“Earth’s Evil Twin.” NASA Publishes Exciting Information About Venus
 “Earth’s Evil Twin.” NASA Publishes Exciting Information About Venus 2329
The US space agency (NASA) has published a new video explaining why Venus has been described as Earth's "evil twin", as there are many commonalities between them.
Venus received this title, given that it is closest to Earth and contains similar materials, in addition to its close size, but it differs in many other ways.
The video, provided by NASA Planetary Science Director Lori Glaze, shows that Venus has a runaway greenhouse effect, due to a group of gases in its atmosphere.
Venus's atmosphere, which is 15 miles (24 kilometers) thick, is overwhelmingly carbon dioxide and contains clouds of sulfuric acid.

The planet has extremely hot temperatures of 900 degrees Fahrenheit (480 degrees Celsius), hot enough to melt lead.
"Venus is a crazy but interesting place, and so we want to understand why Venus is different from Earth," says Gleese.
Scientists and engineers from NASA and the European Space Agency, as well as European space agencies, are preparing to send three new missions to explore the planet near us during the next decade.

"Maybe something happened a very, very long time ago that made them take a different path," Glaze says. "Some people like to say that something went wrong with Venus, but I like to say that something good happened to Earth."
