user61749: I've looked at some of the more popular blockchain explorers, but none of them seem to provide the feature I'm looking for. I'd like to find a blockchain explorer that allows you to see raw Tx data and raw block headers. The explorer's I've seen parse the raw data and present it in a more human readable format. Are there any that provide the raw data?
Thank you!

user35931: You can use insight by bitpay:
/insight-api/rawblock/[:blockHash]
/insight-api/rawblock/[:blockHeight]
/insight-api/rawtx/[:rawid]


user1648: Updated for October 2021: blockchain.info (now blockchain.com) doesn't give raw data back just from appending ?format=hex to its usual explorer anymore. Rather, you have to use their API, which they document here: https://www.blockchain.com/api/blockchain_api
I couldn't get this to work in my browser, but at the terminal this worked for me:
% wget -O block154595.blk "https://blockchain.info/rawblock/0000000000000bae09a7a393a8acded75aa67e46cb81f7acaa5ad94f9eacd103?format=hex"


user63872: You can get this info from blockchain.info, by simply adding ?format=hexto the end of the relevant URL. 
For example, here is a recent block (height 509,244):
https://blockchain.info/block/0000000000000000000635bda771916ca727db53fea5441508f7161386e066be
And here is the raw data for that block, in hex:
https://blockchain.info/block/0000000000000000000635bda771916ca727db53fea5441508f7161386e066be?format=hex
(Note that you will need to parse the block header out of this data, as that URL will dump the raw data for the entire block)
Similarly, here is a transaction from that block:
https://blockchain.info/tx/74d350ca44c324f4643274b98801f9a023b2b8b72e8e895879fd9070a68f7f1f
And here is the raw data from that transaction, in hex
https://blockchain.info/tx/74d350ca44c324f4643274b98801f9a023b2b8b72e8e895879fd9070a68f7f1f?format=hex
