Read this article (click here) and then answer the following in paragraph format. Don't forget to ask another peer in a separate post about their post.


What types of elements present in other stars besides our sun might improve the chances of finding life on a planet in the habitable zone?


How do scientists detect the presence of these elements in distant stars? 

What is the habitable zone?



What mission has been sent by NASA to find planets similar to Earth?


What other factors do scientists consider when looking for habitable planets? Describe at least two.


Do you think that there might be planets that could host life? Why is it important to look for these planets? Or is it?
