than Earths today. Many of the same tools we use to model climate change on Earth can be adapted to study climates on other planets, both past and present, said Michael Way, a researcher at giss and the papers lead author. The analysis was published this week in Geophysical Research Letters. Thats the conclusion drawn from a fresh round of climate modeling conducted by scientists. And when the researchers ran the climate modeling software, they found that Venus could have been habitable for up to 2 billion years of its early history before the greenhouse effect took deadly hold.
A new research paper suggests that Venus could ve been habitabl e for hundreds of millions, if not billions, of years. The computer modeling wound the clock back on Venus climate, using calculations similar to those employed to wind the clock forward for our.
