text: According to the article, astronomers are interested in Venus because it was likely the most Earth-like planet in the solar system at one point. Venus used to be covered in oceans and supported life. Additionally, Venus still has features that are similar to Earth's such as a rocky sediment with valleys, mountains, and craters. Insight into the Venusian landscape would further allow astronomers to determine how closely related Earth and Venus were. The author also states that humans should not be limited by their fear to go out and explore. In the final paragraph of the article, the author describes how human curiosity will lead humans into many intimidating expidentures. However, the author believes that travels on Earth and beyond should not be limited simply due to danger, and humans should travel as far as their innovation will take them.
