When they finally reach the surface, they can then move unimpeded at the speed of light to reach earth in 8 minutes and 20 seconds, with far fewer obstacles to block them. Here's a picture for better understanding:
It takes about 43 minutes for light from the Sun to reach Jupiter. Here is a helpful link describing how long it takes for light from the Sun to reach objects in our solar sysâ¦tem.   http://www.pbs.org/seeinginthedark/astronomy-topics/light-as-a-cosmic-time-machine.html.
