It has a lot to do with speed. For instance a camera that has an extremly high ISO setting can pick up stars quick enough so that they wont blur without a tripod. Actually, if it's quick enough you can be moving and it still wont blur.

mcminty can probably explain it a lot better than I can. The actual mechanics of the sensor is beyond my knowledge.
Nice pic btw. I had to look at the full size to appreciate it.

My Rebelxti @ 1600 seems so pathetic after that..lolThe night driving stuff was shot at f/1.4 @ ISO 6400, with like 1/2s exposures. The 5D2 is so fast, I can actually hand hold it for star shots. I use a simple suction mount that goes onto the body of the car or the windshield.
