panic report - Computer shut down unexpectedly--Can anyone determine cause?

I've never gotten one of these on my Mac before and it really worried me. Can anyone determine what is going on based on this panic report? 'Panic Report' alone is a pretty terrifying phrase to be associated with my beloved computer. Thanks for any help you can give me in advance!
