Some questions on DES Encryption...

('binary' encoding is not supported, stored as-is)

I'm not too sure whether this is the right forum to ask this but I couldn't find a Crypto mailing list so here goes:

I have a few questions on the DES Encryption algorithm:

1. In DES algorithm, given an encrypted text and the corresponding plain text for that is it possible to retrieve the key. Essentially, how secure is DES to known-plain text attack. I read some where that it is quite resistant requiring 2^55 plain texts to get the key but why is this so? What particular feature of the algorithm makes it this way?
