Water is one of the most common substances in the Universe, and Earth has far more seas than land and life arose in the ocean first. Planets covered entirely in water may be common and abundant with life, including intelligence extraterrestrial life.

Oceanic Aliens

Oceanic Aliens (Narration Only)

For every yellow star like our own there are ten times as many smaller stars. Red Dwarfs are the most common type of star, outnumbering all the others combined, and as we head out into interstellar space to colonize the galaxy, the exoplanets around these red alien suns may be the most common home for settlers.

Colonizing Red Dwarfs (Narration Only)

Dark Matter Technologies (Narration Only)

Dark Matter Technologies

Science Fiction often shows us aliens and human living among one another in space, but how realistic are such portrayals and what sort of accommodation would extraterrestrials need for their environments?

Multi-Species Civilizations & Co-Alien Habitats (Narration Only)
