			Part II

Explore the internet to find 2 images related to astrobiology:

 - 1st image must be related to biology/life on Earth
 - 2nd must be related to something beyond Earth 

Write a full (lengthy) paragraph for each image (up to a page in length) 
stating the science content of the image. Specifically, explain what the 
image is and how the image is connected to astrobiology. Then, in a 
short second paragraph, briefly explain why you chose the image. Be sure 
to fully cite the source of the image (URL) and give proper credit. 
Include the image. It does not have to be high-resolution or on any 
special kind of paper. You do not have to print in color - black and 
white and grey are fine. But if you mention anything about colors in 
your text, you should print in color. (Note: If you choose a tiny, 
low-resolution, black and white image, and then go on to discuss details 
and colors in the image, the grade earned will probably be tiny too!)

Make sure your answer connects together your image to astrobiology, 
and in particular, the biology part. Ask yourself this question: 
"How does this relate to biology?" If you can't answer that, then you 
probably have chosen a bad image to use. Think of NASA's Astrobiology 
Roadmap, and how your image is connected with those goals and questions.
