[QUOTE="Umbran, post: 2984102, member: 177"] If you've got telescopes like Hubble, no. Hubble can quite clearly make out other nearby galaxies, and we can get a pretty good idea of relative position that way. Remember, if you can figure out what it is from just a point (like many quasars), you can get a decent estimate. The real issue here is how much information you've got - do you know you're in the same galaxy or not? Same spiral arm? Exactly how quickly you can pin down your exact position depends largely on how quickly you can determine what reference points to look for - do you need to look for specific stars, specific galaxies, or specific quasars?
