A star is born through the gradual gravitational collapse of a cloud of interstellar matter. Both regions lie beyond the heliosphere and in interstellar space. The device allows for near-instantaneous travel across both interstellar and extragalactic distances. Supernovae are a major source of elements in the interstellar medium from oxygen to rubidium. Set in a universe where interstellar travel is possible. I civilizations would be incapable of regular interstellar travel. Beamed energy coupled with a vehicle scooping hydrogen from the interstellar medium is another variant. This effect occurs as giant molecular clouds condense out of the surrounding interstellar medium. The "Babylon 5" universe deals with numerous armed conflicts which range on an interstellar scale. This is due to the interstellar magnetic field of deep space. "Stargate", a film about ancient astronauts and interstellar teleportation, was released in 1994. It was the first polyatomic organic molecule detected in the interstellar medium. These are produced when accelerated protons from the SNR impact on interstellar material. Rockets are too slow to send humans on interstellar missions. The contents of interstellar space are called the interstellar medium.
