Blog Post 3

1. What are the four ways scientists can detect planets?

Radical velocity, Astrometry, transit method, Optical detection.
2. Which way makes the most sense to you? Explain it.
The transit method is when a planet blocks out a star, and you can see a black dot moving.


The Goldilocks Zone

3. Explain the concept of the "Goldilocks Zone."
To be close to it's home star so that the surface won't get to hot nor to cold.
4. If Gilese 581c does have life, what do you think it would look like? How would it act? Would it be intelligent? It might be just a big ocean with land underneath it. It would act like a ocean with vegitation underneath.

5. Do you believe in aliens? Why or why not? Give me a solid paragraph. Yes, because there are so many other planets and also solar systems, so there might be a good chance that there might be life on those planets. Not exactly the aliens we would think, but like tiny microorgnisms. Another thing is people say they have been adducted so that's an indicator to me.
