text: Venus, earth's sister planet is currently inhospitable for humans. but in paragraph 6 it says, "Astronomers are fascinated by Venus because it may well once have been the most Earth-like planet in our solar system. Long ago, Venus was probably covered largely with oceans and could have supported various forms of life, just like Earth." Venus would have at one point in time had life living on it. That is why Astronomers are interested in studying it to learn what type of life lived on Venus and why they are gone. The author is intrigued by his imagination to know what type of creatures or plants that once belonged to this planet but are now gone due to the extreme weather conditions.
