The buzzing noise is a notification for a message. Go inside your ship, then go fore to the bridge. Look at the console and then read the unread message.
The message gives you the coordinate you need to enter to start hunting this bounty, but you'd be missing out if you didn't go look around the ship a little bit. If you go aft, then port, you'll enter your cabin, where you can find out more about this bounty hunter's life. Go starboard and starboard again to find the storage area, where you can check out your weapons and armor. Go port to the main deck and look at the "Fridge."
Then go fore, back to the bridge. Set the autopilot to 61145 and the ship will jump through space.
