You may have only sent 0.039 BTC to one address, but like in reality, when you pay with more than what is required, you are returned change. Thus, the extra address is your "change" address. So now one input for a future transaction is the address 1J9Etkj1BSfXDyaTzH7KypBbLmbbhENehc (which you've already used). Change addresses are what allow you to be able to keep n bitcoins and only spend partial amounts of it... Otherwise you would be forced to use up all the bitcoins in any given input. And hey, looks like your transaction has one confirmation now!
