Maybe, interstellar biology has complex origins in both panspermia and independent abiogeneses.

Scientists define the beginning of interstellar space as the place where the sun’s constant flow of material and magnetic field stop affecting its surroundings. This place is called the heliopause. It marks the end of a region created by our sun that is called the heliosphere.

A civilization advanced enough to have developed interstellar travel must be communist.

In physics, the Jeans instability causes the collapse of interstellar gas clouds and subsequent star formation.

As we cruise through a fog of interstellar particles, we’re shielded by the magnetic bubble around our Sun known as the heliosphere.

A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases.

Voyager 1 has finally reached interstellar space.

Arthur C. Clarke, a British, and Samuel R. Delany, a mulatto American, both wrote sci-fi literature envisioning centuries of colonization within the Solar System.

Scientists have detected for the first time an interstellar asteroid passing through our solar system.
