Each planet is inhabited by different species.On earth the most intelligent living forms are called humans.While on jupiter they are referred to as "Julians".
They are highly advanced as compared to Earth.
When it comes to transportation we have airplanes,motors and electric vehicles,ships etc.
They just have highly engineered teleportation inbuilt system injected on their body by the government from their childhood.This technology defies the laws of physics in certain perspective ways beyond our knowledge.
This teleportaion cannot be triggered continuously but with a certain delay of time and they can trigger cryptic coloration(i.e camouflage).The extend of these abilities varies from one julians to another.
When it comes to outer space they travel by voyagers(ships) highly engineered combat ability with high endurance and immense speed.
The julians are believed to have migrated from a distint galaxy and upoun entering our galaxy suffered some technical failures on their voyager and was forced to land on jupiter.They have adapted and colonised the inhabitable jupiter with time.
Little do we know about them but one thing for sure they are coming for the other planets to colonise.And with this,pose a grave threat to mankind.
