OP_Return

OP_RETURN is a script opcode used to mark a transaction output as invalid. Since any outputs with OP_RETURN are provably unspendable, OP_RETURN outputs can be used to burn bitcoins.

Engraving a message into the bitcoin blockchain is possible. I used the free(!) service EternityWall.it It's extraordinarily simple.

Here is the transaction as seen from multiple Block Explorers:
