Astronomy 2 Arcticles II

1. Which article did you read? I read "Finding Twin Earths Is Harder Than Thought."



2. When was it published? It was published March 21, 2009.



3. What are 3 things you learned? I learned that scientists are close to finding an Earth-sized planet in an Earth-like orbit. I also learned that if Earth was the size of a basketball, the atmosphere would be as thin as a sheet of paper. The last thing I learned is that scientists are going to try to figure out if the other planet can be habitable.



4. What are 2 things you found interesting? I found it interesting that there may actually be another planet out there that is Earth's twin that may be habitable. Also, I found out that in order to get a detectable signal from a single transit, the sun and Earth would have to be very close beside each other; the Earth could blow up.



5. What is 1 question you still have? How are we going to get the Earth closer to the sun?
